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: We normally produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have any 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 and have a strong ability to adapt to different environments. They are more reliable and have 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 quality equivalent to or even better than the public power grid. They have a low repair rate, long lifespan, and are free from harmonic pollution, making them environmentally friendly and ensuring the protection of appliances. On the other hand, modified sine wave output inverters can have a negative impact on appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may not be compatible with the modified wave.
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 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 offer 24-hour after-service consultancy to assist you in solving any technical issues easily.
Q: Do I need a power inverter?
A: While a power inverter is not absolutely required in a solar energy system, it is essential if you want to use normal AC appliances. Without a power inverter, you will only have battery power and not 220 or 230 volts AC. This may be acceptable for small RVs or cabins, but most people prefer to use 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 result in lower current, allowing you to use smaller wires between your solar panel array and battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage when deciding on a system 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 analysis. We will provide the necessary spare parts of the PCB board free of charge for after-sale service.
