The SCC-MPPT 3KW takes up to 3200W of PV array. The string has to stay below 145VDC open-circuit — that ceiling is reached on a cold bright morning, not at noon.
It is published for sealed lead-acid batteries. Charge voltages differ between chemistries, so a bank of another type is not a drop-in swap.
Up to 20A. Size the cable and the protection between the unit and the bank on that figure, not on the average you expect to see.
