Q: Are your inverters pure sine wave output?
A: Yes, all our inverters are true pure sine wave.
Q: What kind of output can you provide?
A: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adaption of 50/60Hz. 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 more reliability 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. Modified sine wave output, on the other hand, can have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits do not 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 and water pumps.
Q: Can you print our company logo on inverters, nameplates, and packaging?
A: Yes, we accept OEM orders and can customize the products with your company logo.
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 issues you may encounter.
Q: Do I need a power inverter?
A: Technically, no. A power inverter is not absolutely required for a solar energy system. However, if you don't use one, you will not have 220 or 230 volts AC and will have to rely solely on battery power. This might be acceptable in a small RV or cabin, but most people prefer to use normal AC appliances.
Q: What's the difference between 12, 24, and 48-volt inverters?
A: The voltage refers to the input voltage from the battery bank. The main consideration is that at higher voltages, the current is less, allowing you to 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 pictures or videos, and we will study the issue and provide free spare parts of PCB boards for after-sale service.
