These are the full complement of Power Jack inverters for the system I've been installing this past year. Taking good advice from all the great comments on my other previous videos (thanks guys!). Now I have four 80watt solar panels driving each 600W inverter (2S2P) 320 watts max, this is putting less stress on each inverter at times of inbalance. My peak power reading was over 2kW and on a good day the total power produced is averaging around 10kWh. My original setup had a timeswitch to save power at night, and now the inverters mains supply is switched on through a relay when the panels have enough daylight to start generating, they are then shut down again at dusk. After blowing two inverters while carrying out tests to the on/off set-points; this is now working fine, the inverters start and stop under stable supply conditions. I will soon add mains conditioning to each inverter as there is still a risk of power cuts blowing out the power FET's, as other Power Jack users can testify.
