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 with our engineers.
Q: What's the difference between low frequency and high-frequency inverters?
A: Low-frequency inverters have various protections, strong adaptability 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 as good as the public power grid, even better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. They also protect appliances. On the other hand, modified sine wave output has 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 wave inverters.
Q: What appliances can your inverters handle?
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 can 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.
Q: Do I need a power inverter?
A: Actually, 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 solely rely 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 higher voltages allow for less current, enabling the use of smaller wires between the solar panel array and the battery bank. When deciding on a system voltage, the solar panels, inverter, and battery bank all 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 spare parts of PCB boards for free as part of our after-sale service.
