So, grid is disconnected, battery is turned off and both PV arrays show 0A and around 470v.... where is the energy coming from to support the load?


It is a sunny day and both PV arrays show good V but 0A.

From solar plus battery.

Those meters aren't that accurate. If the solar panel is supplying .38 amps then it can cover that 1.5 amp load at 120 volts - and .38 amps may be below its minimum resolution (.5 amps?)

Help me out to understand that.

The log shows active power of the load a bit below 500w, but Solar total panel power 50-100w. No grid no batt. How that works??

None of my AIO's report an accurate power from the panels. Put a DC clamp meter on PV incoming line and also measure PV voltage at the terminals. W=VA
 
Ok. So basically inaccurate inverter readings, margin of error is higher the lower you go. Understood.
