So, I am in the process of converting a school bus into an rv and its time to hook up solar panels.
I have 5 fiamm 12UMTX180FT telecom batteries that i happened upon that were in great shape for only 75 bucks a piece all of which were holding at 13.2-13.3v 983amp hrs at a c20 rate
anyway i have since purchases an EPSOLAR 40 amp mppt charge controller model no. Tracer4210A specs listed below
basically what my question is, is that i found a great deal on three 295 watt solar panels at 36v 885 watts. the specs for the controller say that its capable of handling a max of 520 watts on a 12v system (43 amps) but the input amperage from the solar panels would be about 25 amps at 36v. id like to have the extra wattage so i can charge at full power even in less than optimal conditions, provided that the controller wont fry because its connected to a bigger solar array than it can convert to 12v and 40 amps. will the controller blow or will it just only draw enough current to process the 43 amps thats its rated at. i know i should have gone to a 24v but i already had my 3000 watt inverter and that thing was expensive. thanks for the help guys
