Firmware update experiences

Battery dropped to 5% last night so I thought it would be a good time to run the latest firmware updates. Here is how it went.

After clicking the install update button the following messages displayed...

"Updating Inverter arm" (from 0% to 45%)
"Updating Inverter dsp" (from 45% to 65%)
"Restarting inverter and waiting for firmware to upgrade" (from 65% to 95%)
"Updating battery arm" (95%)
"Update failed" (95%)

At this point the inverter firmware version was showing as having updated from D0.533-A0.533 to D0.534-A0.534 but the battery firmware version remained unchanged at 1040.

The install update button was still showing so I tried again and got...

"Updating battery arm" (95%)
"Update failed" (95%)

Retried several more times with identical results.

This raised a nagging doubt and so I checked the battery compartment (after shutting down and isolating the battery and inverter) and sure enough there was no USB stick in the port! I inserted an empty formatted USB stick, powered up the battery + inverter and clicked the install update button again. This time I got...

"Updating battery arm" (0% to 95%)

and then the install update button disappeared and was replaced by the normally visible inverter graphical strip.

Now came the confusing/worrying bit because the battery firmware version was still showing 1040 and I had lost the button to initiate another update attempt. Had the battery update worked this time or had it not? The system stayed in this state for several minutes until the battery started dumping its remaining 4% to grid as a recalibration commenced. As soon as recalibration commenced the battery firmware version changed from 1040 to 3005. Recalibration completed successfully with the battery charging to 100% and (touch wood) things have been operating normally since.

Moral of the story: If you have a new battery installed, make sure that it has a USB stick in it!

Additional moral: Don't take too long writing your account or you will find you have been logged out when you try to post it 😀 .

My experience was a bit different. The inverter updated first time, but the battery got to 6% and failed 3 or 4 more times before eventually updating. I have raised this with support. I have also slapped myself for doing this update while the battery had 80% charge, I should of waited. But there was a big button saying update.....

The update of both my AC 3.0 and 5.2kWh batteries seemed to go fine. Hit the update button and got a notification to say "updating inverter dsp" which got to 3% then stopped. The same thing happened with the other one.

Now both devices are reporting D0.534-A0.534 and Battery firmware 1041 - is that what it's meant to be? What's the deal with putting USB sticks in and waiting until the battery was virtually flat, is that an SOP I should have followed, or something? Everything seems to be working as it should, I hope I'm not in for some rude awakeneing....

JJB The USB thing is just errors from installation companies not putting them in.
The firmware for the inverter during updates goes onto the wifi dongle.
The firmware for the battery goes on a USB stick inside the battery.

Both the above should have been fitted by the installer - the wifi dongle is obvious, battery one is what installers tend to forget but that only makes the battery update hang. (I'm not entirely sure why they don't just fit the USB in the factory other than maybe there is a risk of smashing it off connecting the DC cabling)

Waiting until the battery is flat isn't part of the process, just people trying to minimise the cost of the update (battery takes itself all the way to 0 then back to 100% again)

hoggy Wow, thanks. I had no idea there was a USB stick in the battery, I will need to explore. I had thought, clearly incorrectly, that the battery could be updated via the inverter, being that it's meant to be one big happy family. I think my installer might know less about the ins and outs of the system than I do, now that I've had to learn about it myself. Thanks for the lesson ;-)

JJB Well your half right - the inverter does send the battery part of the update to the battery, it's just that if the USB in the battery is missing then it doesn't know what to do so just stops.

@Woodstock

Thanks for that info.

I had a similar experience; of my two AC 3s & 8.2s, one went seamlessly last night - battery & AC3 both updated correctly, the other AC3 updated, but the battery didn't - and seemed to fail similarly to yours, but without the missing USB stick!

George Rawding (GE) had a butcher's this morning, and deployed the firmware onto the errant battery's stick, remotely. The only thing now is that there's still no date against the 'Last Update' label, for that unit.

Both AC 3s are now at the same version as yours, but my batteries are at 3005. maybe there are different versions for different batteries or S/Ns?

I asked George to schedule the SoC re-cal for 00:30 tomorrow - when I'll start charging the EV - so as not to waste the full re-charge from the cheap tariff window this morning.

Something interesting came out of the conversation with him; he asked someone on the portal side why the re-cal had run, despite the update not having worked, and apparently, the re-cal run occurs first - irrespective of whether-or-not the update was successful!

