The inverters feature Mitsubishi IGBT modules as the key power components and American Atmel microprocessors as the digital controllers to ensure high performance and reliable operation.
The standard bypass transfer time is ≤40ms for the 10KW model and ≤100ms for models from 20KW to 50KW. A faster version of ≤4ms can be customized upon request.
The inverters support RS485, Wifi, GPRS, and Ethernet communication interfaces utilizing the standard Modbus RTU protocol for remote system management and monitoring.
No, the AC charger, solar charger, and generator ports are optional, customizable functions that can be added according to specific application demands.
The systems provide extensive protection mechanisms including DC input reverse polarity protection, DC input under-voltage protection, AC output overload protection, AC output short-circuit protection, and over-temperature (thermal) protection.
Yes, these inverters deliver a pure sine wave output equipped with a built-in copper isolation transformer, keeping total harmonic distortion (THD) under 3% for linear loads.
