48 V, 100 A Rack-Mount Battery Module GBLR-48-100, 4.8 kWh GETI

Product detailed description

Geti GBLR-48-100 Rack Battery – Powerful, Smart, and Safe Power for Your System

The Geti GBLR-48-100 is a high-performance LiFePO₄ battery in a rack-mount design, engineered for modern energy systems, particularly photovoltaic installations and backup power sources. With a capacity of 100 Ah and an energy storage of 4,800 Wh, it provides a reliable, long-term power source with an outstanding service life exceeding 6,000 cycles at 80% DOD.

The battery is equipped with an integrated battery management system (BMS) that protects the battery against overcharging, deep discharge, short circuits, overheating, and overcurrent, thereby ensuring maximum safety and service life. It also features a clear LCD display for monitoring operating data and real-time power output. Thanks to support for the CAN, RS485, and RS232 communication protocols, the battery is fully compatible with leading inverter brands such as DEYE, GROWATT, GOODWE, SOLAX, SOLIS, VICTRON, and MEGAREVO.

Installation is simple thanks to the standardized dimensions for a 19" rack, which allows for easy and organized integration into equipment cabinets or distribution panels. Up to 15 batteries can be connected in parallel, allowing you to meet even higher power demands.
