Why choose this product

Why Choose Us

Safety is a key focus of the GB-L solar power off grid battery bank. It features built-in explosion relief to vent gas and fire protection to cut off the ignition source. The high-voltage battery modules connect in series without cables for increased reliability. Thermal sensors monitor cell and system temperatures, and the optional heating system allows operation down to -20°C.

With an IP65 rating and anti-corrosion protection, the GB-L solar power off grid battery bank can withstand challenging environments.

The smart GB-L solar power off grid battery bank enables remote monitoring and upgrades. It provides real-time system data like the state of charge on the LCD display and to connected devices via CAN bus and RS485. With a depth of discharge up to 90%, the GB-L provides excellent energy capacity to power off-grid loads.

Backed by a 10 year warranty, the long-lasting LiFePO4 chemistry offers over 6000 cycles to 70% of original capacity.

With dimensions from 650mm to 1530mm high depending on the number of modules, the floor-mounted GB-L solar power off grid battery bank scales to fit applications from small off-grid cabins to village microgrids. Weighing from 97kg to 253kg, the modular and compact design simplifies transport, installation and maintenance.

The advanced Deye GB-L solar power off grid battery bank intelligently stores and supplies solar energy for resilient off-grid power. Its safe, robust and flexible architecture meets the needs of challenging off-grid renewable energy projects.
