Hello,
We have an installation with 4 VE Direct MPPTs and an Octo GX. 3 of the 4 MPPTs are in a constant off state as shown in the photo. Second photo shows that they have an appropriate PV voltage and the battery SOC is only 30%.
We have tried switching the VE direct cables and also different VE direct ports on the Octo but it is always the same 3 units in the off state. The firmware was updated on all units and there is no error state on any of them.
Any ideas?
I am the engineer who was on site when this problem occurred. On the remote console connection, under the device parameters for each of the MPPT’s the connection states USB. This should be VE Direct. I believe that the MPPT,s are on the USB Bus not the VE Direct Bus. Anyone have any ideas how to rectify this?
Hi @Stevo07
Engineer logged on to the Octo, the mppt's state the 'remote input' is not ok, can it be the remote bridge connection is missing?

Apologies, there was some site glitch and some of your follow up comments were lost. This is as best as I could recover. I have reported the bug.
@Stevo07 : This fixed the issue, many thanks! It was not immediately obvious that this should be checked, do you know where this info is contained?
@Daniël Boekel (Victron Energy Staff) : It is in the start up procedure in the MPPT manual, under cable connection sequence. It also comes connected from the factory, so someone has removed it.
Is the charger enabled in Victronconnect?
A disabled charger will show an "Off" state in Venus.
