ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW
The STS series is a new solar storage inverter developed by Guangdong Solarthon Technology Co., Ltd. It is designed to integrate solar energy storage, mains charging energy storage, and AC sine wave output. With its DSP control and advanced control algorithm, the STS series offers high response speed, reliability, and industrial standard.
The inverter features four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power. This flexibility allows for different 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 maximum energy conversion from the solar panel in real-time, with a wide voltage range of MPPT.
The AC-DC charge module employs 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 wide AC voltage input range and full input/output protection function ensure stable and reliable battery charging.
The DC-AC inverter module is based on a full digital intelligent design and utilizes advanced SPWM technology to output pure sine wave power. It efficiently converts DC power into AC power, making it suitable for a wide range of 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. The comprehensive electronic protection function ensures the safety and stability of the entire system.
