I am currently not at home, and the AIO Battery has shown rapid drop in battery charge status, several times, with no obvious increase in power utilisation
My Battery is 13.5 KW, I Wouldn’t expect the background power utilisation in an empty house, to deplete the battery to 4% and start charging during the expensive part of the day.
My normal utilisation when I am home is in the region of 40%, so why is vacant house utilisation varying between 20% and 75%
I think you’ll have to look at the house load - the Giv inverter will no doubt have a clamp monitoring that. It’s possible for the battery SOC to adjust, but that sounds too high - more like something is drawing power. Check the house load in the portal
If I was able to leave pictures, I Would have included an image showing no appreciable difference between house load, before the questionable reduction in battery capacity and during the period of concern.
If the battery state of charge needs re calibrating frequently, there must be something wrong with the system.
this is almost definitely the cause of your problem. If you keep your battery in a narrow SoC range then the battery can loose track of how much is actually stored in it.
The power didn’t discharge, it was never there, and what you saw was the inverter correcting for how much charge it realises that it actually has
You don’t need to recalibrate the battery, but what you do need to do is ensure you are on the latest firmware for your AIO, and regularly (every week or so) ensure your battery gets discharged fully and recharged fully. This should solve your problem. It is quite common.
