-===== Color Control GX / Venus GX Interface ===== 
- 
-The Redflow ZCell BMS supports the same CAN-bus protocol connection to the Color Control GX that is used with many Lithium Battery BMS systems. ​ 
- 
-The best way to interface from a Redflow battery system to the CCGX is to use a canbus connection on the ZCell BMS and to follow the Color Control GX canbus interface procedure as for any other CAN-bus BMS based battery. 
- 
-The [[https://​www.victronenergy.com/​live/​ccgx:​start#​dvcc_-_distributed_voltage_and_current_control|Distributed Voltage and Current Control (DVCC)]] feature provides excellent outcomes and provides very tightly integrated operation and control. The use of DVCC is normal (and highly recommended) for all new ZCell/ZBM2 installations. 
- 
-A deprecated MODBUS-TCP interfacing approach [[https://​faq.zcell.com/​content/​10/​55/​en-us/​enabling-state_of_charge-update-using-modbus_tcp-with-a-ccgx.html|is on the ZCell website]]. This can update the SOC on the Color Control GX using MODBUS-TCP over ethernet instead of using CAN-bus as the interface mechanism. For installations that are not using DVCC, you should limit the maximum charging voltage for all charging elements in the system to 56V.  
- 
-This page on the ZCell web site explains how to interface and configure a system to use ESS (if needed) and to activate DVCC:

- 
-Important Caveats: 
-  - At present when DVCC is turned on for Redflow ZBM2 based installations,​ it is required to turn the SVS (Shared Voltage Sense) function OFF. The SVS option appears under the DVCC item after DVCC is turned on. This limitation may be removed in a future DVCC release. 
-  - For successful operation on-grid of Redflow ZBM2 systems with the Victron Energy [[https://​www.victronenergy.com/​inverters-chargers/​multigrid|MultiGrid 48 product series]] (with AS4777 grid approval) in Australia, the minimum MultiGrid-I vebus firmware revision required is version 424 and the minimum for MultiGrid-II models is firmware version 425. Please read this [[https://​faq.zcell.com/​content/​10/​67/​en-us/​installing-a-victron-energy-multigrid-with-zcell-systems.html|Redflow FAQ page about MultiGrid interfacing]] for further information about how to install a MultiGrid product onto a grid connection in Australia. 
-  - For successful black-start using VE.Direct MPPT units as the sole startup energy source with DVCC enabled, the VE.Direct MPPT units //must// be running Firmware version 1.30 or later. ​
