Switching on the Lite
The Lite is fitted with an “ON” button. Press this button for at least 5 seconds to switch on
the BMS inside the battery. Once the BMS has been energised you will observe the SoC
display come to life with the SoC level shown. Confirm at this stage that the error lite is not
illuminated. If it is, contact Freedom Won. If the Reduced Power light is illuminated, do not
be concerned, it should extinguish after the battery has been in operation for a few hours.
Once the BMS has been energised, the main breaker may be switched on by pushing the
breaker upwards. Ensure beforehand that you have secured the DC cables to their proper
locations and that the rest of the system is ready to receive battery voltage.
Note: On some inverters there is a large inrush current when switching on the DC supply. IT
is important in these instances to pre charge the DC bus. With Victron this can be achieved
by switching on the PV to the MPPT’s to allow them to apply voltage to the DC bus before
closing the battery breaker. If this option is not available you can switch on the AC input
power to the Victron inverter as this allows the inverter to place voltage on the DC bus. If
you are using inverters that cannot do this you will need to use a pre charge resistor.
To switch off the DC output from the Lite, pull down the breaker. To switch off the power to
the BMS, press the “OFF” button situated to the right of the “ON” button. This will also trip
the breaker if it is still on at the time. The Lite must be switched off fully when not in use to
prevent self-discharge.

Settings Required for Setting up Inverters and Charge
Controllers
The maximum and continuous discharge currents for the respective models are provided in
Table 2.1. For charge current settings the same limit can be used as the continuous
discharge current, however this is usually not possible owing to limitations of the charger or
