Deye Residential ESS
GB-L Pro Home Batteries
A high-voltage, stackable LiFePO4 storage family from 8 kWh to 24 kWh, available as the GB-L8, GB-L12, GB-L16, GB-L20 and GB-L24 Pro.
Store your solar, use it after sunset
The Deye GB-L Pro series is a floor-mounted, high-voltage home battery built around 4 kWh LiFePO4 modules. You stack between two and six modules on a single base, and the cable-free connection between them keeps the installation tidy while improving round-trip efficiency.
Because the whole family shares one module, one control box and one footprint of 540 × 385 mm, you can start with 8 kWh today and grow the stack later as your consumption changes. Under Cyprus net billing, where self-consumed energy is worth considerably more than exported energy, storage is what turns midday production into evening savings.
- • 8, 12, 16, 20 or 24 kWh in a single stack
- • Pairs with high-voltage hybrid inverters via the GB-LBS Pro control box
- • IP65 rated with ≥C2 anti-corrosion protection for Cyprus coastal homes
- • 10-year warranty and a 6000-cycle design life
Why the GB-L Pro series
High-voltage stack design
Cable-free high-voltage stacking delivers higher efficiency and a faster, cleaner installation.
All-round safety
A built-in explosion relief device dredges gas and the fire protection device cuts off the fire source within 3 seconds.
Built for durability
IP65 protection and a ≥C2 anti-corrosion design deliver long-term durability in coastal Cyprus conditions.
Thermal management
Intelligent temperature sensing across core components ensures stable, reliable performance.
Wide temperature operation
Low-temperature battery cells enable reliable performance in environments below -20°C.
Smart, visible management
Real-time alerts, remote upgrades and an intuitive LCD interface keep the system always under control.
Specifications by variant
All five variants share the same 4 kWh module, chemistry and footprint. The differences come down to how many modules are stacked.
