Multis connected three off in three phase system
Multis connected three off in three phase system
Hi Guys!
I have experienced the same problem today on installation. As soon as I connect the RJ45 cable from the VE Bus of the CCGX to the VE Bus on the multi 3000, the multi switches off within 3 seconds. I have updated the multi and the CCGX to the latest firmware, but it haven’t made a difference. I also changed the RJ45 cable with a new one.
Any feedback please?
What did you try already?
did you read all comments in this thread?
Hi Boekel.
Yes I have tried all of these comments. As soon as I insert the RJ45 cable connecting the CCGX and the multi, the inverter kicks out. But it does not stay off, it tries to restart but as soon as it kicks in, it kicks out again. Only when the network cable is disconnected, the inverter runs smooth.
does it show up in the device list?
if not maybe contact your distributor to find out what is wrong.
Hi
Out of interest is this the same system you have had the error 17’s on?

Hi Mike.
No, my system only has one inverter installed. I think an error code 17 only applies if there is a slave inverter.
I think my inverter has an issue on the network card, that is why it kicks out when connecting the CCGX to it. Will let you know.

Hi Dionne, does the CCGX show the Multi’s in the device list?
Cannot see as the inverters turn off immediately when the ve bus cable is connected
The CCGX can take control of a system once connected, including turning it off. In my experience, if all components (CCGX and Multi’s) have been updated to latest firmware they will cooperate nicely. Have you done the basics, including changing out the RJ45 cable?
Yes changed cable no difference
As soon as you disconnect the vebus cable the inverters turn back on ?
If the inverter turns off, it should still be visible in the device list, and you can turn it on there.
Are there any other VE.bus devices in the system? (BMS, control panels, etc.)
Like this:
If the MultPlus is not 'detected' & shown in the device list then you could try either of the two actions below that normally sort out any communication/detection issues;
1- With the MultiPlus switchd ON select 'Re-detect System' (in the MultiPlus menu)
2- With the MutiPlus switched ON 'Reboot' the CCGX (under Settings -> General > Reboot)
