Audited Supplier Introducing the STS series, a revolutionary solar storage inverter brought to you by Guangdong Solarthon Technology Co., Ltd. This cutting-edge inverter seamlessly integrates solar energy storage, mains charging energy storage, and AC sine wave output.
With its DSP control and advanced control algorithm, the STS series offers unparalleled response speed, reliability, and industrial standard. It features four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power. Additionally, the inverter and mains outputs are selectable, catering to various application needs.
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 real-time maximum energy extraction from the solar panel, thanks to its wide voltage range of MPPT.
The AC-DC charge module employs an advanced control algorithm, enabling full digital double closed-loop control of voltage and current. This results in high control accuracy and a compact design. The battery can be stably and reliably charged and protected, thanks to its wide AC voltage input range and comprehensive input/output protection function.
The DC-AC inverter module, based on a full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave, effectively converting DC into AC. It is perfectly suited for powering AC loads such as household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The product also features a segment LCD display, providing real-time operation data and system status. With its comprehensive electronic protection function, the STS series ensures 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 the inverters from Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits of English-speaking natives and provide a seamless experience.
Our inverters offer a true pure sine wave output, ensuring high-quality power that is just as good as the public power grid. With low repair rates and a long lifespan, our inverters are reliable and environmentally friendly. They do not cause harmonic pollution and provide protection for your appliances.
Our low frequency inverters are equipped with various protections and have a strong ability to adapt to different environments. They also offer voltage regulation, making them more reliable. On the other hand, high frequency inverters do not offer the same level of protection and adaptability.
Our pure sine wave output inverters provide power that is equivalent to the public power grid, if not better. They have a low repair rate, a long lifespan, and do not cause harmonic pollution. In contrast, modified sine wave output inverters can have a negative impact on appliances and are not suitable for loading inductive loads such as air conditioners and refrigerators.
Our inverters can be used in various settings, including households, offices, and agricultural environments. They are suitable for powering appliances such as refrigerators, air conditioners, and water pumps.
If you want to customize our inverters with your company logo, nameplates, or packaging, we accept OEM orders.
Tell us your power requirements, and our sales team will recommend a suitable inverter for you.
We offer 24-hour after-service consultancy to help you solve any technical problems you may encounter with our inverters.
While a power inverter is not absolutely required for a solar energy system, it is essential if you want to use normal AC appliances. Without an inverter, you will only have battery power.
The voltage of our inverters can be 12, 24, or 48 volts. The choice depends on your battery bank's input voltage. Using higher voltages allows for smaller wires between your solar panel array and battery bank.
If any of our products are faulty, simply send us a picture or video, and we will provide free spare parts of the PCB board for after-sale service.
