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 for a reliable and efficient power solution.
With its DSP control and advanced control algorithm, the STS series offers high response speed, exceptional reliability, and meets high industrial standards. Choose from four charge modes: only solar power, mains power priority, solar power priority, or mains power & solar power. The inverter and mains outputs are selectable to meet 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 that the solar panel generates maximum energy in real-time, even with a wide voltage range of MPPT.
The AC-DC charge module features an advanced control algorithm, enabling full digital double closed-loop control of voltage and current. This results in precise control accuracy and a compact design. The module supports a wide AC voltage input range and provides full input/output protection, ensuring stable and reliable charging and protection of the battery.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave. This allows it to convert DC power into AC power, making it suitable for 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 ensures the safety and stability of the entire system.

Introducing our high-quality inverters from Guangdong Solarthon Technology Co., Ltd. These inverters are designed to meet the reading habits of English-speaking natives, providing a clear and concise understanding of their features and benefits.
Yes, all our inverters provide true pure sine wave output.
Our inverters are available in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V. They also feature self-adaption to 50/60Hz. If you have special requirements, please consult our engineers.
Low frequency inverters offer superior protection, adaptability, and voltage regulation compared to high frequency inverters. They are more reliable and suitable for a wide range of environments.
Pure sine wave output inverters provide power equivalent to the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. On the other hand, modified sine wave output inverters can negatively impact appliances and are not suitable for inductive loads such as air conditioners and refrigerators.
Our inverters are suitable for household, office, and agricultural appliances. They can handle inductive loads such as refrigerators, air conditioners, water pumps, and more.
Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
While not absolutely required, a power inverter is essential if you want to have 220 or 230 volts AC and use normal AC appliances. Without a power inverter, you will solely rely on battery power.
The voltage refers to the input voltage from the battery bank. Higher voltages allow for lower currents, enabling the use of smaller wires between the solar panel array and the battery bank. It's important to 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 it. We provide free spare parts of the PCB board for after-sale service.
