Need info on MPPT/charge controllers able to output up to 500A at 48Vdc. High-voltage DC input (up to 300Vdc) preferred. Units will connect to a 20-24 kW PV array and 150 kW-h battery for a large off-grid system. Not locked into 48Vdc. Can go up to 108Vdc (nominal) if needed.
Any such CC units available? If not, what's been the collective Wrench experience in paralleling multiple controllers of whatever max output amperage exists on the market? I realize a paralleled configuration of this nature would entail multiple separate arrays in use on the input. That won't be a problem. Just need to be able to feed the common battery bank. Thanks. Dan
