I'm a total tech illiterate, does it come with everything one needs to fully install the meter or one has to purchase other things as well? thanks

Hello, C. As I recall, everything you need is included. You will have to connect it to your battery bank, mount the shunt nearby and run the included wire from there to the monitor itself. There is probably a .pdf on the Victron website that has everything you will need to know. It's a very well made device and worth the higher price. Best wishes!

My house batteries are up under my E-350 van, and are therefore exposed to the elements while driving along. OK for the shunt to be down there, too?

There is a RJ-45 connection that is not intended to get wet, so having it in an unprotected location is probably not a good idea, especially if road salt could get to it. If you can bring the battery negative cable into the van, that would be much better, or else use a weatherproof junction box.

I have two 12v 31-series agm batteries wired in parallel. can anyone provide info on how the negative from the battery should be wired to the shunt?

After the two batteries are connected together, the negative from one of them goes to the shunt, and nothing else. The other side of the shunt goes to the negative bus bar, chassis ground, etc. It's important that no loads or charging devices connect directly to the battery negative, otherwise the flow will not be monitored by the shunt.

I have just installed a victron 75/15 mppt & would like to install a display that does both 1) display battery level 2) show solar panel live status

The monitor will show current state of charge of the batteries. You can then scroll to the current inbound or outbound power in amps. The number will be plus showing net power from the panels minus current load. I hope that helps.

Très bon produit de qualité indispensable

Vraiment très pratique pour le surveillance d’un système de batterie dans un camping-car. Il est ainsi possible de surveiller les paramètres des batteries cellule et de la batterie porteur. Ces batteries peuvent être de technologie différentes (lithium / plomb) sans que cela pose de problème. Enfin grave à l’application et à la connectivité Bluetooth toutes ces informations sont disponibles sur son smartphone, un vrai plus

Rock-Solid System – Completely Transformed My RV Experience

I’ve been running a full Victron setup in my RV since 2021, including the MultiPlus inverter/charger, the SmartSolar 100/30 charge controller, the BMV-712 battery monitor, and the Digital MultiControl panel. After years of use across various climates and conditions, I can confidently say this system has been absolutely rock solid. Each component was easy to install and configure, and the integration between devices is seamless. The MultiPlus handles all of my AC needs flawlessly, switching between shore power, generator, and battery without a hiccup. The SmartSolar charge controller keeps my solar system optimized and running efficiently, even on cloudy days. The BMV-712 gives me precise battery monitoring at a glance, and the MultiControl panel makes managing the inverter simple from inside the RV. What I appreciate most is how this system has given me real freedom. I can boondock for days without stress, knowing exactly how my batteries are doing and trusting that the system will just work. It’s added reliability and convenience that truly changed how I RV. Highly recommend Victron to anyone serious about upgrading their mobile power setup. Worth every penny.
