Hi,
I want to test a SMA 4kW grid tie solar PV inverter under max load, or close to it at least. Initial thoughts are to get a 230/110V isolating transformer (about 5kA rating) & bridge rectify, then feed into the inverter PV inputs as full wave rectified DC.
I can't see why this wouldn't work, but I'm not confident about it. Does anyone have any thoughts? Would I need to smooth it?
Thanks.
