Yes, correct. The first test in fact I increase +2v in the MPPT (54v máx) but the MPPT continues to enter in float with the ve.direct disconnect… I don’t know if is necessary to power off 100% the MPPT or reset internal, because is controled by BMS and possible when disconect the ve.direct cable, he stops because not comunication with VenusGX is find… I need to read in detail the MPPT manual…
Correct and the system is working with the DVCC Victron/Pylontech comunications. Like you can see, the DVCC is force by the VIctron/Pylontech shake hangs.
I don’t change any firmware in the Pylontech. They are with the same firmware from the beginning:
Could you pls post updated status and settings of the mppt, I’d like to get around this 
I write the information in the Graph only to be more clear of what to expect (change the numbers… is 53.2V, sorry). This value is confirm in VenusGX → Battery → Parameters and I think is a result of the predefined parameters of the Victron configuration for Pylontech (BMS talks).
Inclusive we can confirm the charge limit voltage working, on an previous day (when I was out of home, low consumption and a lot of sun). The SOC goes to 100% but only because the MPPT 250/60 is working well… The MPPT250/100 shutdown the production because of the +2v (I think), or Victron have some algorithm to make this charge profile 
I’m an noob, so I’m slow to ready the link and see how can I make the test document in the link.
Your main problem is the different battery voltage showing in the mppt’s, once this is resolved everything else should work again
If ve.direct is not connected and no “smart” bt network active the display should have the voltage of the terminals.
If not → get a new one.
The PDF for you may be easier.
It is really just a way to work through methodically. You have already by nature done one of the tests by independently checking terminal voltage.
If you are just out of warranty though I am not sure how that will be handled by the parties you are working with.
Hi @PMB
It sounds like you’ve done everything needed to confirm a fault with the MPPT. Have you taken your documentation and test results to your Victron dealer to see what can be done?
It may be better to submit a warranty claim now even if it’s refused, rather than wait any longer.
They might still be able to help, perhaps with a discount on a replacement.
Only to be clear with the measures:
MPPT250/100
MPPT250/60
The physical connection in the MPPT250/100:
MPPT battery → Lynx bush bar. No sign of oxidation (indoor installation) and burn marks…
MPPT250/60 have the same cable configuration.
Thanks for the information. In fact warranty is pass from 8 months and because of that I don’t report directly to the dealer…
I will report now and see what happen.
Thanks very much.

Hi PMB
I understand your frustration - We had a similar situation where the 250/100 incorrectly reads the VBat voltage as to high and then stops charging the batteries.
It took me 3 months and assistance of Victron developers to convince Victron Support the device is faulty (3years old), and needed to be replaced under warranty.
good luck
