I have an instalation where the daily peak loads cannot be served from the grid when power demand is higher than 600 Kw. So I was trying to configure a three phase quattro configuration + battery bank to serve the worst case150 Kw needed during 2 hours a day, to add the energy that loads demand during these hours. It is rather similar to peak shaving scenario.
My question is if there is possible to connect Inverter output in paralel to grid (provided 3 phase compensation). Reason is not to oversize inverters, just for the 2 hours where power assist should be needed
