FAQ

Why would you need a 3-phase frequency inverter?

A 3-phase inverter is typically used in applications where three-phase power is required or preferred due to its efficiency and performance advantages.

Industrial and commercial applications: Many industrial and commercial facilities use three-phase power for running heavy machinery, motors, and equipment. Three-phase power provides a more balanced and efficient power supply for such high-demand applications.
Higher power requirements: Three-phase systems can handle higher power loads more effectively than single-phase systems. This is beneficial for operations that require substantial power input, such as manufacturing plants, large HVAC systems, and certain types of electrical motors.
Improved efficiency: Three-phase power systems are more efficient in transmitting and using electrical power. They reduce the amount of electrical loss in the system, leading to better overall efficiency and lower operating costs.
Stable and reliable power supply: Three-phase systems provide a more stable and continuous power supply, which is essential for sensitive equipment and applications that cannot afford interruptions or fluctuations in power.
Solar and renewable energy systems: In larger solar PV installations and wind turbine systems, three-phase variable frequency inverters are often used to convert DC power generated by the panels or turbines into three-phase AC power. This can then be used on-site or fed into the grid, taking advantage of the efficiency and stability of three-phase power.
Electric vehicles and charging stations: Some electric vehicle charging stations and certain high-power electric vehicle applications use three-phase frequency drive inverters to provide faster and more efficient charging.

Good customer service

I start the device and the inverter cannot be used. There are still many problems with the inverter itself, so I raised these questions via email. I received great answers and solutions quickly, and I gave them a thumbs up for their good customer service!
