The integrated MPPT controller simplifies system architecture by reducing external components, improving overall system efficiency and installation convenience. Wide PV and AC input ranges enhance system adaptability in diverse environmental and electrical conditions.
Battery compatibility across multiple chemistries allows optimized energy storage selection and long-term system scalability. Optional WiFi functionality supports both iOS and Android platforms, enabling remote monitoring and basic system management through mobile devices.


The inverter is engineered for stable operation in off-grid scenarios, supporting continuous energy supply for critical loads while maintaining consistent output performance.
The Off-Grid Inverter is designed for standalone solar power systems that operate independently from the utility grid. It integrates power conversion, solar charging, and energy management into a single unit, enabling reliable electricity supply in remote or off-grid environments.
The inverter features a built-in MPPT solar charger that continuously tracks the maximum power point of photovoltaic modules, improving solar energy utilization under varying irradiance conditions. A wide PV input voltage range allows flexible solar array configuration, supporting different panel layouts and system sizes.
With a wide AC input range, the inverter can adapt to unstable or variable generator input, ensuring continuous power supply when solar energy is insufficient. The system supports AGM, Gel, and Lithium battery types, enabling flexible energy storage configuration based on project requirements.
