funny tick between 98% & 100% ?

The little tick up from 98% to 100 and back to 98% then going idle until it discharges a few % has been happening every day for about 10 days, prior to that it would go all the way to 100% before going idle, its not really a big deal in terms of how it operates but seems a bit strange, anyone else getting this ?

My battery doesn't seem to behave like that but still similar. What I noticed is that it doesn't like to charge the battery when the displayed SOC is above 96%.

So, I don't think there is anything wrong with your battery, but let's hear what the experts say.

rio911 from what I've read in other posts, the system won't charge the battery after its hit 100% until it's gone down past 95% to avoid power cycling.

spawneydave I've seen a similar thing on mine where it'll get to 100% and dump energy till it's back to 98%. I've always put this down to a calibration difference. But I'm no expert.

#5 ProximusAl

thewhalw21 Exactly the same for me. Charges to 100% and then drops to 98% and stays there.

ProximusAl I've read alot of people that say there's gets to 100% and then their solar shuts off. Maybe this is a "work around" on newer installs. Mines < 1 month old

#7 ProximusAl

thewhalw21 Mine was installed 2 weeks ago, and it has done this since install.

ProximusAl WHat Inverter serial please, I will take a look

#12 ProximusAl

TheDragon (GivEnergy) Not sure if you've done something or not on mine, but I can now see the update firmware button is available. I will not do anything at all until you have confirmed you have finished looking 🙂

#14 ProximusAl

TheDragon (GivEnergy) Thanks ever so much!! Really appreciate it.

On an absolutely minor note, on mine the picture of my HY5 Gen2 shows a Gen 1 (Dongle sticking out the bottom, whereas my Gen 2 has a little Wi-Fi antenna). This is absolutely minor, but wondered if this is expected?

I see exactly the same:

Is this a firmware or BMS thing ? ( ED2248G036)

#17 thewhalw21

justpassing I think so, I was on 906, now on 994. Still got a battery update pending but SOC has been stable at 100% now. Tho the battery is still charging and discharging every 5 mins. Think it may just need to calibrate itself again with the update.

#18 thewhalw21

ProximusAl Hey, have you updated to the new battery version? Mine seemed to only calibrate back up to 20% then stopped and wouldn't charge or discharge.

#19 TheDragon (GivEnergy)

thewhalw21 ill sort that, be same issue as Prox.

It will calibrate up now

Feel free to temper the charge power if you wish, just takes longer

#20 thewhalw21

TheDragon (GivEnergy) Cheers, Was just scrolling through Prox's messages in the Beta thread and was about to ping you a message. Thanks for sorting 🙂

#21 TheDragon (GivEnergy)

thewhalw21 Hands up, my bad. When the Inverter FW went on, the Inverter needs a full total initialize. I forgot, so the symptom it will only grid charge to 20% and stop.

So thanks fro reminding me

#23 RHardie

Sorry to hijack your thread but I seem to be having the same 98%-100% problem. I was hoping the problem would resolve after the battery firmware update but it hasnt. It seems to get to 100 percent then dump 2 or 3 percent to the grid and sit at idle. My s/n is ED2248G069

#24 justpassing

RHardie yes, still the same here ( after 3012 ). I believe it is an inverter firmware issue rather than BMS. Hopefully all fixed when the new firmware comes out.

#25 Rodmac76

Same issue as above 100% dropping to 98% idle ED2152G223 again assumed battery firmware would fix.

#26 RHardie

I wonder if @TheDragon can help us? 😀

#27 Roberto

Mine cycles too between 98 and 100% but only when charging from grid. From solar it stays at 100%.
3012 didn't fix this issue as i believe it's an inverter issue rather than a BMS one. The forthcoming inverter FW might fix it?

#28 THALL

This is fixed with an inverter firmware which is still in testing. As far as I can remember, Gen 2 hybrids have a fix, Gen 1 next then AC units.

#29 RHardie

THALL thanks for the reply. Any idea when the gen 2 inverter firmware will be released? Alternatively could I become a Beta tester? I'm impressed with the new BMS firmware, my battery capacity is much higher since the update. Fingers crossed the inverter update will fix the problem and I'll be a happy man.

#30 THALL

RHardie No idea of ETA. I would say soon if I was to guess. They are not after anymore testers at this time.
