a new data dongle to my 5kW Gen 1 inverter

I have a GivEnergy install consisting of a 9.5kWh battery, a 5kW Gen 1 hybrid inverter and 12 JA Solar panels [405W]
Some weeks ago, all connection between my data dongle and the internet ceased and the dongle has continuously flashed blue ever since. All attempts to reconnect the unit have failed and I concluded that the Wi-Fi receiver of the dongle itself is broken.
I have bought a new dongle from ABC renewables and would like advice on how to hook it up.
I am aware that there is a token file on the original dongle which is registered as mine in the data app, now run by the former data department of GivEnergy. I am signed up for the premium subscription.

Question 1.
How should I go about replacing the old dongle with the new?
a. Should I cancel my data account and sign up for a new account with the new dongle?
b. Or - should I overwrite/replace the token file on the new dongle with the one on the old dongle [Assuming the storage system on the old dongle is intact] and then continue to use my existing account?
Question 2
Should I close down the whole system - following the GivEnergy training room YouTube video - replace the dongle and then restart the system, again following the training room video?
If the new dongle functions correctly, I know how to reconnect it to my internet, but is there anything else anyone can suggest that I should do? Advice will be gratefully received as comprehensive searches in these forums has not produced a systematic set of instructions for my situation, and bits and pieces from all over the place can be so confusing.

ed-form No one able to offer advice?

Not sure if there are any other posts on here about this. Have you asked your installer, I guess they should have had some instructions on this as part of their install process ? And presume you have gone through the troubleshooting/update as described here.

Maxwell Thaanks for the reply.
Sadly, I cannot contact my supplier as they closed down some time ago.
I cannot do any tests on anything because the dongle simply fails to respond. It is flashing blue continuously and has been for weeks now.
The bit I really need advice on is how to deal with the MSN file - as near as I can tell from the various posts on this forum, the MSN file needs to contain the serial number of the failed dongle, but i could really do with a simple summary of how to deal with the MSN file from someone who knows.
I can handle setting up the connection to my Wi-Fi; I've done it twice before after changing broadband providers, but it's no use connecting it if the data it transmits is wandering off into the aether rather than arriving at my data account.

ed-form According to co-pilot (and that must true 🙂 ) dongles in gen 1 kit don’t store the account details. Those are stored in the cloud. And there is no file to transfer over. Just need to go and set up your new dongle from the start. But I haven’t done that so can’t confirm if true.

Hmmm! That suggests that the data packets broadcast via the dongle must have the inverter identity coded in them so that the data gets sent to the right database location.

Take the old dongle out the inverter, plug it in to a laptop, copy the MSN.txt off it, plug new dongle in, paste MSN.txt (if your bothered then take a copy of that MSN.txt if you want) remove dongles then stuff the new one in the inverter and setup WiFi as normal.

All the MSN file is, is the dongle serial number printed on the sticker, that's the only thing that makes them unique.

(& Yes until a year or so ago you could put someone else's dongle serial in and it would block theirs from connecting - but the portal eventually got wise to this)

hoggy I'm grateful hoggy. Will get on it later.

OK. I've altered the MSN.txt file on my new dongle to match the serial number of the old dongle and I have a simple question...
I pulled the old dongle with the system live; is it OK to insert the new one while the system is running? It's a USB device so it should be ok, but a 'Go ahead' from an expert would calm my nerves.

Not an expert but I would think it's not "Plug and Play". But like a sponge always willing to absorb until I need a memory dump.

I've yanked them out and put them back again no bother (that's not to say I didn't get lucky) BUT I suspect it may be best to power everything down first on this occasion as to ensure the change of serial gets picked up.

hoggy Thanks hoggy.
It's up and going. The dongle is new and has a different serial number, but I changed the MSN.txt file to carry the serial number of the old dongle. After about 5 minutes data began to appear in the GivEnergy cloud displayed in a browser.

Investigating the equipment page, it seems to be offering me a battery update to 3022. Is it OK to do this?

Bobanthony It all seems to be going - I was too frightened even to turn the system off. 🙂
