FAQ

Q: Do you support OEM/ODM and what is the MOQ?

A: Yes. OEM/ODM includes logo customization, firmware adjustment, and monitoring platform customization.
MOQ depends on customization requirements and order structure.

Q: Can this inverter work in unstable grid or off-grid areas?

A: Yes. The inverter is designed to operate in both stable and unstable grid environments, and it can switch between grid-connected and off-grid modes automatically to maintain continuous power supply for connected loads.

Q: What type of loads can this inverter support?

A: It is suitable for both resistive loads (lighting, electronics) and inductive loads (pumps, air conditioners, compressors), thanks to its high surge capacity of up to 2× rated power for 10 seconds.

Q: Does it require external protection devices during installation?

A: The inverter already includes multiple built-in protection functions such as overvoltage, short circuit, surge protection, and insulation monitoring. However, external protection devices may still be required depending on local electrical regulations.

Q: What maintenance is required during operation?

A: The inverter is designed for low-maintenance operation. Regular inspection of wiring connections, ventilation conditions, and dust accumulation is recommended depending on installation environment.

Q: Can firmware be updated after installation?

A: Yes. The inverter supports remote firmware updates, allowing performance optimization and feature upgrades without physical access to the unit.
