Bench testing Enphase microinverters

jjackstone · 11-08-18, 04:00 PM

Checked the search engine and didn't see a thread for this. Has anyone here figured out a simple way to bench test microinverters? I'm sure a battery or power supply could be connected as a DC input, but from what I understand, there must be a line signal too or they won't work at all. Any ideas on how to simulate an ac signal with enough amplitude to activate the inverter? I would guess it also checks for line frequency. Also as far as I know all the Enphase inverters are 240 volts AC output so that might have to be taken into account.
