Kortsluiting reacted to PsyWulf in New Kodak installationVoltage based guestimation doesn't work very exact when those batteries have a sudden voltage drop when applying load
Also there's usually an inherent leech involved even with no loads

I’m not familiar with the batteries but I see that they mention monitoring via an app that connects via Bluetooth to the battery. I would check the battery SOC using that app instead of the WatchTower app to be certain that you getting the correct SOC.

Kortsluiting reacted to Coulomb in New Kodak installationI don't see a cable between the inverter (equivalent to an Axpert VM III, I believe) and the battery. So the inverter is guessing the battery SoC based on its voltage. For LFP, this is totally inadequate. As you've seen, it makes a different guess depending on whether the mains is on.
Just ignore what the inverter says about the state of charge of the battery.
