fuse and wire sizing
Hi Everyone, so I’ve committed to my equipment list for my off grid solar setup and now I need to figure out wiring and fusing. What I will have is 4 to 5 310 watt(37V, 8.38A) panels wired into two or three strings of two panels a piece and maybe the fifth one by itself. I need to know how best to combine, fuse and what wire gauge to use for the panels before they hit the Midnite Classic charge controller. From there it will need to be fused again going to my 24V 430AH battery bank and then after through another fuse to the inverter. I would assume 2 AWG would be fine for running from charge controller to batteries and from batteries to inverter but I don’t know how to determine the amps of the battery bank based on the AH. The charge controller will probably be about 10’ away from the battery bank and the Inverter should be around 3’ away. I have the AC portion figured out, I just need to figure out the DC.
