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: only solar power, mains power priority, solar power priority, and mains power & solar power. Additionally, you can select between inverter and mains outputs, providing flexibility and versatility.
The solar charge module of the STS series utilizes the latest optimized MPPT tracking technology. This allows it to quickly track the maximum power point of the PV array in any environment, ensuring real-time maximum energy extraction from the solar panel. The MPPT has a wide voltage range, enhancing its efficiency and performance.
The AC-DC charge module of the STS series employs 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 offers comprehensive input/output protection, ensuring stable and reliable battery charging and protection.
The DC-AC inverter module of the STS series is based on a full digital intelligent design and utilizes advanced SPWM technology. It delivers a pure sine wave output, converting DC power into AC 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 provides real-time operation data and system status, while the comprehensive electronic protection function ensures the safety and stability of the entire system.

Are you in need of a reliable and efficient power inverter? Look no further than the inverters from Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits of English-speaking natives and provide a seamless experience.
Yes, all our inverters provide true pure sine wave output.
Our inverters typically produce output voltages of 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have specific requirements, our engineers are available for consultation.
Low frequency inverters offer various protections, strong adaptability to different environments, and reliable voltage regulation. On the other hand, high frequency inverters lack these features.
Pure sine wave inverters provide 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, especially inductive loads like air conditioners and refrigerators.
Our inverters are suitable for household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, and water pumps.
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 an inverter, you would solely rely on battery power, which may not be sufficient for most applications.
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 and provide the necessary spare parts of the PCB board for free as part of our after-sale service.
