SUNGROW | Inverter Hybrid SH15T-V11_S 15kW 3MPPT + DTSU666-20 Smart Meter with 3x100A CT clamps

The SUNGROW SH15T-V11_S is a three-phase hybrid inverter designed for larger residential and small commercial solar-plus-storage systems, delivering 15 kW AC output with 3 independent MPPT inputs for flexible PV design. It supports high-voltage battery storage (such as the SUNGROW SBR series) and provides seamless integration of PV, battery, and grid power to maximize self-consumption, ensure backup functionality, and meet grid export requirements.

Bundled with the SUNGROW DTSU666-20 Smart Meter, including 3×100A current transformers (CTs), this solution enables real-time energy monitoring, precise export limitation, and comprehensive system control through the iSolarCloud platform. It’s ideal for energy-conscious users who demand high efficiency, smart features, and robust backup capabilities.
