Product Features of LiFePO4 Battery Pack

This lifePo4 battery pack is built from 3.2V 314Ah cells in a 16S1P configuration, and its modules stack, connect wirelessly, and expand with the site. Paired with a hybrid inverter, it serves as a dependable lifePO4 solar battery for self-consumption and backup.

Flexible Expansion: up to 4 clusters in parallel, from 32.14kWh to 257.12kWh of capacity.
Easy Installation: stackable design with wireless connection between modules.
Auto-Configuration Modules: Stackable auto-configuration modules keep setup simple.
IP54 Protection: suitable for both indoor and outdoor installations.
Long Cycle Life: 8000 cycles at 70% SOH, 90% DOD (25°C).
High Current Capability: 150A allowed max discharge current (160A for 3 s peak) and 157A allowed max charge current (170A for 2 s peak).
Inverter Communication: CAN interface for inverter and PC control and monitoring.

Commercial Applications of LiFePO4 Battery Pack

The LFP-M-S lifepo4 battery pack is part of the Hybrid High Voltage System lineup, shown alongside the HES 22-50kW HT and HES 125kW HT hybrid inverters. In a hybrid system, solar power supplies the load first, surplus energy charges the battery, and any further surplus is fed back to the grid. When solar generation is insufficient, the battery and grid supplement the supply.

Applications & Use Cases

Solar self-consumption: store excess PV energy and discharge it when generation drops.
Peak shaving and demand management: reduce demand peaks with stored energy.
Grid congestion relief: eases congestion in areas with high solar penetration.
Virtual power plants (VPPs): support participation in electricity market services.
Seamless backup power: keeps critical loads running where high supply continuity is required.
Scalable commercial storage: up to 4 parallel clusters turn the lifePO4 solar battery bank into 257.12kWh of capacity.
