Q: Are your inverters pure sine wave output?
A: Yes, all our inverters provide true pure sine wave output.
Q: What kind of output can your inverters provide?
A: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please consult our engineers.
Q: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters have various protections, strong adaptability to different environments, and are more reliable with voltage regulation.
Q: What's the difference between pure sine wave inverters and modified sine wave inverters?
A: Pure sine wave output inverters provide power similar to the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally-friendly. On the other hand, modified sine wave output inverters can have a negative impact on certain appliances and are not suitable for inductive loads like air conditioners and refrigerators.
Q: What appliances can your inverters load?
A: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators and air conditioners.
Q: Can you print our company logo on the inverters, nameplates, and packaging?
A: Yes, we accept OEM orders and can include your company logo on our products.
Q: How do I choose the right inverter?
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
Q: How do I solve technical problems?
A: We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Q: Do I need a power inverter?
A: While not absolutely required, a power inverter is necessary if you want to use normal AC appliances. Without one, you will only have battery power and won't have 220 or 230 volts AC.
Q: What's the difference between 12, 24, and 48 volt inverters?
A: 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.
Q: What should I do if the product is broken?
A: If any product is faulty, simply send us a picture or video, and we will study it and provide the necessary spare parts of the PCB board for our after-sale service.
