Frequently Asked Questions

What are the primary components used in these three-phase off-grid inverters?

Our three-phase off-grid inverters use high-quality IGBT modules from Mitsubishi as the power components, alongside microprocessors from ATMEL as the digital controller, ensuring high stability, efficiency, and reliability.

Can the bypass transfer time be customized?

Yes. While the standard bypass transfer time is ≤40ms or ≤100ms depending on the specific model, we offer custom configurations to reduce this transfer time to ≤4ms for sensitive equipment.

What communication protocols and options are supported?

The inverters support multiple communication options including RS485, WiFi, GPRS, and Ethernet, utilizing the standard Modbus RTU protocol for convenient remote monitoring and data configuration.

What is the output waveform and efficiency of the inverter?

The system outputs a pure sine wave through an integrated copper isolation transformer. The maximum system efficiency reaches ≥90%, with specific inverter efficiency rated up to 94%.

How does altitude affect the output power of the inverter?

The standard rated parameters apply to altitudes below 2000 meters. For operations above 2000 meters, output power should be derated appropriately to ensure safe and stable thermal operation.

What built-in protection features are included?

The inverters include comprehensive protection mechanisms such as DC input reverse polarity protection, input under-voltage protection, output overload protection, output short circuit protection, and thermal over-temperature protection.
