Sungrow SH15T

Three-phase Hybrid Inverter for PV + Storage: Sungrow SH15T

The Sungrow SH15T is a three‑phase hybrid inverter engineered for homes and small businesses that require reliable backup power, flexible solar integration, and robust outdoor performance. It combines a strong 30 kW PV input capacity with an integrated 63 A bypass for seamless whole‑home backup and an automatic 10 ms transfer to keep critical loads powered during outages. Its IP65 protection with C5 rating ensures outdoor suitability, while its ability to support 100% unbalanced outputs makes it adaptable to complex roof layouts and varying shading conditions.

Applications and use cases

This versatile inverter is suited for residential rooftops and light commercial installations where reliable backup and efficient energy management are essential. It supports outdoor installations thanks to its rugged enclosure, and its three‑phase design is ideal for larger homes or small businesses with uneven load profiles. The SH15T’s flexible PV input and unbalanced output capabilities enable installation across diverse PV configurations and site layouts, delivering steady performance even when sun exposure is non‑uniform.
