The provided excerpts from the "GW_HT 73-120K_Datasheet-EN.pdf" document describe the GoodWe HT 1100Vdc series of string inverters, designed for commercial and industrial (C&I) and small utility solar energy projects. These inverters, ranging from 73kW to 120kW, are engineered for optimal energy generation and return on investment in medium to large-scale solar power systems.

• High DC Input Voltage: The HT series can handle a maximum input voltage of 1100Vdc, which is suitable for systems with longer strings of solar panels, reducing installation costs and complexity.
• Multiple MPPT Trackers: The inverters feature up to 12 Maximum Power Point Tracking (MPPT) inputs, allowing them to independently optimize power output from multiple groups of solar panels with different orientations or shading conditions. This maximizes energy harvest, especially in installations with complex roof layouts or partial shading.
• High Power Density: The HT series boasts a compact design for its power output, minimizing the physical footprint and making it suitable for installations where space is limited.
• Flexible Output Configuration: The inverters offer a range of output voltage options (220V, 380V, 400V), accommodating various grid requirements in different regions.
• Wide Operating Temperature Range: With an operating temperature range of -30°C to +60°C, these inverters can withstand harsh environmental conditions, ensuring consistent performance in diverse climates.
• Advanced Monitoring and Control: The inverters offer both local monitoring via LED/LCD displays and remote monitoring capabilities through RS485, WiFi, or optional 4G connectivity. This allows users to track system performance, energy production, and receive alerts remotely.
• Comprehensive Protection Features: The HT series incorporates a multitude of protection features to ensure safety and reliability. These include safeguards against overcurrent, short circuits, overvoltage, reverse polarity, ground faults, and islanding conditions. This comprehensive protection scheme protects the inverter, solar panels, and the electrical grid from various faults and abnormal operating conditions.
• Easy Installation and Configuration: Features like Bluetooth connectivity and power line communication simplify the installation and configuration process.

These inverters are specifically designed for:

• Commercial and Industrial Solar Systems: Their high power ratings, multiple MPPT trackers, and robust design make them well-suited for larger commercial rooftops and ground-mounted solar power plants.
• Small Utility-Scale Projects: The HT series can also be deployed in smaller utility-scale solar farms due to their high efficiency, advanced monitoring capabilities, and grid-friendly features.
