Frequently Asked Questions (FAQ)

What are the primary component brands used in these off-grid inverters?

Our three-phase off-grid inverters utilize high-quality Mitsubishi IGBT modules as the power components and American ATMEL microprocessors as system figure controllers to guarantee stability and high operational efficiency.

What is the transfer switching speed for the AC bypass?

The standard bypass transfer time is ≤40ms for the 10KW model, and ≤100ms for models from 20KW to 50KW. A customized high-speed version with a transfer time of ≤4ms can also be produced upon request.

What communication protocols and options are supported?

The system supports RS485, Wifi, GPRS, and Ethernet communications using the standard Modbus RTU protocol, allowing users to remotely monitor and control parameters via mobile apps or computer software.

What safety and protection features are integrated?

Each inverter comes with built-in protections against input reverse polarity, DC under-voltage, output overload, output short-circuits, and over-temperature safety shutdown mechanisms.

Does the inverter output pure sine wave?

Yes, all model variants produce a clean pure sine wave output through built-in heavy-duty copper isolation transformers, making them highly compatible with inductive loads like motors, pumps, and industrial appliances.

Can these inverters operate with external generators?

Yes, we provide an optional generator dry contact port that allows the inverter to automatically control and start backup diesel generators when battery banks reach low voltage.
