Deye GB-W94 – 94kWh modular high-voltage battery system

The Deye GB-W94 is the flagship of Deye's cabinet-based high-voltage storage systems. With a massive total capacity of 94 kWh it marks the summit of the modular HV series and has been specially designed for industrial applications as well as large-scale energy projects. It provides a complete all-in-one solution for users with the highest demands in terms of capacity, resilience and efficiency.

Thanks to the intelligent interconnection of high-performance battery modules in a sturdy cabinet system, the GB-W94 supplies the required energy for complex load profiles. In combination with Deye hybrid inverters, it forms a highly efficient power plant that maximises self-consumption and reduces dependency on public power grids to a minimum.

Highlights at a glance

• Maximum energy density: With 94 kWh capacity, the system provides one of the largest storage capacities in its class for business and industry.
• Future-proof LiFePO4 cells: Uses lithium iron phosphate technology for maximum thermal stability and a superior service life of over 6000 cycles.
• Highly efficient HV design: The high operating voltage ensures minimal loss during energy transmission and allows the supply of high-performance consumers.
• Integrated master BMS: A state-of-the-art management system continuously monitors all parameters and ensures optimal power distribution and cell maintenance.
• Industrial cabinet system: The robust construction protects the modules from external influences and enables space-saving installation in the technical room.
• Outstanding load capability: Designed to buffer massive load peaks and, in the event of an emergency power supply, to supply even heavy machinery or entire building sections.
• Cloud-based monitoring: Seamless integration into the Deye platform for monitoring performance and predictive maintenance analysis.

Areas of application

The GB-W94 system redefines the boundaries of energy independence:

• Industry & Production
  • Compensation of peak loads (peak shaving) and provision of process energy to reduce grid charges.
• Large agricultural complexes
  • Self-sufficient supply of automated barns, large PV-powered irrigation systems or processing plants.
• Neighbourhood solutions & microgrids
  • Central storage unit for residential settlements or remote hotel complexes in off-grid operation.
• Data centres & logistics centres
  • Securing critical infrastructures through enormous capacity reserves for uninterruptible power supply (UPS).

Installation & safety instructions

• Static requirements
  • The total weight of this system is considerable. The installation location must have a tested, load-bearing foundation (concrete).
• Fire protection & safety
  • Installation should take place in a separate technical room that complies with the applicable standards for large battery storage and provides sufficient ventilation.
• Certified installation
  • Due to the complexity and high voltages, commissioning may only be carried out by qualified personnel trained by Deye.

FAQs about the Deye GB-W94 battery system

Can this system support a whole business in the event of a power outage?

• Yes, depending on the total load.
  • With 94 kWh of capacity and the corresponding hybrid inverters, the system can carry significant loads for long periods of time and ensures a seamless transition to island operation.

How is the longevity of the storage guaranteed?

• Thanks to the active BMS.
  • The system continuously equalises charge differences between the modules and protects the cells from deep discharge, overcharging and extreme temperatures.

Is the system compatible with wind turbines?

• Yes, without a hitch.
  • Via a compatible Deye inverter, energy from various sources (PV, wind, diesel generator) can be centrally fed and stored in the GB-W94 system.

How is delivery of such a system handled?

• Due to the size, by forwarding agent.
  • The system is delivered securely packaged. On site, special lifting equipment is often required to position the cabinet in its final location.
