    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.


    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 5kWh to the largest 20kWh. 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. 

    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.
