I recently had to fix a similar issue with a dual SI site. No blown Capacitor, but blank screens regardless of power cycles, and good voltages in and out. Took the covers off and notice a red led illuminated on the bottom left corner of the main circuit board next to the electro-mechanical

William Here is the deal it will be simplest to go AC for the pump because of the requirement of high voltage DC yes there are small er output DC pumps but that is not what you need, first find a AC pump that can do the required 10 GPM at 300 feet of head then design a inverter to fit that bill PV

Friends: I have a client that wishes to pump water at about 10 GPM from spring through autumn equinoxes. Lift is 300 feet. (This is the project that will not siphon beyond 33 feet.) I can design a solar/battery/inverter system for this purpose but I am wondering if there is a direct DC
