Wrenches, William I did a few back up systems for data hubs, we had 250+ kWhr systems. We had to have a firewall between the batteries and everything else. We used copper stock 1/2 x 2" and 20' long, each bank connected to the buss with its own 250 a breaker, the buss was above the batteries mounte

Dear Mike, As co-author of upcoming book "The Handbook of Solar Water Pumping", we have expanded its definition to include micro and national grid-tied systems in which pumping is synchronized with power availability from PV. I had known about frequency-based load control for microgrids (from a
