Audited Supplier Introducing the STS series, a cutting-edge solar storage inverter developed by Guangdong Solarthon Technology Co., Ltd. This innovative inverter seamlessly integrates solar energy storage, mains charging energy storage, and AC sine wave output. With its advanced DSP control and control algorithm, the STS series offers exceptional response speed, reliability, and industrial standard.
The STS series features four charge modes to cater to different application needs. Choose from only solar power, mains power priority, solar power priority, or mains power & solar power. Additionally, the inverter and mains outputs are selectable, providing flexibility and versatility.
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 real-time maximum energy extraction from the solar panel, even with a 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. With high control accuracy and a compact design, it offers stable and reliable charging and protection for the battery. The wide AC voltage input range and comprehensive input/output protection function further enhance its performance.
The DC-AC inverter module, based on a full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave. This allows it to efficiently convert DC into AC, 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 design provides real-time operation data and system status, while the comprehensive electronic protection function ensures the safety and stability of the entire system.

Thank you for your interest in our inverters. Here are some frequently asked questions and answers to help you understand our products:
Yes, all our inverters provide true pure sine wave output.
Our inverters normally produce output with voltages of 110V, 115V, 120V, 220V, 230V, and 240V. They also have a self-adaption feature for 50/60Hz. If you have special requirements, please consult our engineers.
Low frequency inverters have various protections and a strong ability to adapt to different environments. They are more reliable and have voltage regulation capabilities.
Pure sine wave output inverters provide power that is as good as the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. They also protect appliances. On the other hand, modified sine wave output inverters can have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may not work well with modified sine wave inverters.
Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
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 provide 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
While a power inverter is not absolutely required for a solar energy system, it is necessary if you want to use normal AC appliances. Without a power inverter, you will only have battery power and not 220 or 230 volts AC.
The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, which means you can use smaller wires between your solar panel array and battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
If any product is faulty, please send us a picture or video. We will study it and provide the necessary spare parts of the PCB board for free as part of our after-sale service.
