Hey everyone, I have a MPP LV2424 that has been working well on 2x310W panels. Looking to expand the solar array. I found a good deal on some 250W panels. The manual says recommended is 2S4P, which seems reasonable but needs some big wires for the expected 34A (my solar array and inverter won't be too close, maybe 150').
So I'm looking at 3S2P as an alternative (maybe 3P, just looked into the overpaneling resource, guess that's a separate question), which would be V_oc of 112.2V at STC. I'm in Colorado where it gets cold. The MPP LV2424 manual states the MPPT range is 30-115V. What happens over that range? Calculated voltage would be 121.7 at 0C, 125.6V at -10C and so on. Would the inverter just pull whatever it can from the current voltage? Would that then pull the voltage down into the MPPT range?
Can the MPP inverters handle overpaneling? That would be sizing the solar array for more than the rated amps and the controller just uses up to maximum amps?
