The Deye SUN-100/125K-SG02HP3-EU-GM8/GM10 is a powerful three-phase high-voltage hybrid inverter designed for commercial and industrial solar energy systems. With rated output power of 100 kW or 125 kW, up to 10 independent MPPT trackers and dual high-voltage battery inputs, it provides a flexible solution for PV generation, battery storage, backup power and energy management.
The inverter supports AC coupling for retrofitting existing solar installations, parallel operation of up to ten units and integration with diesel generators. Its maximum charging and discharging current of 200 A enables high-performance battery operation for demanding commercial applications.
Product highlights
High-performance commercial hybrid inverter
Available with 100 kW or 125 kW rated AC power, the inverter is suitable for commercial buildings, industrial facilities, farms, workshops, logistics centres and larger energy-storage installations.
High-voltage battery support
The inverter supports lithium-ion batteries with a voltage range of 160–1000 V. Two separate battery inputs provide a combined maximum charging and discharging current of 200 A, configured as 100 A + 100 A. Communication with compatible batteries is automatically adapted through the battery management system.
8 or 10 independent MPPT trackers
The SUN-100K-SG02HP3-EU-GM8 is equipped with eight MPPT trackers, while the GM10 models provide ten MPPT trackers. Each MPPT supports two PV strings, making the inverter suitable for complex roofs, different module orientations and large-scale PV arrays.
High PV input capacity
The 100 kW versions support up to 200 kW of connected PV power and 160 kW maximum PV input power. The 125 kW version supports up to 250 kW of connected PV power and 200 kW maximum PV input power.
AC coupling for existing PV systems
AC coupling allows the inverter to be integrated into existing solar installations. This makes it possible to add battery storage and hybrid energy management without completely replacing the existing PV system.
On-grid and off-grid operation
The inverter is suitable for both grid-connected and backup applications. In off-grid mode, it can provide peak power of up to 1.5 times the rated output for ten seconds, helping to start loads with high inrush currents.
Parallel operation
Up to ten inverters can be operated in parallel for both on-grid and off-grid systems. Multiple batteries can also be connected in parallel, enabling scalable commercial energy-storage projects.
100% unbalanced output
The inverter supports 100% unbalanced three-phase output. This allows power to be distributed flexibly between the individual phases when the connected loads are not evenly balanced.
Intelligent energy management
Six programmable time periods can be configured for battery charging and discharging. This enables time-of-use optimisation, peak shaving, self-consumption optimisation and controlled charging during low-tariff periods.
Diesel generator integration
Energy from a compatible diesel generator can be used to supply loads and charge the battery. This provides an additional backup option for commercial sites with unstable grid supply or critical loads.
High efficiency
The inverter reaches a maximum efficiency of 98.7%, a European efficiency of 98.1% and an MPPT efficiency above 99%.
Robust design
With IP65 protection, intelligent air cooling and an operating temperature range from –40°C to +60°C, the inverter is suitable for demanding commercial installations. Output derating applies above 45°C.
Typical applications
- Commercial and industrial PV systems
- Factories and production facilities
- Farms and agricultural businesses
- Logistics centres and warehouses
- Hotels and office buildings
- EV charging infrastructure
- Peak-shaving systems
- Backup-power installations
- Existing PV systems requiring battery retrofitting
- Commercial microgrids with diesel-generator integration
