Are your inverters pure sine wave output?
Q: Yes, all our inverters provide true pure sine wave output.
What kind of output can you provide?
Q: Normally, we produce inverters with self-adapting voltages of 110V, 115V, 120V, 220V, 230V, and 240V, operating at 50/60Hz. If you have any special requirements, please let us know for engineer consultation.
What's the difference between a low frequency and high frequency inverter?
Q: A low frequency inverter offers various protections, strong adaptability to different environments, and reliable voltage regulation. It is more reliable compared to a high frequency inverter.
What's the difference between a pure sine wave inverter and a modified sine wave inverter?
Q: A pure sine wave output inverter provides power that is just as good as the public power grid, if not better. It has a low repair rate, long lifespan, and does not cause harmonic pollution. It is also environmentally friendly and protects appliances. On the other hand, a modified sine wave output inverter can negatively impact appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may not be compatible with the modified wave.
What appliances can your inverters handle?
Q: Our inverters can be used with household, office, and agricultural appliances, as well as other inductive loads such as refrigerators, air conditioners, and water pumps.
Can you print our company logo on inverters, nameplates, and packaging?
Q: Yes, we accept OEM orders and can customize the inverters, nameplates, and packaging with your company logo.
How do I choose the right inverter?
Q: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
How do I solve technical problems?
Q: We provide 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Do I need a power inverter?
Q: Actually, a power inverter is not absolutely required for a solar energy system. However, without one, you will not have access to 220 or 230 volts AC and will solely rely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.
What's the difference between 12, 24, and 48 volt inverters?
Q: The voltage refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower currents, allowing for the use of smaller wires between the solar panel array and the battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage when deciding on a system voltage.
What should I do if the product is broken?
Q: If any product is faulty, you can send us pictures or videos, and we will analyze the issue. We will provide the necessary spare parts for the PCB board free of charge for after-sales service.
