Key reasons installers love it
-
Real split-phase output (120 V / 240 V) — runs everything from kitchen appliances to 240 V well pumps without an external autotransformer.
-
Massive 36 kW (3×) surge for 10 ms — starts compressors, air-conditioners, and motor loads without brownouts.
-
Dual MPPTs, 120 A total — connect mixed-orientation PV strings (up to 150 V DC each) and harvest every watt, even at dawn or in partial shade.
-
120 A low-frequency AC charger — rapid battery recovery from a generator or the grid; perfect for cloudy stretches.
-
48 V battery platform — pair with today’s popular LiFePO₄ racks or large lead-acid banks for up to 600 A continuous discharge.
-
Comprehensive protections — overload, short-circuit, reverse-polarity, high-temperature, and deep-discharge safeguards keep your investment safe.
-
Configurable input priority — choose Solar-first, AC-first, or Generator-assist via the integrated LCD.
-
Remote monitoring ready — add the optional WiFi/GPRS dongle for cloud performance tracking, alerts, and firmware updates.
-
UL 1741 & FCC compliant — meets North-American safety standards for peace of mind and easy inspection sign-off.
