Advice on Current Solar System Setup Design
I’m wondering if someone can give advice on my setup. Does everything seem sufficient and safe?
300w Renogy panel.
I have two LiFePo 12 v batteries: wired with a BMS as 2s4p. BMS has a discharge of 60amp and a charge current of 30amp.
I’m using these bus bars: https://www.amazon.com/dp/B0915GWDJ9?psc=1&ref=ppx_yo2ov_dt_b_product_details. I’m getting these tomorrow and can take pictures of everything wired up once I get them.
I have 4/0 wire going from batteries to busbar with an off-switch and a 200 amp windy nation ANL fuse..
I have an AIMS 1000W/2000W surge (seems like it came with 2 gauge wire, but I have some extra 4/0, do you think I should use it here?). I have a 120 amp blue sea 285 series circuit breaker from inverter to busbar.
I have a 40amp mppt Renogy charge controller that will have 6gauge wire going to busbar.
I have 6 gauge wire going from bus bar to 12v blue sea fuse box for 12v appliances. I have a 75 amp circuit breaker (taiwanese) that I got from the person I bought the batteries from, though it seems like I would want something rated for lower amps for my setup, no?
These are my 12v appliances:
-maxx air fan (med: .8 amp; high 2.8 amp)
-water pump (7.5 Amps )
-dometic fridge 80cu (7amp/12 v)
-starter for chinese diesel heater
-led lights (3w)
-mounted fan (1w)
I’m thinking about installing a dc to dc. Renogy 40amp.
