Frequently Asked Questions (FAQ)

What core power components are used in these three-phase off-grid inverters?

These inverters utilize high-performance IGBT components from Mitsubishi company to ensure reliable power conversion, compact design, and maximum system stability.

What remote communication modes are supported by the system?

The system supports multiple communication interfaces, including RS485, Wifi, GPRS, and Ethernet using the Modbus RTU protocol, allowing flexible local and remote system monitoring.

Can I customize the bypass transfer time for my specific power requirements?

Yes. While the standard bypass transfer time is ≤40ms or ≤100ms depending on the model, we can customize a faster version with a transfer time of ≤4ms to suit sensitive load requirements.

What safety and protection features are integrated?

The inverters come with comprehensive warning and protection functions, including input reverse polarity protection, input under-voltage protection, output overload protection, output short circuit protection, and over-temperature (thermal) protection.

Are solar chargers or external generator ports supported?

Yes, solar chargers, AC chargers, and dedicated generator connection ports are optional configuration features available upon request for all models in this series.

How does operating at high altitudes affect these inverters?

The inverters are rated to work optimally at altitudes up to 2000 meters. For applications above 2000 meters, the rated output power should be appropriately reduced to ensure safe operation.
