I am running into confusing information about solar chargers. I have room for 10(15 if I get creative) 450-watt solar panels on my roof. each with an open circuit voltage of 47v and an expectation of about 10 amps real-world output. looking at chargers for a 12v system nothing makes financial sense. Victron's biggest is 250/100, which maxes out of about 1100w charging on a 12v system. I would need 5 $1000 controllers..... I am hoping I am doing some math wrong. On the small end however the 100/50 can do 700 watts and I could do one per panel and only come out at around $1500 total (10 chargers).
My goal would be 2 banks of 5 panels as that's how they will be arranged on the roof and while they will be adjustable when parked if one side is shaded I don't want the whole system to suffer.
currently looking at the Canadian Solar BiHiKu CS3W-450MB-AG as I can get them cheap $300/each shipped. but am open to suggestions to get the most out of the system.
the roof is 9.5ft by 36ft of usable space. no restrictions. I have low-profile ACs and will be building a rack above everything with linear actuators for tilt control.
The inverter is the MultiPlus-II 2x 120V and currently, I have 1000AH of usable storage.
