Audited Supplier The STS series by Guangdong Solarthon Technology Co., Ltd. is a state-of-the-art solar storage inverter that combines solar energy storage, mains charging energy storage, and AC sine wave output. With its DSP control and advanced control algorithm, this inverter offers high response speed, reliability, and industrial standard.
Featuring four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power, the STS series is versatile and can be tailored to different application needs. The inverter and mains outputs are selectable, providing flexibility and convenience.
The solar charge module utilizes the latest optimized MPPT tracking technology, enabling it to quickly track the maximum power point of the PV array in any environment. This ensures that the solar panel obtains the maximum energy in real time, thanks to its wide voltage range of MPPT.
The AC-DC charge module incorporates an advanced control algorithm, allowing for full digital double closed-loop control of voltage and current. With high control accuracy and a compact design, this module provides stable and reliable charging and protection for the battery. It also offers a wide AC voltage input range and full input/output protection function.
The DC-AC inverter module, based on a full digital intelligent design, utilizes advanced SPWM technology to output pure sine wave and convert DC into AC. Perfect for AC loads such as household appliances, electric tools, industrial devices, and electronic audiovisual equipment.
The STS series features a segment LCD display design that shows real-time operation data and system status. Additionally, it offers comprehensive electronic protection functions to ensure the safety and stability of the entire system.

Are you in need of a reliable and efficient inverter for your power needs? Look no further than Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits and preferences of English-speaking natives, offering a seamless user experience.
Our inverters are built with pure sine wave output, ensuring a high-quality power supply comparable to the public power grid. With low repair rates, long lifespan, and no harmonic pollution, our inverters are not only reliable but also environmentally-friendly. Your appliances will be protected, and you'll enjoy a consistent and efficient power source.
Choosing between low frequency and high frequency inverters? Opt for our low frequency inverters that come with various protections and a strong ability to adapt to any environment. These inverters offer voltage regulation and are known for their reliability.
If you're wondering about the difference between pure sine wave and modified sine wave inverters, the answer is simple. Our pure sine wave output inverters are ideal for a range of appliances, providing a power supply equivalent to the public grid. On the other hand, modified sine wave inverters can have a negative impact on appliances and are not suitable for inductive loads such as air conditioners and refrigerators.
Our inverters are versatile and can be used in various settings, including households, offices, and agricultural environments. They are compatible with a range of appliances, including refrigerators, air conditioners, water pumps, and more.
We understand the importance of branding, which is why we offer OEM orders, allowing you to print your company logo on inverters, nameplates, and packaging. Additionally, our dedicated sales team is available to assist you in choosing the right inverter for your specific needs.
Should you encounter any technical issues, our 24-hour after-service consultancy team is here to help. We are committed to providing you with easy solutions and ensuring your satisfaction.
Not sure which inverter is right for you? Simply share your requirements with our sales team, and they will recommend the most suitable inverter for your needs.
While a power inverter is not absolutely required for a solar energy system, it is highly recommended if you want to use normal AC appliances. Without an inverter, you will only have battery power and no access to 220 or 230 volts AC.
When choosing an inverter, consider the input voltage from the battery bank. Higher voltages allow for less current, 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.
In the unlikely event that a product is faulty, simply send us a picture or video, and our team will study it. We provide free spare parts of the PCB board for after-sale service.
