Are your inverters pure sine wave output?
Q: Yes, all our inverters provide true pure sine wave output.
A: What kind of output can you provide?
Q: Normally, we produce inverters with self-adapting 110V, 115V, 120V, 220V, 230V, and 240V outputs at 50/60Hz. If you have special requirements, please let us know for engineer consultation.
A: What's the difference between a low frequency and high frequency inverter?
Q: A low frequency inverter offers various protections, strong adaptability to the environment, and higher reliability with voltage regulation.
A: What's the difference between a pure sine wave inverter and a modified sine wave inverter?
Q: A pure sine wave output inverter is comparable to the public power grid, if not better. It has a low repair rate, long lifespan, no harmonic pollution, and is environmentally friendly while protecting appliances. On the other hand, a modified sine wave output can negatively impact appliances and cannot handle inductive loads such as air conditioners and refrigerators. Certain motor control circuits are also not compatible with the modified wave.
A: What appliances can your inverters handle?
Q: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
A: Can you print our company logo on inverters, nameplates, and packaging?
Q: Yes, we accept OEM orders.
A: How do I choose the right inverter?
Q: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
A: How can I solve technical problems?
Q: We provide 24-hour after-service consultancy to help you easily solve any technical problems.
A: Do I need a power inverter?
Q: Actually, no. A power inverter is not absolutely required for a solar energy system. However, without one, you won't have 220 or 230 volts AC and will solely rely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.
A: What's the difference between 12, 24, and 48 volt inverters?
Q: The voltage refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower currents, allowing for the use of smaller wires between the solar panel array and the battery bank. When deciding on a system voltage, it's important for the solar panels, inverter, and battery bank to all use the same voltage.
A: What should I do if the product is broken?
Q: If any product is faulty, you can send us pictures or videos, and we will study them and provide free spare parts for the PCB board as part of our after-sale service.
