Based on the information provided in the "GW_MT_Datasheet-EN.pdf" document and our conversation history, the GoodWe MT Series inverters are a line of three-phase solar inverters designed for medium to large-scale commercial rooftop and ground-mounted solar PV systems.

Here is a summary of the key features and specifications of these inverters:

• Power Output: These inverters have a nominal AC output power ranging from 50 kW to 80 kW, with the capability to handle up to 150% DC input oversizing and deliver up to 115% AC output overloading.
• Efficiency: The MT Series boasts high maximum efficiency levels, ranging from 98.7% to 99.0%, and European Efficiency ratings from 98.3% to 98.5%.
• Input Voltage: These inverters are designed for a maximum input voltage of 1100 V, with an MPPT operating voltage range of 200 V to 1000 V. The start-up voltage is a relatively low 200 V.
• Output Voltage: They offer flexible output voltage options, including 400 V, 500 V, and 540 V, depending on the model.
• Power Quality: The inverters maintain a low total harmonic distortion (THD) of less than 3%, ensuring high power quality and grid compatibility. They also feature a power factor adjustable from 0.8 lagging to 0.8 leading, allowing for reactive power management.
• Protection: The MT Series incorporates several protection features, including PV string current monitoring, insulation resistance detection, residual current monitoring, reverse polarity protection, anti-islanding protection, and overcurrent, short circuit, and overvoltage protection.
• Communication and Monitoring: These inverters offer communication options such as RS485, WiFi, and optional PLC, enabling remote monitoring and control.
• Physical Characteristics: The MT Series inverters have a compact design with dimensions of 586 mm × 788 mm × 264 mm or 586 mm × 788 mm × 267 mm. Their weight ranges from 60.0 kg to 70.0 kg.
• Operating Environment: These inverters are designed to operate in a wide temperature range of -30°C to +60°C.
