FAQ

Product Description

 

Product Description

 

Thank you for your interest in our inverters. Below, you will find answers to some frequently asked questions:

 

Are your inverters pure sine wave output?

 

Yes, all our inverters provide true pure sine wave output.

 

What kind of output can your inverters provide?

 

Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adaption of 50/60Hz. If you have special requirements, please consult our engineers.

 

What's the difference between low frequency and high frequency inverters?

 

Low frequency inverters have various protections, a strong ability to adapt to the environment, and are more reliable. They also have voltage regulation capabilities. High frequency inverters lack these features.

 

What's the difference between pure sine wave and modified sine wave inverters?

 

Pure sine wave output inverters provide power similar to the public power grid, with low repair rates, long lifespan, and no harmonic pollution. They are environmentally friendly and protect appliances. On the other hand, modified sine wave output inverters have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits are also not compatible with modified sine wave inverters.

 

What appliances can your inverters load?

 

Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, and water pumps.

 

Can you print our company logo on inverters, nameplates, and packaging?

 

Yes, we accept OEM orders and can customize the products with your company logo.

 

How do I choose the right inverter?

 

Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.

 

How do I solve technical problems?

 

We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.

 

Do I need a power inverter?

 

While not absolutely required, a power inverter is necessary if you want to use normal AC appliances. Without an inverter, you will only have battery power and won't have access to 220 or 230 volts AC.

 

What's the difference between 12, 24, and 48 volt inverters?

 

The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, which means you can use smaller wires between your solar panel array and battery bank. It's important to ensure that the solar panels, inverter, and battery bank all use the same voltage.

 

What should I do if the product is broken?

 

If any product is faulty, please 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.
