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 generation 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. The module also 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 features a segment LCD display for real-time operation data and system status. Additionally, it incorporates comprehensive electronic protection functions to ensure the safety and stability of the entire system.

Are you in need of a reliable and efficient power inverter? Look no further than Guangdong Solarthon Technology Co., Ltd. We offer a wide range of pure sine wave inverters that are designed to meet the reading habits of English-speaking natives.
A: Yes, all our inverters provide true pure sine wave output.
A: Normally, we produce inverters with self-adapting voltages of 110V, 115V, 120V, 220V, 230V, and 240V, operating at 50/60Hz. If you have specific requirements, our engineers are available for consultation.
A: 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.
A: 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. In contrast, modified sine wave output inverters can negatively impact appliances and are not suitable for inductive loads such as air conditioners and refrigerators.
A: Our inverters are suitable for household, office, and agricultural appliances, as well as inductive loads like refrigerators and water pumps.
A: Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
A: We offer 24-hour after-service consultancy to help you easily solve any technical issues you may encounter.
A: 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.
A: The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, enabling the use of smaller wires between the solar panel array and the battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
A: If any product is faulty, simply send us a picture or video, and we will study it. We provide free spare parts of PCB boards for after-sale service.
