Product Description

ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW

The STS series is a cutting-edge solar storage inverter that combines solar energy storage, mains charging energy storage, and AC sine wave output. With its advanced DSP control and control algorithm, this inverter offers exceptional response speed, reliability, and industrial standard. It offers four charge modes: solar power only, mains power priority, solar power priority, and mains power & solar power. Additionally, it allows for selectable inverter and mains outputs to cater to 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 extraction from the solar panel, thanks to its 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. This results in precise control accuracy and a compact design. The module offers stable and reliable charging and protection for the battery, with 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 a 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 system operation data and status. With its comprehensive electronic protection function, the system ensures safety and stability.
