The GoodWe SMT 50-60kW inverter series is designed for medium and large-scale commercial solar installations. These inverters convert direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used on-site or fed back into the electrical grid.

Here are some key features of the SMT series:

• High Power Generation: With a maximum AC output power of 55kW for the GW50KS-MT and 66kW for the GW60KS-MT, these inverters are suitable for larger commercial solar arrays.
• Multiple MPPT Trackers: The inverters feature either 5 (GW50KS-MT) or 6 (GW60KS-MT) maximum power point tracking (MPPT) inputs. MPPT technology optimizes energy harvest from the solar array, especially in conditions of partial shading, by finding the point of maximum power output for each string of solar panels connected to an MPPT input.
• Wide Input Voltage Range: The inverters have a wide MPPT operating voltage range of 200V to 950V, providing flexibility in system design and accommodating a variety of solar panel configurations.
• High Efficiency: These inverters boast a maximum efficiency of 98.6% and a European efficiency rating of 98.1%, ensuring minimal energy losses during the DC-to-AC conversion process.
• Fuse-Free Design: This design simplifies maintenance and reduces potential points of failure, making the inverters easier and more cost-effective to maintain.
• Robust Safety Features: The inverters incorporate numerous integrated protection features, including PV string current monitoring, insulation resistance detection, residual current monitoring, reverse polarity protection, anti-islanding protection, and comprehensive AC overcurrent, short circuit, and overvoltage protection.
• Smart Control and Monitoring: These inverters offer remote data monitoring capabilities and support multiple communication protocols, including RS485, WiFi, and optional 4G or PLC. They are also compatible with the Modbus-RTU communication protocol (SunSpec compliant) for seamless integration with monitoring systems.

Additional Features:

• Outdoor Installation: The IP65 ingress protection rating signifies that these inverters are designed to withstand dust and water ingress, making them suitable for outdoor installation.
• Compact Design: Despite their high power output, the inverters have a relatively compact size (520mm x 660mm x 220mm), potentially simplifying installation.
