Albertronic B.V. (Moordrecht, the Netherlands) is a well known player in the field of Battery Management Systems (BMS) for Lithium Ferro Phosphate cells for use in electric vehicles. Many customers asked for a system to store solar-energy into LiFePO4-cells.

This unique system is called : '123SmartBMS' and it allows the end-user to store and fetch energy, without any worries. The system supervises the entire process, and signals with two relays ( charge y/n and load y/n ) if charging is allowed and if discharging is allowed.

This way, the lifespan of your expensive cells is greatly enhanced...no more over-charging and no more over-discharging.....voltage and temperature of each individual cell is monitored constantly.

But that's not all! Off course, going 'off-the-grid' means that you would want to be informed about the amount of energy stored. Right?
Or you would like to know, how much solar-current is flowing INTO your battery a this particular moment.....or.....how much energy is stored today, or how much you consumed....etc, etc.The board that is mounted on the last LiFePO4-cell has a Bluetooth-radio, and it provides all this information to you, wirelessly!

The 123SmartBMS-system is extremely modular.....whether you work with 12, 24 or 48 Volts or way beyond: it is NO problem. The storage capacity ranges from 0,1 kWh to 1000 kWh!

A standard set for 12 Volt consists of:

- one "IN"-board ( to be mounted on cell number 1 )
- two "CELL"-boards ( to be mounted on cell number 2 and 3 )
- one "OUT"-board ( te be mounted on cell number 4 )
- two 100 Amp current sensors

A standard set for 24 Volt consists of:

- one "IN"-board ( to be mounted on cell number 1 )
- six "CELL"-boards ( to be mounted on cell number 2 to 7 )
- one "OUT"-board ( te be mounted on cell number 8 )
- two 100 Amp current sensors

A standard set for 48 Volt consists of:

- one "IN"-board ( to be mounted on cell number 1 )
- fourteen "CELL"-boards ( to be mounted on cell number 2 to 15 )
- one "OUT"-board ( te be mounted on cell number 16 )
- two 100 Amp current sensors

Different current-sensors are available on request.
