Q: Are your inverters pure sine wave output?
A: Yes, all our inverters are true pure sine wave.
Q: What kind of output can your inverters provide?
A: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with 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, a strong ability to adapt to the environment, 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 are just as good as the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally-friendly while protecting appliances. On the other hand, modified sine wave output has a negative impact on appliances and can't load inductive loads, such as air conditioners and refrigerators. Certain motor control circuits don't work well with modified sine waves.
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, air conditioners, water pumps, etc.
Q: Can you print our company logo on inverters, nameplates, and packaging?
A: Yes, we accept OEM orders.
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 provide 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Q: Do I need a power inverter?
A: Actually, no. The power inverter is not absolutely required for a solar energy system. However, without one, you will not have 220 or 230 volts AC and will have to rely solely on battery power. While this might be acceptable for a small RV or cabin, most people prefer to use normal AC appliances.
Q: What's the difference between 12, 24, and 48 volt inverters?
A: This refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower current, allowing for the use of smaller wires between the solar panel array and the battery bank. When deciding on a system voltage, all components, including the solar panels, inverter, and battery bank, need to use the same voltage.
Q: What should I do if the product is broken?
A: If any product is faulty, you can send us pictures or videos, and we will study the issue and provide the necessary spare parts for the PCB board free of charge for after-sale service.
