Key Features & Technical Advantages
Unmatched Surge Power capability: The low-frequency transformer core delivers massive surge power (2-3 times the rated power),
effortlessly starting and running high-induction loads like central
air conditioning units, water pumps, and power tools that would stall conventional inverters.
True Hybrid Functionality: Intelligently manages and prioritizes multiple power sources. It
uses solar energy as the primary source, supplements with grid/generator power when
needed, and provides seamless backup power during outages, all while efficiently charging the battery bank.
Industrial-Grade Pure Sine Wave Output: Generates a perfectly clean and stable pure sine wave, ensuring the safe and efficient operation of the most sensitive
electronics, medical equipment, and variable-speed appliances.
High-Capacity MPPT Solar Charger: Includes a high-amp MPPT (Maximum Power Point Tracking) solar charge controller optimized for large solar panel arrays, maximizing energy harvest and significantly reducing battery
recharge times.
Powerful Dual AC Input & Charger: Features a built-in high-current battery charger (via grid or
generator) and often supports dual AC inputs for added flexibility,
allowing connection to both the main grid and a backup generator.
Advanced Compatibility & Monitoring: Fully compatible with lithium (LiFePO4), AGM, GEL, and flooded batteries. Comes with a remote monitoring panel or
app support for real-time system management, configuration, and
fault diagnosis.
Application Scenarios
This high-power inverter series is built for the most demanding
energy needs:
Whole-House & Cabin Off-Grid Systems: Acts as the central power unit for entire off-grid homes, cabins,
