Deye GB-W-11.7 - 11.7kWh battery module for modular high-voltage storage solutions

The Deye GB-W-11.7 is a powerful high-voltage (HV) battery module that serves as a central component for scalable energy storage systems. With a gross capacity of 11.7 kWh per unit, it is specially optimised for use with Deye high-voltage hybrid inverters (such as the SG01HP3 series).

Thanks to its modular design, the GB-W system allows flexible adaptation of storage capacity to individual energy requirements. The modules are connected in series to increase the system voltage, which increases the overall system efficiency and minimises conversion losses compared to low-voltage systems.

Highlights at a glance

• High storage capacity: Provides 11.7 kWh of energy per module for long-lasting power supply in the home or business.
• Lithium iron phosphate technology (LiFePO4): Maximum safety and durability thanks to thermally stable cell chemistry with high cycle resistance.
• Modular scalability: Easy expansion of the system by adding more modules to cover even larger energy requirements.
• High-voltage efficiency: Operates in a high voltage range, which harmonises perfectly with modern three-phase hybrid inverters.
• Integrated battery management system (BMS): Continuously monitors cell voltages and temperatures for safe and optimised operation.
• Easy installation: Thought-out plug-and-mount system for quick commissioning and neat cabling.
• High depth of discharge (DoD): Enables the efficient use of stored energy up to a depth of approx. 90%.

Areas of application

The GB-W-11.7 module is the ideal choice for demanding storage scenarios:

• Single-family houses with a high degree of self-sufficiency
  • Storage of surplus solar power for use in the evening and at night.
• Commercial energy storage
  • Building up larger storage capacities for peak shaving or for optimising self-consumption.
• Emergency power & backup systems
  • Provision of a reliable energy reserve for critical consumers in the event of grid failures in combination with Deye hybrid systems.

Installation & safety instructions

• System control unit required
  • A suitable BMS control unit (controller) is mandatory for operation of the modules, which carries out communication with the inverter.
• Professional installation
  • The battery should be installed on a level, load-bearing surface in a cool, dry place.
• Observe protection class
  • Although the system is robustly built, it should be protected from direct sunlight and extreme humidity to maximise the service life of the electronics.

FAQs on the Deye GB-W-11.7 battery module

What is the maximum number of modules that can be combined?

Depending on system configuration.

• Several modules can usually be stacked in a tower or connected in parallel. The exact maximum number depends on the capacity of the BMS control unit and the specifications of the inverter used.

Is the battery compatible with inverters from other brands?

Primarily optimised for Deye.

• The best performance and simplest setup is achieved in combination with Deye hybrid inverters. For use with third-party systems, the compatibility of the communication protocol (BMS) must be checked in advance.

Do I need special tools for expansion?

Normally no.

• The modules are designed for easy coupling. However, manufacturer-specific connection cables and terminating resistors should be used, which are often included with the controller or modules.

What warranty does Deye offer for the modules?

Usually 10 years.

• Deye usually grants a performance warranty of 10 years or a certain number of cycles (whichever comes first) on its LiFePO4 storage systems.
