Twice yesterday my battery seemed to do a rapid discharge for no reason.
So between 06:50 and 07:20 it has fallen from 45% - 19% without significant load happing in the house, but then between 22:30 and 23:15 it fell from 84% to 1%. You can see that it was also importing during that period.
Any idea why it would do that?
Cheary See also https://community.givenergy.cloud/d/4508-odd-battery-discharge which was similar. Though it's interesting in this case that it had just charged up to 100% on solar, so a little hard to believe that it was unable to track the charge state here.
Perhaps a weak battery cell? How old is your system? Were there any notifications about over- or under-voltage ?
If you use android, I'd suggest https://givenergymonitor.wixsite.com/tutorials which is a 3rd-party app which can show more internal details about the inverter than the standard app, including individual cell voltages.
Thanks for the reply.
Its a new system, 4 weeks old, 9.5Kwh Battery, 7Kw Solar.
Looking at the graph I've just noticed the charge from solar at 12:00 seems far too rapid also, its gone from 20% to 100% with not enough solar to justify that.
I'm not sure where I would see the notifications about under/over voltage, but I have not noticed anything.
I'll have a look at that app, thank you.
Cheary Might be worth speaking to your installer or GE support, either of whom ought to have remote access to your system.
