Deye SUN-125K-SG02HP3-EU-GM10 - 125 kW / 3-phase hybrid inverter

The Deye SUN-125K-SG02HP3-EU-GM10 is one of the most powerful three-phase high-voltage hybrid inverters on the market. With an impressive AC output power of 125 kW it is specifically designed for industrial mega-projects and large commercial systems. It combines the functions of a highly efficient grid inverter with the flexibility of a massive energy storage system.

Thanks to the GM10 platform this model offers exceptional power density and supports cutting-edge energy management strategies. It is the ideal solution for companies aiming for full control over their energy flows, to minimise peak loads (peak shaving) and to ensure reliable emergency power supply in the megawatt range.

Highlights at a Glance

• Maximum hybrid output: 125 kW nominal power for the most demanding industrial load profiles and large-scale storage concepts.
• 10 MPPT trackers: Offers unparalleled flexibility in string configuration and enables maximum yields even in complex roof structures or partial shading.
• High-voltage battery interface: Optimised for operation with high-performance high-voltage (HV) batteries, increasing system efficiency and reducing installation costs.
• Peak Shaving function: Intelligent capping of peak loads to significantly reduce grid charges for commercial users.
• True emergency power capability: Offers an extremely fast switchover time of under 10 ms to continue critical processes seamlessly even during a grid failure.
• Support for diesel generators: Separate connection for external generators to guarantee system autonomy in emergencies or during prolonged periods of no sunshine.
• Scalable system architecture: Supports parallel connection of multiple units for storage systems ranging from hundreds of kilowatts up to megawatt-scale solutions.

Areas of Application

The SUN-125K-SG02HP3 is designed for the focal points of the modern energy transition:

• Large industry & factory complexes
  • Maximise the self-consumption rate and protect against costly production downtime by integrated backup scenarios.
• Commercial charging parks
  • Buffering of solar power to supply ultra-fast charging stations (HPC) for electric lorries and bus fleets.
• Large-scale Agri-PV & agriculture
  • Energy supply for large automated systems, cold stores, and processing centres.
• Microgrids & neighbourhood storage
  • Establishing independent electricity grids for remote locations or modern, energy self-sufficient housing estates.

Installation & Safety Instructions

• Statics & installation
  • Due to its size and weight, installation on a load-bearing industrial wall or a special floor stand is absolutely necessary. Lifting equipment is required for positioning.
• Battery system selection
  • This model requires a compatible high-voltage storage system (e.g. Deye GB-W series). Ensure correct sizing of the battery voltage level.
• Thermal management
  • The active cooling system is designed for high loads. Ensure the installation site has sufficient ventilation to avoid thermal derating.

FAQs on the Deye 125 kW Hybrid Inverter

Can the inverter work AC-coupled with existing systems?

• Yes.
  • It can accept the surplus from existing string inverters (including third-party brands) and charge it into the connected high voltage battery.

Is the device suitable for black start?

• Yes.
  • The system can restart after a complete grid failure solely using the energy from the PV modules and battery (Black Start) to reactivate the supply.

How many MPPT strings can be connected?

• Two per MPPT.
  • With 10 MPPT trackers, up to 20 strings can be connected in total, allowing extremely precise control of the PV system.

What monitoring options are available?

• Full cloud connectivity.
  • Via the Deye Cloud and the Solarman app, all parameters (battery status, PV yield, household consumption) can be monitored in real time and settings adjusted remotely.
