GETI GBLW-51-100V2 51.2V 100Ah LiFePO4 wall-mounted battery

Geti GBLW-51-100V2 wall-mounted battery – powerful, smart and safe energy for your system

The Geti GBLW-51-100V2 is a high-performance wall-mounted LiFePO4 battery designed for modern energy systems, particularly for photovoltaic installations. With a capacity of 100 Ah and an energy storage of 5120 Wh, it provides a reliable and long-lasting 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 the battery against overcharging, deep discharge, short circuits, overheating and overcurrent, thereby ensuring maximum safety and service life.

It also features a clear display for monitoring operational data in real time. Thanks to support for the CAN and RS485 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 compact dimensions and wall-mounted design, which saves space and allows for easy integration into plant rooms or switchboard cabinets. Up to 15 batteries can be connected in parallel, enabling you to meet even higher energy demands.
