Sungrow 450W S450S-V11 Rooftop Single-Phase Microinverter
The Sungrow S450S-V11 is a compact 450W single-phase microinverter designed for residential and small commercial rooftop PV systems. With one independent MPPT input and an ultra-wide 16–60V MPPT operating range, it converts power at module level to help reduce the impact of shading, soiling, panel mismatch and different roof orientations.
Plug-and-play AC connections, DC Stäubli MC4 terminals and pre-wired cables help simplify installation. One-click configuration allows connected microinverters to synchronise automatically, while up to 10 units can be installed per AC branch, subject to Sungrow’s installation requirements and the final system design.
When connected to the Sungrow monitoring ecosystem, the S450S-V11 provides real-time module-level monitoring and helps identify connection issues or underperforming panels. Its IP67 enclosure, C5 corrosion resistance and aluminium rear housing support reliable outdoor operation and effective heat dissipation.
