    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    In this case that is very true.. I would have never found out in time and have a thermal runaway event.. that would be a very bad day.. Being able to see the voltage delta is actually an interesting metric for resistance on the circuit.

    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    I think the mystery has been resolved.. the positive cable coming out of the MPPT was getting very hot so it was increasing the resistance. Here is the offendfer. Now I have replaced this part with a properly sized one and disabled the DVCC feature (for testing). Now the voltages are almost...

    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    HI there! quick update.. I enabled DVCC and indeed now the MPPT gets the voltage from the Shunt and applies the correct charging profile. I still need to verify all my physical connections and fuses for any high resistance or loose connections but in terms of settings, it is looking good now...

    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    I do have some mid priced fuses in line.. will check! thanks for the feedback!

    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    I couldn't agree more! I discovered the victron world recently for my new boat and I am so happy with it! I cannot recommend it enough. And I love that they allow you to run their official software on a ras-pi. Great consumer friendly policy

    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    Hi all, Wow! that is a lot of information very quick!! thanks so much! I'll take these actions and come back with additional data. Also I should have clarified (and maybe added it to my diagram) that I am running the GX software on a raspberry-pi so the shunt and mppt are connected via usb...

    My Victron MPPT reports higher battery voltage and goes into Absorption and Float prematurely.

    Hi all! I am new to the forum, so thanks for having me :) I am experiencing an interesting issue on my off grid boat setup. I use a Victron MPPT charger for my main 24V solar array (2 x 170 watts). I also have a second charge controller with a portable 24v solar array ( 2 x 50watts) that I...
