Couldn't load pickup availability
Build a flexible off-grid power setup with a 4kW inverter that combines solar, utility, and battery power—and can run without a battery.
- Solar charging: The built-in 140A MPPT controller supports up to 5,600W of PV input across a 55–350Vdc MPPT range.
- Pure sine wave output: Get 120Vac output at 4kW, with 50/60Hz frequency and a 24Vdc battery input; battery mode allows 100V, 110V, or 120V AC selection.
- Custom power priorities: Select Only Solar, Solar First, or Mains & Solar charging, plus SBU or SUB output mode to suit your setup.
- Clear controls and protection: Use the 6.25-inch LCD and touch buttons to adjust settings, while overload, overtemperature, and output short-circuit protection help safeguard operation. Wi-Fi monitoring is optional.
