Hello Forum. I am new to the forum and new to solar.
I recently set up a small off grid solar power system to provide the basics for our 240 sq ft cabin. SET UP: 2 Canadian Solar 215W 24V panels wired in series; 2 Canadian Solar 250W 24V panels wired in series (930W total). Each solar panel string runs to its own Midnight Solar 20 amp breaker contained in a Midnight Solar Combiner Box. I split the din rail in the combiner box to run each pv string positive separately. All pv negatives run to the negative buss bar in the combiner box. Each pv string has its own EPSolar 40amp MPPT charge controller, and both charge controller charges 4 Rolls S-605's in series parallel to make a 12v system (900+Ah).
I am just looking for any assistance/opinion on my system set up. The cabin is tiny, so a 12v system is fine for our needs. However, I wonder if the set up is efficient.....and whether the system is sufficient to charge the batteries. Is there a better configuration I should consider. Any advice is greatly appreciated.
Power Needs: 5 cu ft freezer converter to a fridge with a Johnson's Control; a small new bar fridge; 12v water pump; 4 led lights; and a 600W microwave (used for 2 mins couple times a week during daylight).
I live in Nova Scotia, Canada.
