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, 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 offer various protections, a strong ability to adapt to the environment, and more reliability. They also come with voltage regulation capabilities.
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 negatively impact appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may also not be compatible with modified wave inverters.
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 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 can 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: Technically, no. A power inverter is not absolutely required in 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. While this may be acceptable for small RVs or cabins, 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 higher voltages allow for lower currents, which means you can use smaller wires between your solar panel array and your battery bank. It's important to note that when deciding on a system voltage, the solar panels, inverter, and battery bank must all 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 assess the issue. We provide free spare parts of PCB boards for after-sale service.
