Converts 24 V battery power to 3500 W pure sine wave AC with a built-in 100 A MPPT controller accepting 60–500 V DC input
This 2-in-1 unit combines a pure sine wave inverter with an MPPT solar charge controller for off-grid photovoltaic systems. It delivers 3500W of continuous AC power at 220/230V and suits installations using 24V lead-acid, lithium or LiFePO4 battery banks. The integrated design reduces wiring complexity for remote cabins, backup power or mobile applications.
The built-in MPPT controller accepts a PV array voltage range of 60 to 500V DC and can charge the battery bank at up to 100A from solar or combined solar and AC sources. Conversion efficiency reaches 94 percent, and the unit handles a maximum PV input power of 4000W. AC-only charging is limited to 80A, so grid-assisted charging is slower than solar peak potential.
The inverter switches to battery power in 10 milliseconds when configured in UPS mode, protecting sensitive electronics during grid outages. In standard appliance mode the transfer takes 20 milliseconds, which may reset some equipment. No-load consumption is 35W, so the system draws measurable power even when idle.

The inverter switches to battery power in 10 ms in UPS mode, fast enough to keep most 24V lead-acid systems running without interruption.
Connect the supplied WiFi antenna and monitor real-time PV voltage, charging current and battery state of charge through the companion app or the on-screen display.
The MPPT controller is built into the inverter; the box contains the hybrid unit, one WiFi antenna and a user manual — no extra controller purchase is needed.
