Introducing the STS series, a cutting-edge solar storage inverter from Guangdong Solarthon Technology Co., Ltd. This innovative inverter combines solar energy storage, mains charging energy storage, and AC sine wave output. With its DSP control and advanced control algorithm, the STS series offers exceptional response speed, reliability, and industrial standard.
The STS series features four charge modes to suit different application needs: only solar power, mains power priority, solar power priority, and mains power & solar power. You can select between inverter and mains outputs, providing flexibility and versatility.
The solar charge module utilizes the latest optimized MPPT tracking technology, allowing it to quickly track the maximum power point of the PV array in any environment. This ensures you can obtain the maximum energy from your solar panels in real time, thanks to its wide voltage range of MPPT.
The AC-DC charge module employs an advanced control algorithm for full digital double closed-loop control of voltage and current. With high control accuracy and a compact design, it offers stable and reliable charging and protection for your batteries. The wide AC voltage input range and full input/output protection function further enhance its performance.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output pure sine wave and convert DC into AC. It is suitable for powering various AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The segment LCD display provides real-time operation data and system status, while the comprehensive electronic protection function ensures safety and stability.

Introducing our pure sine wave inverters from Guangdong Solarthon Technology Co., Ltd. These inverters are designed to meet the reading habits of English-speaking natives, providing a reliable and efficient power solution for various applications.
Our inverters produce a true pure sine wave output, ensuring high-quality power that is just as good as the public power grid. With a low repair rate and long lifespan, these inverters offer a reliable and durable solution for your power needs. They are also environmentally-friendly, without any harmonic pollution, and provide protection for your appliances.
Our inverters come in different output options, including 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have specific requirements, our engineers are available for consultation to ensure the right inverter for your needs.
Our low frequency inverters offer various protections and have a strong ability to adapt to different environments. They are more reliable and feature voltage regulation. On the other hand, high frequency inverters may not offer the same level of protection and adaptability.
Our pure sine wave output inverters provide power that is equivalent to or even better than the public power grid. They have a low repair rate, long lifespan, and do not cause harmonic pollution. In contrast, modified sine wave output inverters can negatively impact appliances and are not suitable for inductive loads such as air conditioners and refrigerators.
Our inverters can be used in various settings, including households, offices, and agricultural applications. They are suitable for powering inductive loads such as refrigerators, air conditioners, and water pumps.
We offer the option to customize our inverters with your company logo. We accept OEM orders to meet your specific branding needs.
Our sales team is available to assist you in choosing the right inverter for your requirements. Simply provide us with your demand, and we will recommend a suitable inverter for you.
We provide 24-hour after-service consultancy to help you solve any technical problems you may encounter. Our goal is to make problem-solving easy and efficient for you.
While not absolutely required, a power inverter is essential for accessing 220 or 230 volts AC power. Without an inverter, you would solely rely on battery power, which may not be sufficient for most applications.
The voltage of your inverter should match the voltage of your battery bank. Higher voltages allow for lower currents, enabling the use of smaller wires between your solar panel array and battery bank. It is crucial to ensure that your solar panels, inverter, and battery bank all operate at the same voltage.
If any product is found to be faulty, simply send us a picture or video, and we will study the issue. We provide free spare parts of PCB boards for after-sale service.
