GoodWe SDT G3 Series 50kW Solar Inverter
Overview
The GoodWe SDT G3 Series inverter, with a 50kW capacity, delivers exceptional performance. It is designed for commercial and industrial (C&I) applications, offering suitability for noise-sensitive environments such as schools and hospitals due to its ultra-low noise level of under 50 dB.
Key Features:
- High Power Generation: Features 4 MPPTs, a maximum efficiency of 98.7%, 21A per string, and 180% PV oversizing.
- Cost-Effective Design: Supports aluminum cable for lower Levelized Cost of Energy (LCOE) and includes string-level monitoring for easy Operation & Maintenance (O&M).
- Superb Safety & Reliability: Equipped with AI-driven AFCI 3.0 for safety (optional function), Type II SPD on both AC and DC sides, and IP66 ingress protection.
- Friendly & Thoughtful Design: Operates quietly at under 50dB and features a compact design for easy installation.

Notes:
- *1: When the input voltage is 1000V-1100V, the inverter will enter standby mode. The inverter will return to normal operation state when the voltage returns to the MPPT working voltage range.
- *2: Please refer to the user manual for the MPPT Voltage Range at Nominal Power.
- *3: For Brazil and Colombia is Integrated.
- *4: For Brazil, WiFi+Bluetooth is standard.
