GoodWe 20kW Three-Phase On-Grid Inverter (GW20K-SDT-30)

Product Overview

The GoodWe 20kW SDT G3 is the high-capacity flagship of the SDT series, designed specifically for large-scale residential energy independence and commercial rooftop solar projects. Available through Powernest Limited, this unit represents the ultimate balance between raw power and advanced smart-grid technology. With its triple-string input capability and enhanced current handling, it is perfectly suited for modern facilities with high self-consumption needs—such as those running central HVAC systems, electric vehicle (EV) charging fleets, or light industrial machinery.

Key Features

• Maximum Current for Modern Panels: Engineered with a massive 32A / 22A input current across its two MPPTs. This allows for the parallel connection of high-power 550W+ bifacial modules without any risk of current clipping.

• 110% AC Peak Output: The GW20K-SDT-30 is capable of pushing up to 22kVA of apparent power, ensuring that during high-yield summer months, every drop of solar energy is converted for use rather than being curtailed.

• Multi-String Flexibility: Features 3 string inputs (2 strings on MPPT1 and 1 on MPPT2), providing the installation flexibility needed for complex commercial roofs with uneven panel counts or different shading profiles.

• Industrial IP66 Ingress Protection: Built to withstand the most demanding environments, the IP66-rated housing is fully dust-tight and resistant to heavy rain and high-pressure water jets.

• Whisper-Quiet Smart Cooling: Despite its high power output, it maintains a low noise profile (under 45dB) using an intelligent cooling system that only activates when necessary, prolonging the life of the internal electronics.

• Advanced Monitoring & Safety: Includes 24/7 load consumption monitoring and optional AI-based Arc-Fault Circuit Interrupter (AFCI 3.0) and Type II Surge Protection (SPD) on both AC and DC sides.
