Introducing the STS series, a revolutionary solar storage inverter by Guangdong Solarthon Technology Co., Ltd. This cutting-edge inverter combines solar energy storage, mains charging energy storage, and AC sine wave output, providing a comprehensive solution for all your energy needs.
With its DSP control and advanced control algorithm, the STS series offers unparalleled performance. It boasts high response speed, exceptional reliability, and meets the highest industrial standards.
The STS series features four charge modes to suit different applications: only solar power, mains power priority, solar power priority, and mains power & solar power. Additionally, you can select between inverter and mains outputs to cater to your specific requirements.
Equipped with the latest optimized MPPT tracking technology, the solar charge module can quickly track the maximum power point of the PV array in any environment. This ensures you obtain the maximum energy from your solar panels in real time, thanks to its wide voltage range of MPPT.
The AC-DC charge module utilizes an advanced control algorithm to achieve 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 your batteries. Furthermore, it supports a wide AC voltage input range and provides full input/output protection.
The DC-AC inverter module, based on a full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave. This makes it suitable for powering a wide range of AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The segment LCD display design allows you to monitor the operation data and system status in real time, ensuring safety and stability with its comprehensive electronic protection function.

A: Yes, all our inverters provide true pure sine wave output.
A: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V output options. These inverters have a self-adapting frequency of 50/60Hz. If you have special requirements, please consult our engineers.
A: Low frequency inverters offer various protections, strong environmental adaptability, and reliable voltage regulation. On the other hand, high frequency inverters lack these features.
A: Pure sine wave output inverters provide power similar to the public power grid, with low repair rates, long lifespan, no harmonic pollution, and environmental-friendly operation. Modified sine wave output inverters have a negative impact on appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may not work well with modified sine wave inverters.
A: Our inverters can be used with household, office, and agricultural appliances, including inductive loads such as refrigerators and air conditioners.
A: Yes, we accept OEM orders and can customize the products with your company logo.
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 problems 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 an inverter, you will only be able to use battery power.
A: 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 all components of your system, including the solar panels, inverter, and battery bank, use the same voltage.
A: If any product is faulty, simply send us a picture or video, and we will study it and provide the necessary spare parts for free as part of our after-sale service.
