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 high 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, 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. 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 full digital intelligent design, utilizes advanced SPWM technology to output pure sine wave power. This makes 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 safety and stability.

Welcome to Guangdong Solarthon Technology Co., Ltd.! We offer a range of high-quality inverters that are designed to meet your power needs. Read on to learn more about our products:
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 have a self-adaption feature for 50/60Hz. If you have specific requirements, our engineers are available for consultation.
Low frequency inverters offer various protections, adaptability to different environments, and reliable voltage regulation. On the other hand, high frequency inverters may not provide the same level of protection and adaptability.
Pure sine wave inverters produce output similar to the public power grid, with low repair rates, long lifespan, no harmonic pollution, and environmental friendliness. On the other hand, modified sine wave inverters can negatively impact appliances and are not suitable for inductive loads such as air conditioners and refrigerators.
Our inverters can be used with various appliances, including those in households, offices, and agricultural settings. They are also suitable for inductive loads such as refrigerators and air conditioners.
Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
Simply let us know 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 lower currents, which means you can use smaller wires between your solar panel array and 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 and provide the necessary spare parts of the PCB board for free as part of our after-sale service.
