Description

Product Description

The Sungrow 8 kW single-phase hybrid inverter (model SH8.0RS) is engineered for modern residential and light commercial solar energy systems that require seamless solar generation, battery storage integration, and backup power capability. This inverter supports large PV arrays with 200 % DC/AC oversizing and features multiple Maximum Power Point Trackers (MPPTs) to maximise energy harvest from differently oriented solar arrays. It integrates a built-in Energy Management System (EMS) that balances PV generation, battery charging/discharging, and export to maximise self-consumption and minimise grid reliance. The inverter also includes backup functionality with rapid switchover to battery power during grid outages for critical loads.

Real-time performance data is available via Sungrow’s iSolarCloud platform with refresh rates as frequently as every 10 seconds. Intelligent functions like PID recovery and online diagnostics improve system uptime and performance. Designed for flexibility, the unit supports retrofit and new installations, and it is compatible with Sungrow battery stacks ranging from around 9.6 kWh up to ~19.2 kWh or more depending on configuration. The rugged IP65/66 enclosure and fanless cooling ensure reliable operation in a wide set of operating conditions while maintaining quiet performance.
