Thank you for your interest in our inverters. Here are some frequently asked questions and answers to help you understand our products:
Yes, all our inverters provide true pure sine wave output.
Our inverters are normally produced with self-adapting voltages of 110V, 115V, 120V, 220V, 230V, and 240V, with a frequency of 50/60Hz. If you have special requirements, please consult our engineers.
Low frequency inverters offer various protections, strong adaptability to different environments, and reliable voltage regulation. They are more reliable compared to high frequency inverters.
Pure sine wave output inverters provide power that is as good as the public power grid, if not better. They have a low repair rate, long lifespan, and do not cause harmonic pollution. They are also environmentally friendly and protect appliances. On the other hand, modified sine wave output inverters can have a negative impact on appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may not work well with modified sine wave inverters.
Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
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 access to 220 or 230 volts AC.
The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, which means you can use smaller wires between your solar panel array and battery bank. It's important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
If any product is faulty, please send us a picture or video, and we will study it and provide the necessary spare parts of the PCB board for after-sale service.
