Product Description

The Goodwe GW17KT-DT 17kW 2 MPPT Three-Phase Inverter belongs to the SDT G2 series and is designed for 400 V three-phase installations that require high reliability and control. With two MPPT trackers and up to two strings per tracker, it achieves an efficiency of 98.4% and allows oversizing of the PV array to maximize annual energy yield.

Main Features

• Nominal AC power: 17 kW (max. output 19 kW; AC overload 110%).
• 2 MPPT (2 strings per MPPT); MPPT range 200–950 V; max. PV voltage 1100 V; startup 180 V.
• Current per MPPT: 25 A (max. I_sc per MPPT 31.2 A); suitable for half-cut/bifacial modules.
• Max. efficiency 98.4% (ηEU 97.7%); THDi < 3% and adjustable power factor.
• IP65, DC isolator, SPD Type III and optional AFCI; active ventilation.
• Wi-Fi/RS-485 connectivity (SEMS portal) and Modbus-RTU (SunSpec).

Advantages or Benefits

• Design flexibility with two MPPT for different orientations.
• Higher annual production thanks to DC oversizing up to 150%.
• Quick installation with plug-and-play connectors and advanced monitoring.
• Outdoor reliability: IP65 enclosure and integrated protections.

Purpose or Applications

Three-phase self-consumption in large homes and SMEs: shops, workshops, and buildings with medium-high consumption connected to 400 V (3L/N/PE).
