1. 4000W ALL-IN-ONE PURE SINE WAVE SYSTEM – Converts 24V DC into stable 120V AC pure sine wave power, delivering 4,000 watts of continuous output and 8,000 watts of surge capacity. It combines an inverter, solar charge controller, AC battery charger, and automatic source-transfer control in one unit.

2. BUILT-IN 140A MPPT SOLAR CONTROLLER – Supports up to 5,600W of solar input, a maximum PV open-circuit voltage of 350V DC, up to 20A of PV input current, and a recommended PV operating range of 90–280V DC, eliminating the need for a separate solar charge controller.

3. SOLAR, BATTERY, AND UTILITY POWER SUPPORT – Operates from solar panels, a 24V battery bank, or utility/generator AC input based on the selected priority settings. Supports up to 140A of solar charging, 110A of AC charging, and 140A of combined solar-plus-AC charging. Compatible with common 24V AGM, gel, flooded lead-acid, lithium-ion, and LiFePO4 battery systems.

4. IDEAL FOR OFF-GRID AND ESSENTIAL BACKUP POWER – For routine use, keep the combined continuous load at or below 3,200W. Suitable for refrigerators, freezers, microwaves, coffee makers, lights, TVs, routers, fans, small water pumps, and power tools. Designed for off-grid cabins, RV solar systems, garages, workshops, and essential home backup loads.

5. PROGRAMMABLE POWER MANAGEMENT – The LCD control panel allows users to configure output priority, charging priority, charging current, output voltage, frequency, and battery-protection settings. Three temperature-controlled cooling fans support extended operation. Battery-free daytime operation is available when solar input is sufficient, but a 24V battery bank is strongly recommended for nighttime use, cloudy conditions, and high-startup loads. Install properly sized breakers on the PV, battery, AC input, and AC output circuits, and have the system installed by a qualified professional.