Better get on and hit the 'Post' button - don't want to get logged out...!! 😆

I've been chatting to Rhys on the GE helpdesk and I must say that he's very helpful. They should have him doing their Dev roadmap!
He's managed to ascertain that both batteries have USBs in and he's also managed to update them both to 3005. So yes, they are now calibrating but were at least close to empty in any case, so it's only the pricey leccy that I have to put in now to take them up to 100%.

If it's not a silly question - how do you know if the battery has a USB stick attached or not - is it obvious on the outside or buried internally somewhere?

GrahamRead It was the same question I asked Rhys! Apparently they use a "hex code" to check whether the USB stick is there or not. Or you can take the front off the battery and check. It's probably best to contact them via phone or online chat and ask them to check and update from their end, certainly as a first step.

Sykes "Something interesting came out of the conversation with him; he asked someone on the portal side why the re-cal had run, despite the update not having worked, and apparently, the re-cal run occurs first - irrespective of whether-or-not the update was successful!"

This doesn't appear to tally with the invitation to upgrade on the inverter page:
"The inverter will be updated. During the upgrade procedure, the inverter will beep and its lights will flash. If the update was successful, the inverter will also reboot
The battery will be updated. If this update is successful, it will then recalibrate itself by fully discharging and charging its stored energy"

Not sure whether to upgrade or not!!

I am wondering if the hex code is checked by the givenergy commissioning team when the installer phones them. If it is not then maybe it could be, should be.

Do you have the open the battery case to get to the usb slot? Or is it on the outside?

THALL Not 100%, but pretty sure it's not on the outside - I went and looked at both my batteries after reading this thread, and apart from the back hidden up close to the wall, couldn't see anything resembling a USB stick or slot for one; so I assume it's internal

Its inside it at the top. (obvious disclaimer regarding not taking covers off without isolating/knowing what your doing)

I've had the same issue - the inverter updated OK, but the battery failed to progress. I tried 5 times, then rebooted the inverter and tried one more time - every time it made no progress (stuck at 6%). I've updated the battery previously, so was pretty sure there must be a USB stick, but I took the front panel off to double-check (and indeed there was one).
I'll be speaking to support tomorrow I guess (had enough for tonight).

Hi. My update went smoothly. Both the AC3 and the 5.2 kWh battery upgraded.
Versions are D0.534-A0.534 and 3005

I too do not have a date/time against the battery.

Phil-C I too do not have a date/time against the battery.

Interesting!
The inv / bat I have, which both updated correctly, have a 'Last updated' date beside them now.
Not sure why yours wouldn't have the same, as it went smoothly...

Sykes My battery firmware updated from 1040 to 3005. Was half expecting it to go to 1041 as some others seem to have done but that was not the case. My battery is BG series (new) 8.2kWh. I too am wondering if there are different firmware versions for different batteries or S/Ns.

After the installer left I went through the rubbish and rescued various zip lock bags of unused terminals, rubber grommits, screws, washers etc. . I have just checked through them and a careful examination of the one containing metal bits revealed the missing USB stick. It is not immediately apparent that it is a USB stick as it is an oblong of folded shiny silver metal open at both ends. On close examination a USB plug can be seen through one end and a memory board through the other. Plugged it into the PC and found it to be formatted, empty and have a capacity of 59.8MB. Now wondering if it is of a special shielded or heat resistant design so I think I will use it to replace the standard plastic cased USB I put in when the update failed.

Ran mine last night.
Inverter FW remains on 449
Battery FW 1037 > 3005
Capacity 151.77AH > 151.88AH so no real change at 7.7kWh
No real issues or glitches - 1 click wonder.
The battery did do some sort of extreme discharge beyond even a normal calibration discharge. Ended up taking the pack down to 43V and triggering a BMS low voltage alarm. Not sure if this is intentional or not but it's recovered fine and that's still 2.68V per cell so OK for a one off.

I emailed support but hadn't heard back from them, so I tried again last night and this time battery update (1039 to 3005) was successful on the first attempt. After recalibration, the Full CAP has dropped from 186.11Ah to 181.87Ah. It took 12 minutes to do the f/w, 23 mins to discharge from 4%, and 3.5 hours to fully charge after that (which was much quicker than the update in October) The inverter f/w update the day before took 18 mins (D0.533-A0.533 to D0.534-A0.534).

