A: Yes, all our inverters provide true pure sine wave output.

A: Yes, all our inverters provide true pure sine wave output.

A: Low frequency inverters have various protections, strong adaptability to the environment, and are more reliable with voltage regulation.

A: Pure sine wave output inverters provide power quality equivalent to or better than the public power grid. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. Modified sine wave output inverters have a negative impact on appliances and cannot load inductive loads, such as air conditioners and refrigerators. Certain motor control circuits may not be compatible with modified sine wave inverters.

A: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.

A: Yes, we accept OEM orders and can customize the products with your company logo.

A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.

A: We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.

A: While a power inverter is not absolutely required for a solar energy system, it is necessary if you want to use normal AC appliances. Without a power inverter, you will only have battery power and won’t have 220 or 230 volts AC. This may be acceptable for small RVs or cabins.

A: If any product is faulty, please send us a picture or video, and we will study it. We provide free spare parts of the PCB board for after-sale service.
