Product Description

The Goodwe GW15K-SDT-30 15kW SDT G3 Three-Phase Inverter is a grid-tied string inverter designed for three-phase installations that require stable power, high performance, and a robust IP66 format. With 2 high-current MPPTs (up to 32 A and 22 A), a maximum efficiency of 98.5%, and 110% AC output capability, it ensures optimal energy production with next-generation panels and precise export control thanks to its integration with a smart meter.

Main Features

Nominal AC power: 15 kW, with overdelivery up to 16.5 kW.
2 independent MPPTs (32/22 A) for strings with different currents and irradiance.
Wide MPPT range: 140–1000 Vdc, maximum input voltage 1100 Vdc.
Max. efficiency 98.5% (European 98.2%) for more useful kWh throughout the year.
IP66 protection rating, -30 to +60 °C, night consumption <1 W.
RS485 and SEMS communications; WiFi/LAN/4G/Bluetooth via accessories.

Advantages or Benefits

Superior production: high efficiency and 110% overcapacity reduce losses during solar peaks.
True flexibility: asymmetric MPPTs that accept high-current modules without limiting production.
Safe outdoor installation: IP66 enclosure and robust electronics for outdoor use.
Export management: integration with Smart Meter for zero export and load optimization.
Silent operation: intelligent ventilation with low noise level and minimal maintenance.
Comprehensive safety: anti-islanding, RCMU, DC isolator, and compatibility with type II SPD on DC/AC.

Purpose or Applications

Ideal for three-phase self-consumption in large residences, communities, and businesses with significant daytime demand. The Goodwe SDT G3 performs especially well on rooftops with long strings and high-current TOPCon or PERC panels, and allows export control to comply with local regulations or maximize self-consumption by diverting surplus to loads such as water heaters or electric vehicle chargers.
