Growatt SPF 12000KT DVM-US — 12 kW Split-Phase Off-Grid Inverter/Charger

UL 1741 certified • 120/240 V true split-phase • Dual 120 A MPPTs • 36 kW surge

Take your off-grid or backup system to pro level with the Growatt SPF 12000KT DVM-US, a low-frequency, pure-sine inverter that bundles a high-power transformer, dual solar MPPTs, and a 120 A generator/utility charger into one rugged, UL-listed package. Built for cabins, whole-home backup, small farms, and light-commercial sites that demand rock-solid 120/240 V power, this all-in-one unit drives heavy loads while keeping batteries topped up from solar or genset automatically.

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.
