GoodWe SMT Series Solar Inverters
50-80kW | Three Phase | 6 MPPTs
Product Overview
The SMT Series string inverters, available in 50kW to 80kW capacities, are designed to meet the demands of commercial and industrial (C&I) applications by delivering high energy yields and exceptional power density. The 50kW model is specifically engineered for low-voltage (127/220Vac) commercial installations.
Specifically tailored to accommodate high-power PV modules, it boasts multiple MPPTs and a high input current of 21A per DC string, ensuring optimized overall yield. Safety is paramount, with both DC and AC sides featuring Type II surge protection, while AFCI is available as an optional feature.
Key Features
- Smart Control & Monitoring: Remote data monitoring compatible with multiple communication methods.
- High Power Generation for High Returns: Up to 180% DC input oversizing (for GW50K-SMT-L-G10) and 6 MPPTs with a maximum efficiency of 98.6%.
- Superb Safety & Reliability: Type II Surge Protection for both DC and AC sides, IP66 protection for outdoor installation safety, and optional AFCI.
- Flexible & Adaptable Applications: Compatible with 182/210mm modules and offers a wide input operating voltage range.
