Are your inverters pure sine wave output?
Yes, All are true pure sine wave.
What kind of output you can do?
Normally we produce inverter with 110V 115V 120V 220V 230V 240V, 50/60Hz self-adaption. If you have special requirements, please tell us for engineer consulting.
What's the difference between low frequency and high frequency inverter?
Low frequency inverter has various protections, strong ability to adapt to the environment. more reliable, with voltage regulation.
What's the difference between pure sine wave inverter and modified sine wave inverter?
Pure sine wave output inverter is just as good as the Public power grid. Even better. Low repaired rate, long lifespan, Without harmonic pollution, environmental-friendly and appliances protected. Modified sine wave output has a negative impact on appliances and can't load inductive load, such as air condition, refrigerator and etc. Certain motor control circuits don't like the modified wave.
What appliances your inverters can load?
Our inverter can be used in household, Office, agricultural appliances and other inductive load such as refrigerator, air conditioner, water pump, etc.
What to do if the product is broken?
If any product is faulty, you can send the picture or video to us, we will study it and supply the spare parts of PCB board free for after sale service.
