This three-phase off-grid inverter uses high-quality IGBT modules from Mitsubishi as the core power components to ensure high stability, durability, and superior power conversion performance.
The controller relies on an advanced microprocessor from ATmel (USA) as the digital figure controller, which coordinates the electrical systems precisely and provides quick response speeds.
The inverter supports multiple communication modes, including RS485, Wifi, GPRS, and Ethernet using the standard Modbus RTU protocol, allowing easy remote monitoring and system configuration.
It outputs a clean Pure Sine Wave through an integrated isolation copper transformer. The Total Harmonic Distortion (THD) is kept under 3% under linear loads, ensuring safe operation for sensitive appliances.
The inverter comes built with perfect protection functions, including input reverse polarity protection, input under-voltage protection, output overload protection, output short circuit protection, and thermal/overheating protection.
Yes, it features optional integration capacities for a solar charger, an AC charger, and a dedicated generator port to accommodate different hybrid power setup requirements.
