Audited Supplier The STS series by Guangdong Solarthon Technology Co., Ltd. is a cutting-edge solar storage inverter that combines solar energy storage, mains charging energy storage, and AC sine wave output. With its DSP control and advanced control algorithm, this inverter offers high response speed, reliability, and industrial standard.
Featuring four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power, the STS series allows for flexible selection of inverter and mains outputs to meet various application needs.
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 with a wide voltage range of MPPT.
The AC-DC charge module employs an advanced control algorithm for full digital double closed-loop control of voltage and current. With high control accuracy and a compact design, it provides stable and reliable charging and protection for the battery. Additionally, it offers a wide AC voltage input range and comprehensive input/output protection functions.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output pure sine wave and convert DC into AC. It is suitable for powering AC loads such as household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The product also features a segment LCD display for 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 Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits of English-speaking natives, ensuring a seamless experience for our customers.
Our inverters provide true pure sine wave output, guaranteeing high-quality power for your appliances. With a range of output options including 110V, 115V, 120V, 220V, 230V, and 240V, our inverters are self-adaptive to 50/60Hz frequency. If you have specific requirements, our engineers are available for consultation.
Choose our low frequency inverter for enhanced protection, adaptability, and reliability. With voltage regulation capabilities, it ensures a stable power supply. On the other hand, high frequency inverters are also available for different applications.
Opt for our pure sine wave output inverter for a power supply equivalent to the public power grid, or even better. With a low repair rate, long lifespan, and no harmonic pollution, it is environmentally friendly and ensures the protection of your appliances. In contrast, modified sine wave output may negatively impact certain appliances, especially those with inductive loads like air conditioners and refrigerators.
Our inverters are suitable for various applications, including household, office, and agricultural appliances. They can handle inductive loads such as refrigerators, air conditioners, water pumps, and more.
We offer the option to print your company logo on our inverters, nameplates, and packaging. Our OEM service ensures that you can customize the products to meet your specific branding needs.
Not sure which inverter is right for you? Simply share your requirements with our sales team, and they will recommend a suitable inverter based on your needs.
Our dedicated team provides 24-hour after-service consultancy to help you solve any technical problems you may encounter. We are committed to ensuring your satisfaction and making problem-solving easy for you.
While not absolutely required, a power inverter is essential for accessing 220 or 230 volts AC power. Without it, you would solely rely on battery power, which may not be sufficient for most users who want to use normal AC appliances.
Consider the input voltage from the battery bank when selecting an inverter. Higher voltages allow for smaller wires between your solar panel array and battery bank. It is crucial to ensure that the solar panels, inverter, and battery bank all use the same voltage.
In the unlikely event of a faulty product, simply send us pictures or videos, and we will study the issue. We provide free spare parts of PCB boards for after-sale service, ensuring your satisfaction and peace of mind.
