Description
Product information
The Deye GB-L-PRO4.1 is a state-of-the-art expansion module for the GB-L high-voltage battery series from Deye. With a gross capacity of 4.09 kWh It serves as a building block for scalable energy storage systems in domestic and small commercial settings. By combining several modules, the capacity can be precisely tailored to individual energy requirements.
Based on the safe Lithium iron phosphate technology (LiFePO4) the module offers exceptional cycle stability and thermal stability. The innovative stacking design enables a wireless connection between the modules, which minimises installation effort and ensures a clean, compact appearance.
Key features at a glance
- Scalable energy: One module offers a capacity of 4.09 kWh – by simply stacking several units, a bespoke high-voltage system can be built.
- Safe LiFePO4 technology: The cobalt-free cell chemistry guarantees maximum safety and a long service life, and virtually eliminates the risk of thermal runaway.
- Plug-and-play installation: Thanks to integrated plug-in contacts, there is no need for complex DC cabling between the individual battery modules during stacking.
- High efficiency: As part of a high-voltage system, the module operates with minimal conversion losses, which increases the efficiency of the entire PV system.
- Robust & Durable: Designed for over 6,000 charge cycles, the module offers a future-proof investment in your energy independence.
- Protection class IP65: The housing reliably protects the sensitive electronics from dust and water jets, making it ideal for a variety of installation locations.
Areas of application
The GB-L-PRO4.1 module is the flexible basis for a wide range of storage solutions:
- System extension
- Easily expand your existing Deye GB-L battery storage system by an additional 4.09 kWh if your energy requirements increase (e.g. due to an electric car or a heat pump).
- New installations in residential areas
- Combine 2 to 6 modules to form a powerful high-voltage tower for maximum self-consumption of electricity.
- Commercial storage solutions
- Creation of larger storage capacities by connecting several battery towers in parallel to manage peak loads.
Installation & safety instructions
- Required components
- Please note that at least one battery management system (GBL-PRO BMS) and a base plate (Base). The module alone is not operational.
- Stacking limits
- Please note the maximum number of modules per tower as specified in your Deye system (usually up to 6 modules per BMS).
- Condition of the modules
- In the event of a subsequent expansion, the existing modules and the new module should be brought to a similar state of charge (SOC) to enable the BMS to achieve an optimal balance.
FAQs on the Deye GB-L-PRO4.1 battery module
Can I connect a single 4.09 kWh module directly to the inverter?
No.
- As this is a high-voltage system, a minimum number of modules (usually 2 or 3, depending on the inverter specifications) and the corresponding battery management system (BMS) are absolutely essential to achieve the required operating voltage.
How long is the warranty on the Deye battery modules?
Usually 10 years.
- Deye The manufacturer usually provides a performance guarantee of 10 years or a specified number of cycles for its LiFePO4 storage modules, provided that the installation has been carried out by qualified personnel.
Can I set up the module outdoors?
Yes, subject to certain conditions.
- Thanks to its IP65 rating, the module is weatherproof. Nevertheless, the installation site should be protected from direct sunlight and extreme frost in order to preserve the cell chemistry and optimise the efficiency of the optional heating function.
Do I need to buy extra cables if I expand the system?
No.
- Power and communication connections are established directly via the integrated connectors when the modules are stacked on top of one another. Only the connection from the BMS to the inverter requires a suitable cable set. However, this is included with the PDU and the base. Please contact the sales department if you have any questions.
How heavy is a battery tower with 4 modules?
Quite substantial.
- A single module weighs approx. 39 kg. A tower comprising 4 modules, including the BMS and base, weighs over 170 kg. It is therefore essential that you check the load-bearing capacity of your floor.
