Product Q&A

Q:Are your inverters pure sine wave output?
A:
Yes, All are true pure sine wave.
Q:What kind of output you can do?
A:
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.
Q:What's the difference between low frequency and high frequency inverter?
A:
Low frequency inverter has various protections, strong ability to adapt to the environment. more reliable, with voltage regulation.
Q:What's the difference between pure sine wave inverter and modified sine wave inverter?
A:
Pure sine wave output inverter is just as good as the Public power grid. Even better. Low repaired rate, long lifespan, Without harmonic pollution, enviromental-friendly and appliances protected. Modified sine wave output has a negative impact on appliances and can't load inductive load, such as air contition, refrigerator and etc. Certain motor control circuits don't like the modified wave.
Q:What appliances your inverters can load?
A:
Our inverter can be used in household, Office, agricultural appliances and other inductive load such as refrigerator, air conditioner, water pump, etc.
