This gives the high-voltage battery system a nominal storage capacity of 34.56 kWh and a nominal system voltage of 345.6 V. The operating voltage range of 270 to 394.2 V enables integration into high-performance high-voltage energy storage systems.With a continuous charging and discharging current of 75 A each, the battery storage system is suitable for applications with high energy and power requirements. The recommended depth of discharge is 90 % and can be set to up to 100 % depending on the system configuration.Modular and space-saving system designThe individual Deye GB-L-Pack5.76-A7 battery modules are stacked on top of one another to save space. The wireless stacking configuration between the modules simplifies installation and reduces the amount of cabling required. A high-voltage control and distribution unit, together with a sturdy stand, complete the freestanding battery system.Thanks to its modular architecture, the Deye GB-L-Plus series can be adapted to different storage requirements. For particularly large projects, up to 16 battery clusters can be operated in parallel, provided that the inverter used and the overall system design support this.Safe and durable LiFePO4 technologyThe Deye GB-L34 Plus uses long-life lithium iron phosphate cells. LiFePO4 technology is characterised by high thermal stability, a long service life and reliable performance in stationary storage applications. According to the manufacturer, the battery system achieves at least 6,000 charge cycles under defined test conditions.To ensure a high level of operational safety, the high-voltage storage system features various protective mechanisms at the battery pack, cell and connection levels. These include over-temperature monitoring, an aerosol-based fire protection system and an integrated pressure relief mechanism. The IP66 protection rating protects the housing against dust and powerful water jets.Smart battery and energy managementThe integrated BMS and EMS management monitors and optimises the operation of the battery system in real time. Dual online balancing at cell and battery pack level ensures an even load distribution across the storage modules and contributes to the long service life of the entire system.CAN 2.0, RS485 and Bluetooth are available for communication. Operating data can be monitored locally via Bluetooth and, within a compatible Deye energy storage system, via the Deye cloud. The integrated LCD display also allows direct monitoring of key system information.For domestic and commercial PV systemsWith its storage capacity, the Deye GB-L34 Plus is particularly suitable for larger detached houses, blocks of flats, agricultural holdings and small commercial premises. Surplus solar energy can be temporarily stored and used when electricity demand is high, in the evening hours or to reduce peak loads.When combined with a compatible Deye high-voltage hybrid inverter, this creates a high-performance storage solution for increased self-consumption, better utilisation of your own photovoltaic system and reduced dependence on the public electricity grid.System components6 x Deye GB-L-Pack5.76-A7 battery modules, each with a capacity of 5.76 kWh1 x Deye GB-L-PDU-A high-voltage control and distribution unit1 x Deye GB-L-Base-A stand for the battery system
