I've got most of my solar and electrical setup all hooked up, and I'll be finishing it this weekend once I get the proper fuses / breakers and make the last connections. This part gets confusing pretty easily so I was hoping somebody might be able to help me figure out what I need for my setup.
Here's what I got.
4x 245 watt solar panels. 2 in series, 2 in series, then paralleled together. (imp: Current at Max Power (7.6A))
40A mppt charge controller
9x nissan leaf battery modules (3 groups of 3 in series for 24v, wired in parallel for 24v battery bank)
24v 3000w inverter / charger
24 volt to 12 volt converter
30A shore plug
6 bay load center
24volt LED lights
12volt roof vent/fan
12volt water pump
I know I'll need a 30A breaker between shore power and inverter/charger
I have my breakers in the load center already wired up (20a and 15a, depending on circuit, not all of them being used but may add later)
I'll have a 12v fuse box for those 2 loads
Planned on wiring 24v LED right to the batteries with a small fuse (switches inline up front) as it's my only thing needing 24v, but I'm not sure if I should just wire those to the output of the charge controller
What i need help figuring out is the proper size fuses/breakers to put in between -
solar panels - charge controller (20A circuit breaker with disconnect option?)
charge controller - battery bank (unsure)
inverter / charger - load center (unsure)
battery bank - inverter charger (charging output current of inv/ch is 50a, so 60amp fuse/breaker?
battery bank - 24v/12v converter (converter is rated 40A, so i assumed 40a fuse/breaker)
Also, am I missing anything or is that everything I'll need?
attached is a rough sketch of my setup, and the couple pictures i took of some of the stuff
in advance. Any help is much appreciated.
