Off-grid Beginner
Or perhaps I didnt size it correctly. We are off grid and have 20pc 195w panels with 345AH of LFP batteries. Now that its summer and the rainy season is here, we cant keep up with AC use in the campers on hot days where it can be cloudy. I am thinking the solution is to get another 5 panels in series should at least start pushing some decent amps to the batteries even with our inverter load.
I thought about getting larger, more economical panels but that would require another SCC and wires.
We cant really drop our inverter load since we have pets in the RV on 95F days while we are building the house.
My question is, for $1.2k i can get 5pc 195w panels like I have and mounting hardware. Alternatively, for about $100/ea I can get 280w panels. I already have a NIB midnight classic 250. I would just need wire to run from the panels to the classic 250. Id rather sell the classic 250 to recoup some cash. Would I be better off in the long run with 2 SCC for the different brand panels or should stick with the brand I have and just keep building on it? My PT100 SCC has room for more amps. I haven't seen over 40 amps with my current setup.
The batteries suggested charge current us 50A with max charge current 100A.
Trying to make the best decision.
Redundancy is very appealing..
