The App

First connection

Go to the App store for Apple devices and
search for "123SmartBMS". Install the
123SmartBMS App on your Apple device. For
Android devices go to the Play store and
search for "123SmartBMS". Install the App on
your Android device. Enable the Bluetooth
functionality of your device.

bottom corner to open the settings section.

App Settings

Solar peak power: Set the maximum power of
your incoming energy source, for example
solar panels. If the system contains 10 solar
panels of 250 Watt each, the total power of
2.50 kW has to be configured.
Inverter peak power: Set the maximum power
of the consumers, for example an inverter.
When your inverter can supply 5 kilowatt,
5.00 kW has to be configured.
Battery capacity: The battery capacity can of
course be set to the total capacity of the
battery pack. We advise however to take only
80% of the rated capacity, to comply with cell
aging and temperature effects.
Example: If you use four 200 Ah cells  4 x
200 x 3.2 = 2560 Wh. In this case we advise to
use a value of 2560 x 0.8 = 2048 Wh  2.0
kWh.
Current sensor: Please set the current sensor
type you are using. The standard current
sensors supplied in the set are dual range
500A – 20A.
Critical mode:

minimum cell voltage threshold the "Vl"
warning indicator on the battery details
screen is switched on. The "allow to
discharge" relay to control external devices
will be switched off.
V max: If one of the cells gets above this
maximum cell voltage threshold the "Vh"
