-===== Operating Philosophy =====+===== Victron-certified Integration =====
  
-The Freedom Lite transmits, amongst others, the following messages to the Venus device:+The Freedom Lite transmits, amongst others, the following messages to the [[https://www.victronenergy.com/live/venus-os:start|GX-device]]:
  
-  - Adaptive Maximum Charge Voltage Setpoint – the value transmitted varies from 54.1V to 55.8V depending on the state of balancing on the particulate Lite. Typically a well-balanced Lite battery will request a maximum charge voltage of between 55.0V and 55.8V. This advanced feature is only available from Freedom Won and allows superior system control and optimal battery management. The Venus device uses this setpoint to control the real time operating or target voltage of the inverter/charger devices and the MPPT’s.  +  - Adaptive Maximum Charge Voltage Set-point – the value transmitted varies from 54.8V to 55.8V depending on the state of balancing on the particular Lite.

This advanced feature is only available from Freedom Won and allows superior system control and optimal battery management. The GX-device uses this set-point to control the real time operating or target voltage of the inverter/charger devices and the MPPTs.  
-  - Charge Current Limit (CCL) – this is the maximum current that the battery will accept at any given time stated in Amps. This is a secondary control feature behind the more effective maximum charge voltage control method. This value reduces as the battery approaches 100% State of Charge (SoC). The Venus controller uses this value to ensure that the combined Victron system of inverter/chargers and MPPT’s does not exceed the CCL of the Lite. If the CCL drops to zero, the Victron system within a few seconds will ensure that there is no net current flow into the Lite.  +  - Charge Current Limit (CCL) – this is the maximum current that the battery will accept at any given time stated in Amps.

If the CCL drops to zero, the Victron system within a few seconds will ensure that there is no net current flow into the Lite.  
-  - Discharge Current Limit (DCL) – this is the maximum discharge current that the battery is prepared to accept at any given time. This value typically decreases as the battery drops below 10% SoC. The Victron inverter cannot enforce a variable DCL unless in ESS mode were an AC input source can be used to supplement the power to the loads. If there is no AC input source the inverter will stop supplying power to the loads as soon as the DCL drops to zero.  +  - Discharge Current Limit (DCL) – this is the maximum discharge current that the battery is prepared to accept at any given time.

 If the CAN bus cable is removed or damaged the Victron inverters will shut down within 5 minutes. This prevents continued operation in the absence of communication from the battery. Likewise, the MPPT’s will stop producing power to the DC bus.  If the CAN bus cable is removed or damaged the Victron inverters will shut down within 5 minutes. This prevents continued operation in the absence of communication from the battery. Likewise, the MPPT’s will stop producing power to the DC bus. 
 +
 +===== DC Bus Pre-charging =====
 +
 +**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 switching 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 ===== ===== CAN Bus Wiring =====
  
-The connection of the Lite to the Venus 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 Venus 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 Venus 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.  +The connection of the Lite to the GX-device is extremely simple.

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. 
-Correct CAN Bus communication can be verified by observing whether the Freedom Lite battery is presented in the Venus device list under the name Freedom Lite.+ 
 +**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

 +Correct CAN Bus communication can be verified by observing whether the Freedom Lite battery is presented in the GX-device list under the name "Freedom Lite". 
 + 
 +===== Victron VE.CAN MPPTs and Freedom Won Batteries ===== 
 + 
 +**Note:** In this section, the reference to "Color Control GX" refers only to that specific model of GX device and excludes the rest of the range.  The limitations described in this section apply only to the Color Control GX (CCGX). 
 + 
 +The Freedom Won Battery Management System is configured by default to communicate over CAN bus at a 500kbps baud rate. For systems using a Color Control GX and Victron VE.CAN MPPTs, it is possible to change the baud rate of the battery to 250kbps in order to accommodate the VE.CAN baud rate. **However**, that is only possible with one battery on a system with a CCGX. 
 + 
 +If there are slave batteries on a system, then there are conflicting CAN messages on the bus, and it is necessary to split the battery on the CAN Bus from the devices on Victron's VE.CAN bus. The Color Control GX has a single CAN bus and thus this split cannot be achieved.  Therefore, CCGX **cannot** be used in systems with multiple Freedom Won batteries.  In such cases, MPPTs must be swapped out for VE.Direct versions and [[https://www.victronenergy.com/live/ccgx:start#power|additional ports can be provided with a USB hub]] (See "Extending USB ports by use of a self-powered USB hub").  Alternatively, the CCGX can be upgraded to something newer like the Cerbo GX and external display. 
 + 
 +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: 
 +  - at the time of ordering by requesting that Freedom Won dispatches the Lite from the factory with baud set to 250kbps; or 
 +  - the battery can be reconfigured remotely by Freedom Won with a local PC connected to the battery.
