Unbox, wheel in, plug in, done.
A complete power plant in one cabinet: our 3.5kVA hybrid inverter and a 7,987Wh LiFePO4 battery arrive pre-matched and pre-wired on swivel wheels. Connect PV, grid and loads to the labeled terminals and the system runs — solar-priority allocation, seamless grid fallback and an LCD keeping you informed.
Inverter and battery are engineered as one system — no compatibility risk, no cable sizing, one warranty.
The system prioritizes PV supply and charging, using grid only to fill gaps — and switches between them in under 10ms.
Swivel casters and plug-and-play terminals mean installation is positioning, not construction. Sleep mode cuts standby drain when idle.
Battery, load and PV parameters stream over RS485 to the display or your monitoring platform.

Essential household loads for a full day-plus: refrigerator, lighting, router, TV and a washing machine cycle, with 3.5kVA of concurrent output — plus solar recharge extending runtime indefinitely.
Standard charge at 40A takes about 10 hours; fast charge at 60A shortens it, and the 4,000W MPPT can fully recharge the pack from solar in one good sunny day.