Wednesday my inverter update succeeded but the system no longer functioned correctly and the firmware had to be regressed by GE. As the latest firmware didn't support the LoRa CT clamp setup I have. My battery has never installed a firmware update - I know it's got a USB stick in it as the installers couldn't find one in the packaging and I supplied a USB stick I had lying around (At 64Gb I think it's probably a higher capacity than the battery supports).

Does GE have a pilot group of customers to validate firmware? If so how do I enrol? If not should there be?

TonyHayden The USB stick that came in my packaging was 59.8MB capacity and the one I used temporarily to get my update to work (as the supplied one was still undiscovered in the packaging and not in the battery!) was 28.6GB capacity. I have now put the supplied USB stick in the battery and will find out if it works OK when the next update is installed.

The battery appeared to work fine during its first two weeks of operation with no USB stick in place and it only became an issue when attempting to install the upgrade. The temporary USB stick I used was formatted and empty before the update and also when I checked it again afterwards. It looks as though it was only used to hold data during the update process and this was deleted on completion.

Woodstock Thanks - do you know which file system the stick was formatted as? NTFS or FAT32 maybe?

Don’t think my attempt at upgrading worked despite the portal now saying having a firmware last updated date as the inverter and batter version numbers remained the same. However I don’t have the option via the portal to try again, which would be strange if the firmware is out of date. The internet connection seem to be lost at some point in the process, so maybe that stopped it, but the batteries still went through the recalibration process.

If you have 2 8.2kWh batteries, do both need the USB stick to do a battery update?
Also, where are the details of what fixes or changes the upgrades include?
At present, our system is working OK, so am reluctant to do upgrades if not really needed and they are likely to cause problems.

Woodlands The firmware releases are documented at https://kb.givenergy.cloud/

I notice the update button has disappeared. I haven't done the update yet , does this mean I have lost my chance?

TonyHayden The temporary (28.6GB) USB stick I used for the update was formatted FAT32 and the supplied (59.8MB) USB stick, now fitted in the battery, is formatted FAT. The FAT32 formatted USB allowed the update to proceed without problem. I have yet to perform an update with the FAT formatted USB in place.

I ran the update last night, and while it seems to have upgraded the battery firmware from 1039 to 3005, the inverter is still showing version D0.449-A0.449.

The update didn't mention the inverter firmware, at least when I was watching it, it seemed to go straight to 'updating battery arm'.

My 'Full CAP' has gone down from 191ah to 185ah, and the system is about 1 month old.

Where are people finding this 'full CAP' value?

c_squared It's in the 'old' (non-beta) portal, if you go in to System on the left and then pick View from the Actions menu against your inverter, and then in the BAT cell tab on the resulting page.

Damien thanks. Quick check, the battery is only a week old to me and showing 190.

Oh, I shouldn't have tried the upgrade really - I did it because the battery was already at 5% so seemed an ideal time to try. The Inverter now reads D0.532-A0.534, which doesn't match any release on the knowledge hub page, and the battery firmware hasn't changed.

Battery currently recharging.

Damien Thanks for that! I have been using the new portal and didn't know about the BAT cell tab etc.

Woodstock

Woodstock After failing to update the battery firmware for about the 5th time last night, I am still on 1040 with two BG series 8.2kwh batteries. Since you have upgraded to 3005 I think I will try again. Last night I watched about half an hour of "Updating battery arm - 5%" through to "Verifying update - 99%) when I went to bed. My phone app indicated Discharging at 2.5Kw so I thought the recalibration had started.
But in the morning: "Update failed - 99%", one red light and 0% SoC! (ie it missed Octopus GO).
Oh well...

Aha! I just tried to Update again and got the message "the inverter is already up to date"
On the Beta portal is still said "Update failed - 99%" and showed the battery version as 1040
But then I checked the old portal and under System it showed the Battery as 3005 !!
So maybe the the update I did at midnight on the 15th actually did work but the reporting on the new portal is faulty?
My inverter shows D0.534-A0.534

Ok just refreshed the Beta portal and it is now showing 3005 (it was left open on my PC all night...)

