Why This Is The Energy Storage Solution You Have Been Looking For
Backed by Deye’s proven engineering expertise, every core feature of the GB-L Plus Series is designed to deliver tangible, measurable benefits that translate directly to lower total cost of ownership and greater long-term reliability for end users:
No Complex Commissioning, Zero Headache O&M
Powered by the exclusive Pack + Cell Dual-Level Online Self-Balancing Technology – a patented innovation from Deye, the system eliminates mandatory pre-configuration procedures completely when you expand capacity or replace individual battery packs. Users no longer need to schedule technical engineers for on-site calibration work, slashing post-installation operation and maintenance costs by over 60%. The deeply integrated Deye BMS + EMS control architecture runs 24/7 real-time full-lifecycle performance optimization, paired with native Bluetooth connectivity and Deye Cloud interconnection capabilities, allowing users to access automatic fault diagnostics, remote system monitoring and one-tap firmware updates with ease.
Space-Saving Modular Design, Scale Up As Your Needs Grow
Featuring a patented cable-free stacking architecture, the GB-L Series achieves industry-leading volume energy density, maximizing vertical space utilization and cutting the required installation footprint by over 30% compared to traditional wired high-voltage energy storage systems. Each single cluster supports a native nominal energy range of 17.28kWh to 80.64kWh, and up to 16 individual modules can be connected in parallel for further expansion. This fully flexible scalability perfectly adapts to diversified demand scenarios, from small ordinary households, sprawling large villas, all the way to small commercial shops, workshops and light industrial facilities, without forced hardware reconfiguration or system replacement as your energy needs increase over time.
Fully Verified Technical Parameters, No Overpromising, All Deliverable Performance
All units in the GB-L Plus Series adopt automotive-grade LiFePO4 cells, with the 5.76kWh base 57.6V 100Ah module certified for over 6000 full charge-discharge cycles under standard test conditions of 25°C±2°C, 0.5C rate, 90% DOD, 70% end-of-life capacity retention, delivering a reliable 10+ years of daily usage, covered by Deye’s official 10-year product warranty (terms and conditions apply). Users can freely adjust the depth of discharge up to 100% without causing irreversible damage to the battery. The full product lineup meets all strict European certification requirements, including IEC 62619, IEC 62040, VDE 2510-50, CEC and UN38.3, for complete peace of mind.

Two Flexible Monitoring Modes, Control Your Energy At Your Fingertips
The GB-L Series seamlessly connects to the Deye App, providing two mutually compatible monitoring modes to suit all on-site and remote usage requirements:
Local Bluetooth Monitoring Mode: No internet connection is required. Users can complete low-power Bluetooth LE one-tap pairing to the battery system, conduct on-site status control and automated firmware upgrade directly via mobile devices, no technical background needed.
Cloud Remote Monitoring Mode: When interconnected with Deye inverters, the full ESS system supports 24/7 real-time equipment tracking, user-customizable intelligent charging/discharging strategies, AI-powered energy consumption data analytics and proactive customized maintenance notifications, helping users continuously optimize their energy usage to save more on electricity costs over the system’s full 10+ year service life.
