I too have decided to use Will Prowse’s “Off Grid King” system. The reason for using 24V to the others is that we are limited on money. We have a 36’ 5th wheel that was mobile but is stationary now so weight and size isn’t an issue any longer. I’d like a 48V system but not switching now. At the time we decided that the 24V met all our needs and we can even add on later. We want this system to supply energy for our a/c 6.5A fridge, 12V water pump and 12V lights. Later we can add more panels and batteries to hopefully run an A/C window unit(s). We don’t need microwave, small appliances or tools. So, here’s what we have. I loaded pictures of my layout but just so you know, I haven’t cut most of the wires yet. I have 6awg for the charge controllers to breakers and then bus bars, also 6awg going to the panels. 2awg to most everything else except the ground wire(12awg), 12V-24V converter is 12awg, and from the battery monitor shunt (18awg) to positive bus bar at battery. When I ordered the bus bars I didn’t know that they were rated so what I have is 250amps. Do I need another size or are these ok? If I’m making any mistakes would you please offer advice for me to correct them. Also, do I need a battery disconnect? I have circuit breakers (50A) from the charge controllers and then more to my panels, but is this correct? Let me know if I’ve missed anything and I’ll post it ASAP. THANKS in advance
