Are your inverters pure sine wave output?
Q: Yes, all our inverters are true pure sine wave.
A: What kind of output can you provide?
Q: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please let us know for engineer consulting.
A: What's the difference between low frequency and high frequency inverters?
Q: Low frequency inverters have various protections and a strong ability to adapt to the environment. They are more reliable and have voltage regulation.
A: What's the difference between pure sine wave inverters and modified sine wave inverters?
Q: Pure sine wave output inverters are just as good as the public power grid, if not 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 sine wave.
A: What appliances can your inverters load?
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 do I solve technical problems?
Q: We offer 24-hour after-service consultancy to make it easy for you to 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, if you don't use one, you will not have 220 or 230 volts AC and will have to rely solely on battery power. This might be acceptable in a small RV or cabin, but most people prefer to use normal AC appliances.
A: What's the difference between 12, 24, and 48 volt inverters?
Q: This refers to the input voltage from the battery bank. The main consideration is that at higher voltages, the current is less, allowing you to use smaller wires between your solar panel array and your battery bank. When deciding on a system voltage, the solar panels, inverter, and battery bank all need to 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 the necessary spare parts of the PCB board for after-sale service.
