8kva Inverter not using battery when there is no PV power
My system have been working fine for almost 2years!
After a 2 week holiday, we noticed that the battery SOC is always above 90 percent, and the inverteris taking the power from the grid!
Any Ideas as to what the problem can be? There is no faults and no changes was made to any setting!

You have a problem with the battery, As you can see on LiBMS page it is limiting discharge current to 8A.
I would start by turning it off and on, if that doesn't help, it is warranty time.
