How to control a Redback hybrid SH5000 inverter/charger with a WatchMon

Here are the steps to configure the Redback smart hybrid SH5000 inverter/charger to the WatchMon supervisor.

CAUTION:  Example below has values shown for a demo LiFePO4 cell pack, ensure that you adopt values suitable to your application and comply with the battery suppliers recommendation.

Step 1 - Install communication cable to charger via CAN1 port on WatchMon.

For newer WatchMon (note 120 Ohm resistor shares CANbus High and CANbus Low

For older WatchMon with 4 pin CAN see below

Step 2 - Install communication cable to Reback BMS socket (extract from  manual)

Typical Cat 5 cable colour pin combination.

Redback  RJ45 pin 7 (typically Brown/White)connects to Can-H WatchMon
Redback  RJ45 pin 8 (typically Brown) connects to Can-L WatchMon 

Redback  RJ45 pin 1 (typically Orange/Green)connects to WatchMon GND

NB: Using a CAT5 ethernet cable strip back the cable and connect to pins identified above.

Step 3 - Navigate to Hardware, then Integration tab.

Step 4 - Select Canbus protocol to "Redback Hybrid SH5000" and Save.

Step 5 - Navigate to Control Logic, then Charging tab.

Step 6 - Adjust the charging control logic to suit the application.

Notes:

• Low power must be enabled.
• Cell Hi Cutout should be above the CellMon bypass voltage threshold as a safe guard target.
• Low power current should suit the bypass capability of CellMon.
• When the bypass current is above Initial will trigger the system to low power.
• When the bypass current for all cellmons is above Final the system will complete charging cycle.

Step 7 - Navigate to Hardware, then CellMon tab.

Step 8 - Adjust the CellMon bypass voltage to suit the application.

Note: Make sure to "Device Sync" the changes to the CellMons.

Step 9 - Navigate to the Remote tab on the Control Logic screen. 

Step 10 - Adjust the remote charging target to suit the application.

Notes:

• Scaling must be 10 for both voltage and current.
• Low power must be enabled on charging tab.
• Low power current should suit the bypass capability of CellMon.
• Charger voltage target needs to be sufficient for all cells to reach bypass threshold.

Step 11 - Adjust the remote discharging targets to suit the application.

Notes:

• Scaling must be 10 for both voltage and current.
• Do not run low power mode on discharging tab.
• Control logic discharge voltage cutout should match the remote target.

Step 12 - Navigate to Telemetry, then Live Stats to observe system operation.
