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 the environment, and reliable 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 quality similar to the public power grid, with low repair rates, long lifespan, no harmonic pollution, and environmental-friendly operation. On the other hand, modified sine wave output inverters may negatively impact appliances and cannot load inductive loads like air conditioners and refrigerators. Certain motor control circuits may also not be compatible with the modified wave.
Q: What appliances can your inverters support?
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 customize the inverters with our company logo?
A: Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
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 with the inverter?
A: We provide 24-hour after-service consultancy to help you easily solve any technical issues.
Q: Do I need a power inverter?
A: Technically, no. A power inverter is not absolutely required in a solar energy system. However, without a power inverter, you will not have 220 or 230 volts AC and will have to rely solely on battery power. While this might be acceptable in 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: The voltage refers to the input voltage from the battery bank. Higher voltages allow for lower currents, enabling the use of smaller wires between the solar panel array and the battery bank. It's important to note that when choosing 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, simply send us pictures or videos, and we will study the issue and provide the necessary spare parts of the PCB board for after-sale service.
