Off‑Grid Solar Power Kit | MPPT Controller + LFP Battery + Off‑Grid Inverter
The GreenMore Off-Grid Solar Power Kit is a fully integrated renewable energy solution combining a 3KW/5KW pure sine wave inverter, MPPT solar charge controller, LiFePO₄ battery pack and smart BMS in one compact unit. Built with fully digital dual closed-loop control and SPWM technology, it delivers clean, stable AC power for residential, commercial and mission-critical loads. The system supports AC/PV priority charging, hybrid modes and automatic battery activation, making off-grid deployment straightforward.
The kit also works as a UPS with seamless switchover, protecting sensitive equipment during power interruptions. Multi-layer protection covers overcharge, over-discharge, short circuit and temperature extremes, with intelligent air cooling for quiet indoor operation. Available in two standard configurations, 5.12kWh and 10.24kWh. Certified with CE, IEC, MSDS and UN38.3. 3-year warranty.

Inverter, MPPT controller, LFP battery pack and BMS arrive in one unit. No separate sourcing or complex wiring — installation and commissioning are noticeably faster for installers.
Fully digital dual closed-loop control with SPWM output gives peak efficiency above 90% and AC voltage distortion under 3% — safe for medical devices, servers and smart home systems.
Mains bypass and inverter modes run with full-power UPS function. When grid power fails, the system transfers to battery automatically, keeping refrigerators, lighting and communication gear running.
6,000+ cycles at 80% DOD support 15+ years of daily use, with real-time cell monitoring from the smart BMS and deep-discharge capability.
AC/PV priority, PV-only and hybrid charging modes, plus generator input — the kit adapts to fully off-grid sites and regions with unreliable supply alike.
Temperature-controlled fans keep noise below 55dB indoors, with multi-layer electrical protection and CE, IEC, MSDS and UN38.3 certification.
High-efficiency MPPT tracking maximizes PV harvest, with priority/hybrid charging logic and built-in overvoltage and over-temperature protection.
Fully digital dual closed-loop control with SPWM pure sine wave AC and full-power UPS mode for sensitive electronics.
Lithium-only architecture with smart activation, long cycle life, deep-discharge capability and an optimized charging curve.
Real-time monitoring of voltage, current, SOC and temperature, with OVP/OCP/SCP/OTP protection and coordinated inverter control.
Integrated circuit breakers and surge protection handle priority switching and hybrid charging, keeping the load supply stable.
LCD/APP display of live system status, configurable charging and UPS settings, plus fault alarms and logs for maintenance.
