Mitsubishi IGBTs serve as premium power components that guarantee high efficiency, superior thermal management, and reliable switching characteristics. This drastically reduces power losses, ensuring the inverter delivers maximum efficiency ≥ 90% and stable power output under heavy loads.
Yes. While the standard bypass transfer time is ≤40ms for the 10KW model and ≤100ms for larger models (20KW to 50KW), we offer customization services to decrease the transfer time to ≤4ms. This matches UPS performance standards, keeping critical loads running without interruptions.
All models support RS485, Wifi, GPRS, and Ethernet interfaces utilizing the Modbus RTU protocol. This allows seamless integration into remote monitoring systems, cloud servers, and local SCADA platforms for real-time diagnostics.
Yes, these three-phase off-grid inverters are equipped with a built-in copper isolation transformer. The isolation transformer protects sensitive electronic equipment from potential DC leaks, harmonics, and sudden grid surges by providing complete electrical isolation between DC and AC circuits.
The system comes with comprehensive protection mechanisms, including DC input reverse polarity protection, input under-voltage protection, output overload protection, output short circuit protection, and over-temperature (thermal) protection.
Yes. Internal solar controllers (MPPT/PWM), AC utility chargers, and automatic generator start/stop ports are optional add-ons. Users can easily customize the inverter system to support hybrid solar, utility, and generator inputs.
