This three-phase off-grid inverter incorporates Mitsubishi IGBT modules as the primary power components and utilizes an American ATEMEL microprocessor as the figure controller, ensuring high efficiency, reliability, and robust performance.
The inverter outputs a pure sine wave via an isolation copper transformer. It features a compact design with a maximum efficiency of 94% (or ≥ 90% for specific configurations) and low total harmonic distortion (THD ≤ 3% under linear load).
The system supports multiple communication protocols and interfaces, including RS485, Wifi, GPRS, and Ethernet, utilizing the standard Modbus RTU protocol for remote monitoring and integration.
Yes. The standard bypass transfer time is ≤ 40ms for the 10KW model and ≤ 100ms for models 20KW and above. An optional, fast-acting version of ≤ 4ms can be customized according to your application requirements.
It features a comprehensive protection suite, including DC input reverse polarity protection, DC input under-voltage protection, AC output overload protection, AC output short-circuit protection, and internal over-temperature (thermal) protection.
Yes, solar chargers, AC chargers, and dedicated generator ports are optional and available. You can customize the configurations to construct hybrid wind, solar, or battery storage systems.
