Like this one https://www.ebay.co.uk/itm/600W-MPPT-Micro-Solar-Inverter-Grid-Inverter-DC22V-60V-to-AC-230V-50Hz-60Hz-UK81/253569254624?hash=item3b09e7c4e0:g:rR0AAOSwNSZa1yHT
My only real concern would be testing the islanding and I think that could be done by plugging it via a power meter like this https://www.ebay.co.uk/itm/Plug-in-Energy-Monitor-Power-Meter-Electricity-Kwh-Watt-Usage-Monitoring-Socket/273181428287?hash=item3f9ae1ca3f:g:s4EAAOSwiUpa4rvy
Then unplugging the power meter from the grid (not the grid tie) and checking it immediatly displays zero volts.
Does that sound like a good idea ?
Any experiences anyone ?
