HI
I currently have the following system
Invertor - KH10
Battery ECS4800 - 1xCM4800 and 3x CS4800 (Capacity circa 19kwh)
i'm looking for assistance and details on what is involved in adding in additional 3 off CS4800 slaves to increase the battery capacity to max (32kwh).
Is it simply power down , remove Master, add in the new slave modules and power up as it infers or is there more to it and other considerations etc
thanks
Yes not far off with that, you must add CS4800 slaves and the pack must be at 50% (+/- 3%) when you add the new batteries.
The lowest battery has a plug fitted to terminate the batteries and it is always advisable to add new batteries to the top of the stack, so yes remove the Master and then add the new batteries, replace the Master and start it up.
You will need to update the firmware on the pack so that all batteries are running the same (latest) versions, if you have installer access you can do that your self, or you can ask an installer to do it, or alternatively raise a support ticket with Fox and ask them to update your battery firmware to the latest version.

Hi Dave
i have now sourced and installed the additional 3off CS4800 slave units . before i power back up i wanted to check.
adjacent to the battery isolator there is a din switch 0 to 7 . it is currently at 0 from the original installation . I can see no reference or instruction to make any adjustment to this . See image attached
i did see a video of a supplier showing the install and at the end they changed din dial associated with the total amount of modules installed
Can you confirm if i need to make any change to this
also just to check the power up sequence .
for shutdown i powered down the invertor and grid supply and then isolated the Battery
for power up i have been told that i power up the Invertor and grid and then start-up the battery
can you confirm this is correct or otherwise.
appreciate the assistence
thanks

The rotary DIP switch is no longer used the master will scan the batteries at startup and establish the number of slaves fitted - it should be left set to 0.
For power up, everything should be off to start - then it is battery on first, wait 10 seconds for it do do it’s scan and it will close it’s battery contactor which will provide power to the inverter so you should see the inverter screen light up and turn to checking/waiting.
Then turn on the AC isolator/MCB so the inverter is connected to the grid - the inverter will continue to go through it’s checks with various clicks, after approx 1 minute it should make 1 final click and then go steady with ‘Normal’ on the screen.
You can now close the PV/DC isolator and you are back up and running.
