Introducing the STS series, a revolutionary solar storage inverter from Guangdong Solarthon Technology Co., Ltd. This cutting-edge inverter combines solar energy storage, mains charging energy storage, and AC sine wave output, providing you with a reliable and efficient solution.
With its DSP control and advanced control algorithm, the STS series offers high response speed, exceptional reliability, and meets the highest industrial standards. It offers four charge modes to meet your specific needs: only solar power, mains power priority, solar power priority, and mains power & solar power. Additionally, you can select between inverter and mains outputs, ensuring maximum flexibility.
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 results in real-time optimization of solar panel energy output, even in challenging conditions. With a wide voltage range of MPPT, you can count on maximum energy production.
The AC-DC charge module employs an advanced control algorithm, offering full digital double closed-loop control of voltage and current. This ensures high control accuracy and a compact design. With a wide AC voltage input range and comprehensive input/output protection functions, your battery will be charged and protected reliably.
The DC-AC inverter module, based on a full digital intelligent design, uses advanced SPWM technology to output a pure sine wave. This makes it compatible with a wide range of 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 guarantees the safety and stability of the entire system.

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 and provide superior performance for a variety of applications.
Our inverters offer true pure sine wave output, ensuring reliable and high-quality power supply. With 110V, 115V, 120V, 220V, 230V, and 240V options, our inverters are self-adaptive to 50/60Hz frequency. If you have specific requirements, our engineers are available for consultation.
Our low frequency inverters are equipped with various protections, making them highly adaptable to different environments. They provide reliable performance, voltage regulation, and increased lifespan.
Our pure sine wave output inverters are comparable to the public power grid, if not better. They have a low repair rate, long lifespan, and do not cause harmonic pollution. Additionally, they are environmentally friendly and protect your appliances.
On the other hand, modified sine wave output inverters can negatively impact appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may also be incompatible with the modified wave.
Our inverters can be used in households, offices, and even with agricultural appliances. They are suitable for inductive loads such as refrigerators, air conditioners, water pumps, and more.
We accept OEM orders and can print your company logo on inverters, nameplates, and packaging, giving your products a personalized touch.
Simply tell us your requirements, and our sales team will recommend a suitable inverter that meets your needs.
We provide 24-hour after-service consultancy to help you solve any technical problems easily. Our dedicated team is here to support you.
While a power inverter is not absolutely required for a solar energy system, it is essential for accessing 220 or 230 volts AC and using normal AC appliances. Battery power alone may be sufficient for small RVs or cabins.
When choosing an inverter, consider the system voltage. Higher voltages allow for smaller wires between the solar panel array and battery bank. Ensure that the solar panels, inverter, and battery bank all use the same voltage.
If any product is faulty, simply send us a picture or video, and we will study the issue. We provide free spare parts for PCB board for after-sale service.
