[RE-wrenches] Trace SW 4048

[Rick Brown]

Marco,

Can you be more specific when you say not producing PV power? Do you mean no AC output? Given that these are battery-based inverters they’re not dependent on the PV to be present in order to operate. What state are the batteries in? Is the voltage stable when the inverter is in invert mode?
