Company Information



Welcome to Solarthon Technology Co., Ltd.

Are you in need of a reliable and efficient inverter for your power needs? Look no further! Our inverters are designed to provide you with a pure sine wave output, just like the power grid. With a low repair rate and long lifespan, our inverters are built to last.

But what sets our inverters apart from the rest? Well, let us tell you! Our low frequency inverters offer various protections and have a strong ability to adapt to any environment. They are more reliable and come with voltage regulation, ensuring that your appliances are always protected.

Now, you might be wondering about the difference between pure sine wave and modified sine wave inverters. Pure sine wave output inverters are not only as good as the public power grid, but even better! They have a low repair rate, long lifespan, and are environmentally friendly with no harmonic pollution. On the other hand, modified sine wave output can have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators.

Speaking of appliances, our inverters can handle a wide range of them. Whether it's for household, office, or agricultural use, our inverters can handle it all. From refrigerators to air conditioners and water pumps, you can rely on our inverters to power your appliances.

And if you're looking to add a personal touch to your inverters, we've got you covered! We accept OEM orders, so you can have your company logo printed on the inverters, nameplates, and packaging.

Choosing the right inverter can be a daunting task, but don't worry, our sales team is here to help. Just let us know your requirements, and we'll recommend a suitable inverter for you.

Now, let's talk about technical problems. We understand that they can be frustrating, but we're here to make it easy for you. Our 24-hour after-service consultancy is dedicated to solving your technical problems quickly and efficiently.

Now, you might be wondering if you really need a power inverter. While it's not absolutely required for a solar energy system, it's highly recommended if you want to use normal AC appliances. Without a power inverter, you'll be limited to using battery power alone.

When it comes to choosing the right voltage for your inverter, it's important to consider the input voltage from the battery bank. Higher voltages allow for smaller wires between your solar panel array and battery bank. Just make sure that your solar panels, inverter, and battery bank all use the same voltage.

Lastly, if any of our products are faulty, don't worry. Just send us a picture or video, and we'll study it and provide the necessary spare parts for our after-sale service.
