The DEYE GB-W 12kWh High-Voltage Lithium Battery is a modular battery energy storage solution designed for commercial and industrial solar power systems, backup power, and energy storage applications in Nigeria. With a 12kWh modular battery capacity, the system can be scaled from 60kWh to 192kWh per battery cluster, making it suitable for a wide range of small and medium commercial and industrial installations.
The GB-W features a cable-free modular stacking design, allowing fast and straightforward installation while reducing system wiring and installation costs. Its quick-release service panel provides easy access for maintenance, while replaceable components can be serviced at cluster level without removing the entire battery system.
Designed for high-performance energy storage, the DEYE GB-W supports a maximum continuous discharge current of 230A and is compatible with DEYE high-voltage hybrid inverters from 30kW to 125kW, as well as DEYE 100kW and 125kW PCS systems. This makes it an excellent battery option for large solar installations, offices, factories, hotels, commercial buildings, estates and other C&I applications requiring reliable battery backup and energy management.
Safety is a major feature of the GB-W battery system. It incorporates cell-level thermal isolation, pack-level aerosol fire suppression, and dual temperature monitoring for both battery cells and electrical connections. The natural air-cooling system uses directional air ducts and dust filtration to improve thermal management and maintain a cell temperature difference of less than 4°C, helping to support battery performance, reliability and service life.
The integrated Battery Management System (BMS) and Energy Management System (EMS) provide intelligent monitoring and coordinated control from the individual battery cells through to the complete energy storage system. Pack-level and cell-level balancing help maintain battery performance, while the modular architecture allows battery packs to be replaced or added during system expansion.
For operation and maintenance, the DEYE GB-W supports local Bluetooth access and remote cloud monitoring, enabling real-time system monitoring, fault diagnosis and remote firmware upgrades. This provides installers and system owners with greater visibility of battery performance and simplifies long-term O&M.
The DEYE GB-W 12kWh battery is well suited for Nigerian businesses and facilities looking to reduce dependence on the grid and diesel generators. It can be deployed in commercial buildings, factories, hotels, offices, hospitals, schools, estates, telecommunications facilities and other high-energy-demand locations.
Its modular high-voltage architecture makes it particularly suitable for large solar hybrid systems and commercial & industrial (C&I) energy storage projects, where reliable battery backup, scalability, remote monitoring and simplified maintenance are important.
