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.
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...
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...
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
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...
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...
