SunGoldPower's SPH6548P is a 48V all-in-one with two MPPT solar inputs, a 140A battery charger and 6500W of split-phase 120V/240V output. The maker states UL 1741 by ETL for off-grid use. It is part of a home's electrical system: a licensed electrician must install it under NEC and local permits, with DC cabling and fusing per the manual.
