Battery stopped charging after summer time to British standard time

#1 maxhume 2025-10-26

Anyone else had this issue? I've shut everything down and restarted it all but the issue remains?

maxhume GE automatically send an update to adjust the time. You should be able to see this in the activity log on the portal. You could check if any other changes happened at the same time.
Do you mean it stopped charging from grid, or from solar?

My battery hasn't charged from grid overnight, had assumed this was from something I'd done wrong setting up predbat but that is still in monitor mode.

After the time change I can see the AC Charge enable state was read by predbat and this came back false. Can't see anything changing the charge option before this (I was manually pausing/resuming during octopus sessions on the weekend)

Looked in the app this morning saw that timed charge was disabled so have re-enabled this. Hopefully fixes it for tonight.

Same here. Battery discharged to 0% and shutdown. Battery does restart OK. Octopus suggest unlinking battery and relinking battery to account - then charge - to be tested. No issues with panels or inverter

Mine is not linked to Octopus, just using GivEnergy App/Home Assistant.

Fine OK today after manually enabling it and predbat plan/app still showing that it will charge tomorrow

Did the Batts charge SteveL ?

Bridge47 sorry missed this. It's been working fine since then.

Just to close the loop here - this was my issue explained in the link. I can 100% recommend the company - they recovered my system quickly and expertly
