Spoofing Multigate to make microinverters run


New Member
I have found several sources for the SMA 240 solar microinverters, but none for the Multigate that is needed to run them. Has anyone experimented with these (less than $30 each) to create an input to "spoof" the control unit? I suspect a signal generator fed into the 240V line would do it, but have no idea what Hz and waveform.
