Product Description:
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 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, strong adaptability to different environments, 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 equivalent to the public power grid, with low repair rates, long lifespan, no harmonic pollution, and environmental friendliness. On the other hand, modified sine wave output can negatively impact appliances and cannot handle inductive loads such as air conditioners and refrigerators. Certain motor control circuits may also be incompatible with modified sine wave output.
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 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 offer 24-hour after-service consultancy to help you solve any technical issues easily.
Q: Do I need a power inverter?
A: While not absolutely required, a power inverter is necessary if you want to have 220 or 230 volts AC and use normal AC appliances. Without a power inverter, you will solely rely on battery power, which may be acceptable for small RVs or cabins.
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 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, please send us pictures or videos for our assessment. We will provide free spare parts of the PCB board for after-sale service.
