The DEYE SUN-80K-G03 converts the energy generated by photovoltaic panels into three-phase electrical energy compatible with 380/400V utility grids. Its rated output power of 80kW makes it suitable for large commercial and industrial installations.
The maximum supported photovoltaic power is 104kW. Its four MPPT trackers, each with four string inputs, provide flexible PV array connection and management, including installations where groups of panels have different orientations or irradiation conditions.
The MPPT operating range is 200–850V, while the maximum input voltage is 1000V. The maximum operating current is 40A per MPPT, while the maximum short-circuit current is 60A per MPPT.
The inverter offers a maximum efficiency of 98.7%, an IP65-rated enclosure and intelligent air cooling. RS485 and RS232 interfaces enable monitoring-system integration, while GPRS, Wi-Fi, Bluetooth, 4G or LAN connectivity is available through optional modules.

Benefits
High Output for Commercial Applications
The 80kW rated output allows the inverter to be used in photovoltaic systems installed on industrial buildings, warehouses, manufacturing facilities and commercial buildings.
Flexible PV Array Management
The four MPPT trackers allow the panels to be divided into independently managed groups, helping optimise production when panel orientations or operating conditions differ.
Flexible DC-to-AC Ratio
The maximum photovoltaic power of 104kW allows the PV array to be larger than the inverter’s rated AC output, subject to the manufacturer’s limits and requirements.
Integrated Protection Functions
The inverter includes protection against DC reverse polarity, overcurrent, overvoltage, short circuits, excessive temperature, insulation faults, residual current and unintended island operation.
Remote Monitoring
The connectivity options enable production and operating parameters to be monitored through compatible platforms.
Recommended Applications
- Industrial buildings and premises
- Factories and manufacturing facilities
- Warehouses and logistics centres
- Commercial buildings
- Business centres
- Farms and agricultural facilities
- Commercial photovoltaic power plants

Compatibility and Important Information
This is an on-grid inverter. It does not have a battery input and does not provide backup power when the utility grid is unavailable.
The Zero Export function requires a compatible meter or metering system that has been correctly installed and configured.
Smart string monitoring, Anti-PID, AFCI protection and wireless communication modules are optional. Their inclusion must be checked in the supplied commercial configuration.
The maximum photovoltaic power of 104kW must not be confused with the rated AC output power of 80kW.
The PV strings must be sized according to the panels’ Voc, Vmp, Isc and Imp values, the limits of each MPPT tracker and the minimum and maximum temperatures at the installation site.
Compatibility with the distribution system operator’s requirements and the regulations applicable to the project must be checked before purchase.
Installation, configuration and commissioning must be carried out by qualified personnel in accordance with the manufacturer’s instructions and all applicable regulations.