My experience as a newbie to the forum is a bit apprehensive really. Having suddenly experienced my batteries (2 x 8.2KWh jobbies) start to differ with only 4% SOC showing in the app and online portals, the LED indicators on the batteries were showing 1 at 4% and the other anywhere between 10% and 45% or 3 x green LED illuminated. (GivEnergy, please address the strange illumination patters. Normally, I would imagine most people would expect 1 LED < 25%, 2 x LED 26% to 50%, 3 x LED 51% to 75% and 4 x LED 76% to 100%). Having contacted support, Adam suggested the inverter needed updating but he needed permission from me to do that, I agreed and left it all to him. I then noticed that, although the inverter / controller had been updated and I was drawing some 5.4KW from the grid, the batteries were still showing 0% (after an hour or so). I again contacted support where Adam told me he'd been trying to update the batteries but it wouldn't do it for him. Could I follow these instructions and get back to him:

To do this you must follow the directions below.

Isolate the green handled battery breaker (mine is red)
Turn the batteries off on the black buttons (press and hold)
Remove the front covers on the batteries (weigh about 10lbs and have earth bonding that restricts distance)
Remove the silver USB from both batteries (DO NOT DROP THEM)
Plug the USB in a PC and place on the file attached (remove anything currently on there) (Luckily, I work SE in IT and have PC's readily available)
Repeat this on both batteries
Plug the silver USB back into the battery
Place the front cover back on (awkward)
Turn both batteries back on
Turn the green isolator switch back to the up position. (Mine is still red)

Duly done, I get back to them and bugger me, they've all gone home. 1710hrs if you're interested.

In fairness, it was an easy job but I'm not sure I should have to do it. If you need to do this and are not experienced with what not to touch, I'll just say for heavens sake, don't drop your Allen key (for the front covers) or the USB stick into the battery box, it could get a bit noisy and you could look like Ken Dodd! (Bless him). 8KW of power is quite a hefty whack if you get it wrong.

Oh well, I suppose I have to wait until tomorrow?

adrianscotter can you not just run the update from the portal yourself now?

wrefordj A quick update: after finally getting my battery firmware upgraded, it seems that somehow my two batteries (2x8.2Kwh) got themselves unbalanced which shut the system down. Adam managed to sort this yesterday with what turned out to be a short calibration and now everything is running ok.
It would be good to have notices on all the portals and Apps saying whether or not they are still active. I notice that the battery status page seems to have been withdrawn from the old portal/System/Actions/View page. Is the State of Charge still correct on the phone App?
Lastly, I do have some electrical engineering experience from many moons ago, but I am struggling to understand exactly how the inverter solves what must be quite a complex monitoring and controlling problem. Especially when working in conjunction with a third party like Solar Edge, in my case. Does anyone have a good reference for an outline explanation, please? I'm sure that if it were straightforward, we wouldn't be experiencing quite so many hiccups that GivEnergy are doing their best to solve.

Hi. I've tried the update twice and managed to get to 99% before upgrade failed - managed to recharge and recharge batteries twice though....
Anyone know where I can find the update log file to see exactly what is going on?
Thanks

Chanced Mine failed at 99% also. This was indicated on the beta portal. When I subsequently checked the original Cloud portal, my battery firmware had been upgraded, so it's worth checking there, perhaps?

thank you - had a look and it shows the same version in both portals

hmm, just tried the update again - and it fails almost straight away - inverter failed to update. Think I'll need to wait until Jan and give support a call. The system seems to be working fine.

It might be failing because it can't get to the repository as its not a secure site currently as the certificate has expired.

anglefire ah, good point. I'd noticed the (battery) api I call was failing for the same reason.

adrianscotter
Hi Adrian,
I tried out the beta dashboard 2 weeks ago and when it seemed to be behaving in a way I didn't expect I attempted to update the firmware for the inverter from the software tab (on 534). It failed. Since then my system has been unresponsive to the octopus scheduler, the beta dachboard and the legacy dashboard, although online, I'm waiting for support to take a look still. My batteries 8.2kWh x4 do have the USB in with "ZH01.BIN" file, You mentioned on your post placing on the file attached to the USB stick via your PC. Is that a firmware update & if it is where can I find it?
Thanks
Chris

For the record....I attempted the upgrade again last night. The inverter is now at the latest version and the battery upgrade appeared to have worked based on the online progress messages...however after the discharge and recharge cycle the inverter went into idle and refused to start up. I notice that the batteries have not been upgraded to a new version beyond 1041.

This morning, after turning it all off and one again - to no avail - I had to contact the givenergy online help, Dan was excellent - given it's news years eve and they are probably on skeleton staff support, quick to respond, and a remote restart of the batteries seem to fix the issue and the inverter started.

Makes me rather wary of trying an upgrade again tbh.

