ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW
Introducing the STS series, a cutting-edge solar storage inverter designed 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. It features four charge modes: solar power only, mains power priority, solar power priority, and mains power & solar power. This flexibility allows you to select the most suitable mode for your specific application needs.
The solar charge module incorporates 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 obtain the maximum energy from your solar panel 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. This results in high control accuracy and a compact design. The module supports a wide AC voltage input range and offers full input/output protection, ensuring stable and reliable charging and protection of the battery.
The DC-AC inverter module, based on a full digital intelligent design, employs advanced SPWM technology to output a pure sine wave. This makes it suitable for powering various AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The product features a segment LCD display that provides real-time operation data and system status. Additionally, the comprehensive electronic protection function guarantees the safety and stability of the entire system.

Product Description
Guangdong Solarthon Technology Co., Ltd. offers a range of high-quality inverters that are perfect for your power needs. Whether you need to power household appliances, office equipment, or agricultural machinery, our inverters are designed to deliver reliable and efficient performance.
Key Features:
- Pure Sine Wave Output: Our inverters provide a true pure sine wave output, ensuring the same level of quality as the public power grid.
- Wide Voltage Range: We offer inverters with 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 vs. High Frequency: Our low frequency inverters offer various protections, adaptability to different environments, and reliable voltage regulation. On the other hand, high frequency inverters may have limitations and are not suitable for certain appliances.
- Pure Sine Wave vs. Modified Sine Wave: Our pure sine wave inverters provide numerous benefits, including low repair rates, long lifespan, absence of harmonic pollution, and protection for your appliances. In contrast, modified sine wave inverters can negatively impact appliances, especially inductive loads like air conditioners and refrigerators.
- OEM Orders: We accept OEM orders, allowing you to customize the inverters with your company logo on the inverters, nameplates, and packaging.
- Expert Recommendations: Our sales team will assist you in choosing the right inverter based on your specific requirements.
- 24/7 Technical Support: We provide round-the-clock after-service consultancy to ensure any technical issues are resolved quickly and easily.
- Optional Power Inverter: While not essential for a solar energy system, our power inverters enable you to have 220 or 230 volts AC, allowing you to use normal AC appliances.
- Input Voltage Options: Our inverters are available in 12, 24, and 48 volt options, allowing you to choose the voltage that suits your needs. Higher voltages result in lower currents, enabling the use of smaller wires between your solar panel array and battery bank.
- Free Spare Parts: In case of any faulty products, simply send us pictures or videos, and we will provide the necessary spare parts for the PCB board free of charge as part of our after-sale service.
