So have a setup thats not changed since last spring. Suddenly I'm showing it's drawing from the battery to feed back into the grid, middle of the night so no PV. VRM has it using about 33% of the battery then recharging from the grid. I have no AC loads (protected sub-panel breaker is off for the winter) and about 50w of DC thats pretty much venus and the network. I am getting ve.bus low battery warnings and alarms while it's doing this (graphing never shows under 60%).
Any ideas? I could turn off feedback for the winter as I'm maybe at break even but this could be problematic in summer.