Forgive the ignorance of a newbie, but nowhere on the portals or app, legacy or otherwise, can I find a control to force a firmware update. Mine is on ****53 and 3001, is there any/much value in updating?
System seems to function as it should, and responds properly to mode changes.

Mines failing too. Not sure the benefits yet - something to do with calibration from memory - which isn't good!

wilfleek On the beta portal, inverter card, Software, if you are not on the latest version there should be a button to upgrade. Remember that there will be a recalibration if you kick this off (and it succeeds), which will empty and then fully charge your battery. The release info is on https://kb.givenergy.cloud/

I’ve tried multiple times over the last few weeks, but no change of version number for the inverter or batteries and no indication of what the problem is. Not sure I’ll bother again as I’m not waiting up to setting it going during Go cheap rates or really want it doing the battery calibration on peak rates repeatedly.

andrew_bond Found it, thanks.

Well, that didn't go too well, The Inverter software shows as having updated, the battery firmware has disappeared totally, and the inverter is in a fault mode that rebooting won't cure. Further attempts to update result in "update failed" messages.

Result! Guess I will have to speak with support - what is the number for that?

wilfleek The number for support is +44 1377 252874. If you use facebook, I always contact them via messenger and get an immediate response. Are you sure the battery isn't re-calibrating, as it will do this after a firmware update

Kevsla Thanks - Yup, pretty sure, all coms lost, battery status not changing. Wifi dongle flashing continously, so that isn't connecting for some reason.

Edit - dongle light now steady so some hope! Will leave it overnight, you never know.....................but light on inverter still red, so a fault condition of some sort.

Well, a thumbs up for tech support - a small .BIN file emailed to me and dropped onto the wifi dongle, with several fragments of incomplete files removed, and we are back up and running. Inverter firmware shows as ***-534, battery as 3001, I suppose a calibration cycle is needed on the battery to update that, we'll see if that happens, at present the panels are filling it nicely. 😄

I am keeping away from that "update" button for a while..................

wilfleek
How did you get the .Bin file sent to you?
I have checked I have the usb fitted which it is, but there are no files on it, when it tries to install the update it starts at 95% and ends at 99% which seems incorrect if there are no files to install. so I am guessing the only other way is to download it manually. I have 3005 but it keeps trying to install 3007.

The .bin file was emailed to me, I put it onto the battery usb sticks after deleting anything else on them, then refitted them to the batteries, master first, slave second.

cheers
do you remember who sent you the file or how you requested it?

The file can be sent by GE, open a support ticket.

They will also co-ordinate a calibration once you have loaded the file on each battery.

What TheDragon said.

Updated an 8kWhr battery fro 3005 to 3007 at 11:00am yesterday (Sunny afternoon predicted and happened) . Hit the green update button. Watched it for a couple of mins to ensure it was updating. Then ignored it until 23:00hrs. New system seem less lossy during the night, and is quicker to react to the kettle at 5am (no solar - battery only operation) was_10secs now _3secs. So my update went smoothly - so far.......

Brookydave There've been other posts relating to this sort of behaviour. I think if the inverter is supplying house load from PV and you switch the kettle on, if the inverter has to start pulling from battery to supplement the PV, it takes time to get going. On the other hand, if you're already pulling from battery, then ramping up can be quite quick. However, if your test is a usual 5am "how long 'til grid import tails off?" then this does sound a better response time.

Brookydave How could you tell it was 3 seconds vs 10 seconds? I thought the app at best updated once every 10 seconds? Or are you using GivTCP?

i've tried to update a few times this week. Click the update button, accept the warning, watch the messages saying 'restarting' etc - nothing happens. Still at 3005
Anyone know how to resolve?

ivell Give them a call and ask for help.

Tim yep i can do that of course. Also using this forum as intended 😆

Well after the many failed attempts by myself to carry out the battery upgrade to 3007 Gareth managed to to it remotely. This then recalibrated the battery as it is supposed to do. The process took around 6 hours but where the battery was charging in 20 mins (1.1kw) and discharging in around the same time now it’s taking around 3 hours to charge (4.7kw) couldn’t be happier. Thanks to the team for being so quick to react and I am delighted with the result.

I will be honest and say I have not read the 70 posts above, but I just noticed since upgrading to 3007 battery firmware my charge setting did not apply and the battery was charging from the grid over night even though it should be discharging to 30%.... Not happy with this firmware or the upgrade process, lack of notes/general information. Also getting a bit miffed with GE support, I raised the issue 1 week ago and not even an reply email to acknowledge the issue. I now have 3 support issues open and not had a single reply.

