Cerbo GX shows wrong Quattro input for Input Current Limit

We have installed two independant Quattros connected to a CerboGX. One through VE Bus and the other through MK3 to USB adapter.

Both Quattro units have Shore power on AC Input 2. One has a generator connected to AC input 1. AC input 1 (generator) is set to 40 amps and "Controlled by remote" is disabled. AC input 2 (Shore power) is set to 32 amps and "Controlled by Remote" is enabled.

On VRM on remote console I can see "Input Current Limit" is 40 Amp. It cannot be adjustable. I cannot see the 32 amp input current parameter.

On the Garmin MFD I can see Input Current Limit is 32 amps. Not yet sure if it can be adjusted but will know tomorrow afternoon. I hope so.

It appears the CerboGX is displaying the wrong input. It appears to be displaying the input disabled from adjustment rather than the input which is enabled for adjutment.

Has anyone else seen this? Cerbo Firmware V2.75. Is this a software anomoly or have I somehow misunderstood how this works.

I have now confirmed the Garmin MFD does show the correct input current limit and it is adjustable and works as it should. That is very good but the Cerbo GX through the Touch 50 shows the wrong input which of course is not adjustable anyway. It seems this is a software error unless I have misunderstood the purpose of the Cerbo gx readout. Had we not interfaced to the MFD we would not be able to adjust input current limit.

As an addendum to my previous two posts, when input voltage is presented to the Quattro on the AC 2 input, the correct input current limit does appear on the remote panel. I think it is strange for the non-adjustable current limit to be on the remote panel until the input voltage appears on the mains input, then the adjustable one appears. It may be better for the adjustable one to appear always to avoid confusion. Having said that, the system we are using it on is relatively complex and the facilities we are using on this installation are just simply awesome.

I see the same thing with my setup. I coulda sworn it wasn't always this way, but trying to set up the boat now, on anchor, to get ready for a boatyard to take it tomorrow and plug it into 15 amp crappy power, I now have to get my PC out and use Victronconnect to set the shore power limit for tomorrow. :(. Bad design. The phone app through activecaptain can set 10/15/etc. but not the 13 that's the actual min limit.

I have the same problem on the gx touch is there already a solution?

Its verry frustrating for the costumer.

Or is this problem on the to do list?

I started using guimods a while ago, and the interface to change current limit works fine in that. So no idea if they changed it in the base Cerbo at this point or not.

Thank you. I whas also looking into that at the moment.

Is it stable enough for an end user?
