GoodWe LVSMT Series
12-35kW | Three-Phase | Up to 6 MPPTs
The GoodWe LVSMT series is specifically designed for the South American market, targeting low-voltage (127/220Vca) grids commonly used in various Brazilian cities. The LVSMT inverters are available in power ratings from 12 to 35kW, making them suitable for small commercial systems. A significant advantage is the simplified installation, eliminating the need for expensive transformers that can negatively impact system conversion efficiency.
Key Features:
- Intelligent Control and Monitoring: String-level monitoring, eliminating the need for power transformers.
- Excellent Safety and Reliability: Optional AFCI, IP65 Protection Class.
- High Energy Generation for High Returns: Maximum efficiency up to 98.8%, photovoltaic system up to 8% more efficient without a transformer.
- User-Friendly and Practical Design: Wide MPPT voltage range from 200V to 650V, fuse-less design.
