I have 2 14kwh batteries and the solar panels powering the 12kw inverter. I've given up trying to figure out what's going on and am instead putting a dedicated battery to power the hair dryer, then it recharges slowly so there is no spike from the hair dryer.

I'm not sure which side is blown, but there is ac input and nothing output. I will take one apart to see, but either way, the thing stops working without blowing the 2A breaker. My thought was that the voltage droops and the regulator on the PCB demands more current to maintain power and...

VOC is around 40V, so 10 panels is less than the 500V limit on the inverter. I have not updated the firmware. I didn't know I had to do that. I'll do that ASAP, thanks.

I agree this is what it sounds like. But what is the solution? There doesn't seem to be a way to control how the inverter deals with low PV power. My "whole setup" is really simple. 10X 370 watt panels in series going into the PV1 input on the 18KPV, two PowerPro batteries in parallel going...

10X 370 watt PV panels, 18KPV, 2X Powerpro batteries, totally off grid. Battery state of charge ~70%. When the sun is coming up in the morning and the solar panels are putting out less than 100 watts, the inverter shows that it is charging the batteries and sending power to the house. When...
