Introducing the STS series, a cutting-edge solar storage inverter by Guangdong Solarthon Technology Co., Ltd. This innovative inverter combines solar energy storage, mains charging energy storage, and AC sine wave output, providing a reliable and efficient solution for your energy needs.
With its DSP control and advanced control algorithm, the STS series offers high response speed, exceptional reliability, and meets the highest industrial standards. It features four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power, allowing you to select the most suitable mode for your specific application.
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 that you can harness the maximum energy from your solar panels in real-time, thanks to its wide voltage range of MPPT.
The AC-DC charge module incorporates an advanced control algorithm, enabling full digital double closed-loop control of voltage and current. This results in high control accuracy and a compact design. The wide AC voltage input range and full input/output protection function ensure stable and reliable charging and protection of the battery.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave, converting DC into AC. This makes it suitable for powering AC loads such as 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 offer a range of features and benefits that are sure to impress.
Our inverters provide a true pure sine wave output, ensuring a high-quality and stable power supply. With voltage options of 110V, 115V, 120V, 220V, 230V, and 240V, our inverters are self-adaptive to 50/60Hz frequencies. If you have specific requirements, our engineers are available for consultation.
Our low frequency inverters offer various protections and have a strong ability to adapt to different environments. They are highly reliable and feature voltage regulation. On the other hand, high frequency inverters may not offer the same level of protection and adaptability.
Our pure sine wave output inverters provide power that is equivalent to the public power grid, if not better. They have a low repair rate, long lifespan, and do not cause harmonic pollution. They are also environmentally-friendly and protect your appliances. In contrast, modified sine wave output inverters can negatively impact appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may not be compatible with modified sine wave output.
Our inverters can be used with a variety of appliances, making them suitable for household, office, and agricultural use. They can handle inductive loads such as refrigerators, air conditioners, water pumps, and more.
We accept OEM orders and can print your company logo on our inverters, nameplates, and packaging. This allows you to customize the products to your brand's specifications.
If you're unsure which inverter is right for your needs, simply let us know your requirements and our sales team will recommend a suitable option for you.
We offer 24-hour after-service consultancy to help you solve any technical problems you may encounter. Our goal is to make problem-solving easy for you.
While a power inverter is not absolutely required for a solar energy system, it is highly recommended if you want to use normal AC appliances. Without an inverter, you will only have battery power and not have access to 220 or 230 volts AC.
The voltage of your inverter should match the voltage of your 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 your solar panels, inverter, and battery bank all use the same voltage.
If any of our products are faulty, simply send us a picture or video and we will study the issue. We provide free spare parts of PCB boards for after-sale service.
