Deye energy storage system GB-L20 PRO, 20 kWh

The Deye GB-L20 PRO storage system is a high-voltage (HV) modular energy storage system designed to work with solar power plants in both larger residential homes and commercial properties. With this solution, you can efficiently store excess solar energy and significantly reduce your dependence on the grid. The system is fully adapted for reliable operation in harsher climate conditions and meets high safety and quality standards.

This GB-L20 PRO storage system belongs to the Deye GB-L-PRO series and consists of five 4 kWh modules, with a total capacity of 20 kWh. This modular design allows the system to be easily adapted to individual needs and, if necessary, expanded up to 24 kWh. High system efficiency, low energy losses, and compatibility with modern hybrid inverters are guaranteed due to its high-voltage architecture and series connection of modules without additional cables.

Deye places great emphasis on safety – the storage system features a reliable and stable LiFePO4 (lithium iron phosphate) battery chemistry. The system is also additionally equipped with explosion pressure relief and fire protection, which suppresses any potential fire source within seconds. This integration guarantees safe operation of the system in all facilities.

The system also features advanced thermal management, which constantly monitors the temperature of critical components – battery cells, connectors, and power parts. A wide operating temperature range allows the system to operate safely from -20 °C to +55 °C. If required, an optional heating function is available for operation during the cold season. The integrated IP65 protection class guarantees resistance to dust and water, allowing the storage system to be installed both outdoors and indoors.

The system features an integrated LCD screen, where you can monitor the battery's state of charge in real time.