THALL my experience too. Long wait times on their phone support when I try to get a reply on this issue

@MadoMich did you get Gareth to sort it via phone or email?

Fully discharged my battery this morning as the agile outgoing price was good and I knew there was plenty of sun on the way to charge back up. I have an 8.2 kWh full DOD battery and the information on the portal says it took 5.8 kWh to charge from 4% to 100%. Shouldn’t that be closer to 7.8 kWh? If so, where has my extra capacity gone? I’ve raised this with GE support and will wait for a reply from them.

ivell hi Ivell I wrote the details of the problem I was having to support@givenergy.co.uk. At 19:00 and had a response by 15:30 the next day.
You may think the response time was slow but he had fixed the problem, carried out the update to 3007 and initiated the battery calibration program which my system was in great need of.
I must admit I couldn’t fault the process and I am absolutely over the moon with the results.
My 5.2kwh battery now lasts the whole night even when the dishwasher has been activated in the evening.
😁

Hi, just to add my experience of the upgrade to 3007. I was holding off doing the update as a few people seem to be having problems but my patience ran out so I went for it on Monday. The update installed without any problems and the battery then did it's calibration as expected (I lowered the battery charge rate so this all came from solar). My first full day's grid usage after the upgrade was pretty much the lowest I've ever had since having the battery, which could be just a massive coincidence, but I would say that (for me at least) performance on 3007 is definitely better and looking at data coming from givtcp does seem to confirm this.

judgepd I did think I was imagining it but it does seem a lot snappier to react to loads. Not sure if this is an undocumented change or it’s all in my head though!

MadoMich so i emailed on 11 Jul and no response. no update. no nothing

I forgot to say my firmware updating issues are now sorted. Turns out my settings were not applying. Hit the reset to defaults, waited for the system to come back online. Set eco to on, set my timed charge period and everything is back to normal. Average day is 450wh. GE Support says I edited my settings July 5th, but I do not recall it, no need to do it so who knows. But basically turn it off and on again worked for me.

THALL ok giving that a go..

Well, despite my misgivings (due to previous experience!) I hit the "update" button. It seemed to work in that the portal reported all was well until the progress bar stuck at 99% on the "verifying update" stage. After leaving it for a couple of hours I forced a complete discharge and recharge of the batteries in case that would help. It didn't.
This duplicates my previous experience, I guess I will now ask support for the .bin files, and drop them onto the battery memory sticks manually like I did before.

Hey ho. At least my system is still working.

wilfleek The manual way is best. Just a pain now needing your engineer or GE to initiate the calibration.

chris_p I was using a UK smart meter display that shows the power usage.

I had my new firmware emailed about 3 days after I emailed support - but still have to do the update - don't really want to waste the energy for what for me will be a minor improvement on the battery voltage reporting I believe.

Updated to 3007 today. Battery was showing 25%, then I started the update. Battery showed 100% as the drain of the battery started. It got to 70% then dropped to 0% before starting to charge again at 470-500w. It stayed at this rate for about 30 mins then moved to the set charge rate and has been going ever since. Now at 40% full.

Well, although the performance of the battery seems to have improved, the SOC calibration for me is really not great. My battery just went from 85% to 100% within 5 minutes...clearly not correct. This does seem like a really basic issue that givenergy just can't quite get right.

judgepd Can't say I've been able to see much battery ramp up performance either really. It would be great if someone from GE could do a QA at some point and address these issues with customers.

wilfleek same experience here.

I updated my single battery to 3007 over the weekend and GV triggered the calibration yesterday morning - did exactly what its meant to do and discharged at full chat - did some twiddling for a few minutes and then charged at full chat until full. Very smooth line on the graph. Some of the charge was the sun, but still a bad day for import - not as bad as Sunday - but bad! 🤣

chris_p Updated to 3007 today. Battery was showing 25%, then I started the update. Battery showed 100% as the drain of the battery started. It got to 70% then dropped to 0% before starting to charge again at 470-500w. It stayed at this rate for about 30 mins then moved to the set charge rate and has been going ever since. Now at 40% full.

When you say 'set charge rate', is this a maximum rate that you have chosen, or the maximum capability of the inverter/battery combination?
Just interested if the battery re-calibration insists on using it's own discharge and charge rates, or if they can be optimised somewhat by the user to reduce the energy costs of the process.

