So recently, when I have the grid plugged in-which is rare unless it is cloudy and I want to charge by both solar and grid, and stay relatively/fully charged—When the AC300 reaches 100% the AC power sometimes recycles and the ac inverter turns off and immediately back on. This is very confusing because it should not turn on or off when fully charged. I have recycled the batteries in the past/every 6-months as the manual states, and when i purchased the newest battery, but this is recent. The last drain was 2.5 months ago ±
Is there something up because it has not done this before.
My most recent purchase was the B300k(my 4th battery) but that was 10/31/25
My app states that I am up to date on updates.
