B-LFP48-170E
- 51.2V 170Ah 8.8kWh | LFP
At 8.9 kWh nominal (8.0 kWh usable at 90% DoD), the B-LFP48-170E fills the gap between entry-level 5 kWh modules and full-size 10 kWh units. It delivers enough stored energy to meaningfully offset evening and overnight grid consumption in a typical solar self-consumption setup, without the higher upfront cost of a 10 kWh module.

For larger systems, its 63-unit parallel capability scales to 534 kWh without external gateway hardware, making it equally suited to small commercial deployments. The 1C continuous discharge rate (174A rated) delivers the full 8.9 kW output needed for high-draw appliances during backup events.
The 16S2P cell configuration (two 87Ah cells in parallel per series position) provides a higher capacity density per unit than single-cell designs at the same voltage, reducing the total unit count needed for mid-size residential and commercial installations. -