Simon_C I set the charge rate before doing the update and it uses whatever I set whilst performing the calibration. So I went for 2kWh so that I had some room for consumption whilst calibration was occurring.

Simon_C Pre 3007, calibration used whatever charge/discharge rates you had set and I don't think this has changed. What has changed is the recharge bit of the operation. Previously calibration kept control right though to 100% SOC before reverting to whatever operation settings (ECO etc.) the user had in place. Now it seems that calibration keeps control only until 4% SOC is achieved before reinstating user settings. Seems very weird to me as (especially in winter) it could be days before calibration is completed by the battery achieving a true 100% SOC !

I had my battery (8.2kWh) and inverter (AC3) installed in Dec 2021.
I have NEVER been able to update the firmware online.
Twice I have had new battery f/w emailed to me and I have installed it manually
I've been trying to install the new f/w for a while now. As I had a notification it was available.
My current f/w are D0.534-A0.534 for the inverter and 3007 for the battery. I would very much like to have the newer battery f/w as it is supposed to fix the sudden "drop to zero" problem that I've had since installation.
I've run the update firmware on the inverter panel but it always fails at 3%.
BIG problem is that due to a debilitating illness during 2022 I am now physically unable to access the battery to remove&replace the usb stick as I have done previously.
Are there any ideas how to make the update work.

Nev Young Hello Nev,

The easiest way, is to check why the dongle connection maybe being interupted. The update is 1st staged on the dongle. Then once complete, loaded to the battery, over the ModBus connection.

You might also be good updating the Inverter from 534 to 535.

The newer aftger that, is still in beta testing.

As a LAST resort, do you have any friends, who can assit you, do manula loads of inverter and BMS via USB.

If the dongle is being interrupted then it is faulty! None of the other devices at my home have any connection problems.
Update the inverter - How?
And yet another "last resort". I think it's about time it was fixed or replaced.
I've had over 15months of (ok intermittent) grief from this system. Features that have NEVER worked.
For an outlay of over £7000 If it's not right then I would expect a team of engineers to turn up and sort it out.
You may gather I'm getting right royally pissed off!

UPDATE.
Givenergy emailed me two f/w files and instructions what to do with them. This involved removing the dongle and copying the files onto it using a PC then re-installing the dongle.
I think this has found the problem why my system could not update f/w online. The USB inside the dongle was write protected! I managed to make it r/w by holding the reset button in for 15seconds. I could then do the copy etc.
Sadly it did not update the f/w versions so I don't know if I was sent two old versions or new versions.
I guess I'll have to wait for the next update to find out if it's fixed permenantly.

Oh and the new f/w hasn't fixed the drop to zero SOC.

update: July / Aug 2023.
OK new battery f/w is now available. When I try to update it gets to 90% (verifying) then sticks there. I get a failed message about 2 hours later. So my previous hope that the previous manual intervention fixed the problem was in vain.
current f/w versions are: D0.535-A0.535 and 3007.
I guess I'll have to get someone in to do yet another manual update for me as GE and the installers can't (won't?) do it.

As an asside the inabilaty to fix these problems has now cost GE about £10K as I persuaded a friend who was going to get a GE system (solar panels plus 2x9.5KW batteries) to take his busness elsewhere.

I have a friend who is willing to "have a go" . Will GE accept liability if it goes BANG and burns my house down?

Nev Young

Got any lawyer friends 😂😂

Surely by now they have offered to help your installer or work with you to resolve the firmware update problems?

kram BWAHAHAHAHA
I don't think they have a clue. I've asked both the installer and GE to fix it and they are unsurprisingly silent.
Any way the update button has now been removed so I'm stuck on 3007.

THALL Let me guess, the big button was also red? 😃

Edit
ggrrrrrrr just realised how old this thread was hehe

Nev Young if you contact GivEnergy support they can push the update out remotely for you

I did see a post on the Facebook users group suggesting that GE have paused all FW updates over the portal until they can understand why some work/some don’t. And there was the suggestion that such “over the portal” updates are being moved away from in favour of “installer local updates”. Can @TheDragon (GivEnergy) comment on this? Rumour or fact?

Smk82 I've no idea what the reasons are I'm afraid.

I don't work in tech support.

"Installer local updates" - no way. My 'installer' would charge £500 for a half hour visit - that's if they can be bothered. There is also a good chance that they would screw up ...
