48V 100A rack-mounted battery module GBLR-48-100 4.8 kWh GETI

Geti GBLR-48-100 rack-mounted battery – powerful, smart and safe power for your system

The Geti GBLR-48-100 is a high-performance LiFePO4 rack-mounted battery designed for modern energy systems, particularly for photovoltaic installations and backup power supplies. With a capacity of 100 Ah and energy of 4800 Wh, it provides a reliable, long-term power source with an excellent service life of over 6000 cycles at 80% DOD.

The battery is equipped with an integrated BMS (Battery Management System), which protects it 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 straightforward thanks to its standardised dimensions for a 19" rack, allowing for easy and neat integration into technical cabinets or switchboards. Up to 15 batteries can be connected in parallel, enabling you to meet even higher energy demands.
