Hello, I new to solar and sorry in advance for the questions coming!
We have a 48V battery bank, four 12V 80 amp/h, 800 CCA, batteries in series. We have the Cosuper 3000W, 48V charger/inverter, 60amp mppt controller. Currently have six 100w, 18V, 5.5 amps solar panels currently set up in 2 banks of 3 for perfect world of 54V and 11 amps going to the solar charger. This is for an off grid system, which we have generator power for, and the inverter is also able to charge the batteries when needed. (our current needs are around 1.5Kw - 2.2 Kw but plan on expanding in future with more panels) So here comes my questions:
1: The inverter manual is bad, so I can't find what input voltage would work best on setting up our panels. The batteries and inverter/charger are 48v, so I am assuming we need more then 54V for input to the charger and it will bring that voltage down 48v and increase amps for charging batteries. But what would my best set up be, all six in series, 3 banks of 2?
2: We also have another 150w panel, no hooked up and plan on getting a second 150w panel. Becuase this panel is 12v and 12.5 amps, different from out 100w panels. Can we hook either one or both of these up to our current inverter/charger and what set up could we use? Or would be need another solar charger for these since they are difference voltage amps? I know if we hooked up with the 100w, which ever set up had lower amps, is what the system would put out and we would loose that power. So I might answer my own question and say we need another controller for these, but any help on how you can wire two solar chargers together when one of ours is the inverter/charger in one. So has our batteries and solar panels both connect right to the chrager/inverter, where in line would our second solar charger go?
3: We also would like to put in two battery monitors, one to measure what our solar is putting out, and one to tell us what our batteries are getting. Where would these be wired in line? Thanks for any help.
