I have an all in one inverter with built in MPPT controller that I would like to test, but don't have a PV array available at the location where I am testing.
I do have a 30V, 10A power supply but my inverter is 48V and the minimum input voltage for the MPPT controller is 60V.
So could I connect my power supply in series with a 48V battery (not the one powering the inverter) and then use the combined voltage/current of the power supply/battery combo to test the controller? On paper it looks like that could work but anyone with real world experience know if this will work?
