 **Important:** Many installers neglect this aspect.
-The inrush current when switching on the battery breaker onto the DC bus is huge. This can cause damage to the breaker over time. So it is a Freedom Won requirement that the DC bus is pre-charged before switching on the battery. This is achieved by switch on the AC input to the inverters – the inverters will use the AC power to pre-charge their capacitors. This will eliminate the huge inrush current. The MPPTs can also be used for pre-charging by switching on the solar panels supply to the MPPTs.

 ===== CAN Bus Wiring =====
-The connection of the Lite to the GX-device is extremely simple. A standard **straight through** CAT5e Ethernet cable is required of the desired length, with one end plugged into one of the RJ45 sockets on the Lite and the other end plugged into one of the CAN sockets on the GX-device. Note that the second RJ45 socket in each case must be fitted with an end of line 120Ω resistor. Two are supplied with each GX-device. If multiple batteries are installed in parallel the second RJ45 socket is used to link the next battery in the line onto the CAN Bus network. The termination resistor is installed in the last battery in the CAN Bus line. Refer to Lite installation manual for further information.

+**Note:** In the case of the Venus GX or Octo GX, if the VE.CAN ports (RJ45) are being used by MPPTs, the secondary CAN bus needs to be connected using the green terminal blocks.  If you require any information on how to do this, contact Freedom Won support at support@freedomwon.co.za

 Systems with both VE.CAN MPPTs and more than one Freedom Lite battery require a GX device with a dual CAN Bus.  The entire GX-device range with the exception of the Color Control GX and the GX built into the MultiPlus II GX have dual CAN buses.  In these dual CAN Bus systems, the battery will always run at the standard 500kbps while the VE.CAN bus will run at 250kbps.

+Where batteries need to be configured with a profile accommodating 250kbps baud rate for the MPPTs on the CAN Bus (the standard is 500kbps), the change can be made either:

   - the battery can be reconfigured remotely by Freedom Won with a local PC connected to the battery.
