Product Description

B-LFP-15PW

15 kWh BSLBATT Lithium Powerwall Battery

OPTIMIZED SOLUTION FOR ENERGY SAVING & HIGH-QUALITY POWER


Energy Storage System(ESS) stores electric energy and utilize them for later consumption. It is purposed to improve energy efficiency, by enhancing the quality of renewable energy that results stabilization of power supply system. BSLBATT Lithium provides most optimal energy solution for the users using our state-of-the-art energy storage system with a long lifespan and a top-notch quality.

CONTROL INTERFACE FOR COMPATIBLE INVERTER/CHARGER UNITS:


The BMS provides relay and analogue outputs and CAN Bus for independent control of (and communication with) the inverters and solar charge controllers through a multi core cable and Ethernet cable respectively. Charge and discharge current limits and state of charge values are some of the important parameters transmitted by the BMS. The Lite is configured prior to delivery for the applicable inverter brand.


SAVE UP TO 25% ON YOUR UTILITY


When paired with solar, the BSLBATT lithium Power wall is the perfect way to automatically save money while paying the lowest possible cost for your energy.

Expensive?

Lithium Iron Phosphate batteries might seem expensive when compared to lead acid batteries, but this is not true. A proper scenario comparison will reveal that the purchase costs are very similar and any marginal premium for a LiFePO4 battery is more than compensated for by longer life, and a very high efficiency. The high efficiency means that far less energy is wasted and that the solar array can be 30% smaller to achieve the same results. In general - because of the high DoD capability and high efficiency the ampere hour rating of a BSLBATT Lithium Battery need only be 35% of a lead acid battery to give the same useful output - this is important when comparing costs between the two technologies.

Compact, Integrated and Attractive:

The BSLBATT (LiFePO4) Home and Business batteries range covers the varying needs of home owners and small to medium business premises with models ranging from the B-LFP-2.5PW to the largest B-LFP-20PW. The “Home” models are wall mounted offering the ultimate in space saving. All models are integrated with the necessary Battery Management System (BMS) and control circuitry to protect the pack and interface with the seperately supplied external inverter/charge units. The standard enclosure is powder coated in white.

Power Interface:

Suitably sized positive and negative cables are provided for connecting the 48V DC cables to the inverter and solar charge controller. The DC circuit is protected with a shunt trip circuit breaker.
