November 4, 20241 yr For clarity - the yellow line is solar power, blue the load and red is mains For some unknown reason, my inverter randomly decides now is a good time to supply the load from the mains instead of from the batteries. It only happens when it starts getting cloudy and the clouds randomly gets in front of the sun. In this case, the batteries are full. My inverter's hybrid setting is set to "off" and the option to share the load between mains and solar is also off. In the example below, yesterday, I ran the microwave while there was not enough sun to supply the load and it worked fine. Does anyone have any ideas? This has me puzzled.
