Product Description

 

Are you looking for a reliable inverter that meets the reading habits of English-speaking natives? Look no further! Introducing the inverters from Guangdong Solarthon Technology Co., Ltd.

 

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 you provide?

 

Our inverters are available in 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adaption feature for 50/60Hz. If you have special requirements, our engineers are available for consultation.

 

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

 

Low frequency inverters offer various protections, strong adaptability to the environment, and reliable voltage regulation. On the other hand, 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 quality equivalent to or even better than the public power grid. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. On the other hand, modified sine wave output inverters can negatively impact appliances and are not suitable for inductive loads such as air conditioners and refrigerators.

 

What appliances can your inverters load?

 

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

 

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 issues you may encounter.

 

Do I need a power inverter?

 

While a power inverter is not absolutely required for a solar energy system, it is necessary if you want to use normal AC appliances. Without an inverter, you will only have battery power.

 

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 lower currents, enabling the use of smaller wires between the solar panel array and the battery bank. It is 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, simply send us a picture or video, and we will study it and provide the necessary spare parts of the PCB board for free as part of our after-sale service.
