The upgraded EG4-LL (Lifetime Lithium) 25.6V (24V) 5.12kWh Lithium Iron Phosphate battery with a 100A internal BMS builds on the proven features of the previous EG4-LL model. It is fully compatible with earlier EG4-LL units, making it a seamless upgrade for existing setups.
This battery consists of (16) UL-listed prismatic 3.2V cells, which have been rigorously tested for 7,000 deep discharge cycles to 80% DoD. You can fully charge and discharge this battery daily for over 15 years, with reliable performance and 99% operating efficiency.
The battery also includes a built-in LCD screen for quick monitoring of key data. In addition, it now supports selectable closed-loop inverter communications, including Schneider, Solark, Victron, Growatt, and EG4, offering an easy plug-and-play interface for effortless setup.
Included:
- (1) 1-foot RS485 Communication Cable and (1) Set of Parallel Cables per battery
- (1) RS485 USB Battery Communication Cable for every 6 batteries (shipped separately)
