Company Information





Q1: What' s the difference between low frequency and high frequency inverter?

A1: Low frequency inverter has various protections, strong ability to adapt to the environment. more reliable, with voltage regulation.

Q2: What's the difference between pure sine wave inverter and modified sine wave inverter?

A2: Pure sine wave output is the same as the AC government power output. 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.

Q3: What kind of output you can do?

A3: Normally, we produce inverter with 110v/ 50Hz, 120V/ 60Hz, 220v/ 50Hz, 230v/ 50Hz, 240V/50Hz.

If you have special requirements, pls tell us for engineer consulting.

Q4: What appliances your inverters can load?

A4: Our inverter can load household appliances other inductive load such as refrigerator, air condition, water pump, etc.

Q5: What is the warranty for your products?

A5: For the inverter, controller and battery, we have 1 year warranty. For the solar panel, we have 10 years warranty. If any problems on our side occured during warranty time, we will be responsible for that.

Q6: What's your products lifespan?

A6: Usually, for inverter and battery, lifespan is 3-5 years. for solar panels, over 20 years, However,  if you keep good maintenance for them, It will be longer and longer.
