B-LFP48-300PW
Designed for homes and businesses with higher energy demands, this wall-mounted LiFePO4 battery provides reliable energy storage, maximizes solar self-consumption, reduces grid dependency, and delivers flexible backup power with long-term performance.
Experience Smart Energy with B-LFP48-300PW
The B-LFP48-300PW is a 51.2V 15.36kWh wall-mounted LiFePO4 battery designed for residential and small commercial energy storage systems requiring higher capacity in a single unit. With over 8,000 cycles at 90% depth of discharge and a design life of more than 15 years, it delivers long-lasting and reliable energy storage performance. The battery supports most 48V inverters through a high-efficiency DC-coupled system design, features an intelligent multi-layer BMS, and enables parallel expansion of up to 32 units for scalable energy storage systems exceeding 491kWh.
Long Battery Life
The B-LFP48-300PW is rated for over 8,000 cycles at 90% DOD at 25°C — 33% more cycles than the standard PW series. For a system cycling once per day, this equates to more than 21 years of operational life, significantly lowering the levelized cost of storage over the system lifetime.
High Compatibility
This 15kWh home battery is compatible with most 48V inverter platforms, including Victron, Studer, SMA, and Growatt. It integrates into both new solar installations and existing systems upgrading from lead-acid or smaller lithium packs.
BMS Protection
The intelligent BMS monitors cell-level voltage, current, and temperature continuously, providing protection against overcharge, over-discharge, overcurrent, and short-circuit conditions. Communication interfaces support real-time monitoring through compatible inverter platforms.
Scalable Parallel Expansion
Up to 32 units can be connected in parallel, scaling total system capacity from 15.36kWh to over 491kWh. This makes the B-LFP48-200PW a practical choice for commercial facilities and large residences planning phased capacity additions.
15.36kWh Single-Unit Capacity
At 15.36kWh per unit, the B-LFP48-200PW provides enough storage to cover a typical household daily load in a single installation, reducing the number of units needed and simplifying both wiring and commissioning.
10-year Warranty
Every B-LFP48-300PW is covered by a 10-year product warranty, supported by BSLBATT global service infrastructure deployed across more than 100 countries.
