GoodWe MT 80 kW Three-Phase Solar Inverter GW80K-MT

The GoodWe MT GW80K-MT is a three-phase solar inverter with 80 kW of power, designed for commercial and industrial (C&I) applications. Its 4 MPPT architecture with 2 inputs per MPPT allows for string design with different orientations and power levels, maximizing annual energy yield. With IP65 protection, high-efficiency electronics, and professional communications, it ensures reliable operation and simplified O&M.

Main Features

• Nominal AC Power: 80 kW (three-phase 3×400 V, 50/60 Hz).
• PV Architecture: 4 independent MPPTs with 2 strings per MPPT (8 total inputs).
• DC Level: Maximum voltage 1100 Vdc; wide MPPT tracking range for high-current modules.
• Efficiency: up to ~98.7%; high seasonal performance across the entire load range.
• DC/AC Oversizing: Supports DC oversizing and temporary AC overloading (per manufacturer conditions).
• Protection: IP65 rating for outdoor/indoor protected installation; AFCI option depending on version.
• Thermal Management: Intelligent forced ventilation for stability in hot climates.
• Electrical Safety: Anti-islanding, insulation monitoring, RCMU, SPD on DC/AC, and integrated DC switch.
• Connectivity: RS-485 standard (Modbus); connectivity options for portal/app with guided commissioning.
• Monitoring: String-level monitoring and I-V diagnostics for proactive maintenance.

Installation Advantages

• Flexible design with 4 MPPTs reduces losses from shading and mixed orientations.
• High efficiency and stable operation to boost annual energy production.
• Quick commissioning and remote O&M reduce time and travel costs.
• Robust IP65 construction designed for long service life in C&I environments.

Recommended Applications

• Large commercial/industrial rooftops and ground-mounted C&I sites.
• Projects requiring string-level diagnostics and centralized control.
• Installations with high-current modules (182/210 mm format) and long strings.

Installation and Best Practices

• Size strings within the voltage/current limits of each MPPT.
• Complete DC/AC protections and isolation according to regulations and DSO requirements.
• Allow for ventilation and perimeter space for thermal dissipation and maintenance.
• Commission via app/portal, verify communications, and register the device on the platform.

Dimensions and Weight

• Equipment dimensions: n/a (see official GoodWe datasheet).
• Weight: n/a (depends on version; update when published by the manufacturer).

The GW80K-MT balances power, flexibility, and reliability with a suite of diagnostic tools that reduce CAPEX/OPEX and speed up commissioning, making it ideal for C&I projects that demand consistent output and efficient maintenance.
