Product Description

The Goodwe GW20K-SDT-30 20kW SDT G3 Three-Phase Inverter is designed for light C&I self-consumption projects and large residences that require high power, robustness, and total control of energy flow. Its 2 high-current MPPTs (32/22 A), maximum efficiency of 98.5%, and IP66 protection rating ensure stable production with next-generation panels, even in demanding environments. In addition, the ability to deliver up to 110% in AC allows you to take advantage of irradiance peaks and maximize annual performance.

Main Features

Nominal AC power: 20 kW, with overdelivery up to 22 kW.
2 asymmetric MPPTs (32/22 A) for designing strings with different currents.
Wide operating range: MPPT 140–1000 Vdc; max. input voltage 1100 Vdc.
Max. efficiency 98.5% (European 98.2%) for more usable energy.
IP66 protection, -30 to +60 °C, night consumption <1 W; intelligent ventilation.
SEMS and RS485 integration; optional WiFi/LAN/4G/Bluetooth for commissioning and monitoring.

Advantages or Benefits

Higher annual production: high efficiency and 110% overcapacity reduce losses during peak hours.
Compatibility with high-current modules: avoids limitations and ensures MPPT at its optimal point.
Reliable outdoor installation: IP66 enclosure and electronics prepared for outdoor conditions.
Export control: integration with smart meter for zero export and load management.
Silent and safe operation: anti-islanding, RCMU, and integrated DC switch; compatible with type II SPD.
Minimal maintenance: 24/7 monitoring on the SEMS platform and remote diagnostics.

Purpose or Applications

Aimed at commercial buildings, warehouses, offices, and three-phase residences with significant consumption, the Goodwe SDT G3 offers a solid foundation for projects seeking short payback periods and operational control. It is ideal for rooftops with long strings of TOPCon/PERC panels and, together with a smart meter, allows prioritization of internal consumption (HVAC, DHW, EVSE) and compliance with zero export requirements.
