BMV-712

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.

Newly installed: It’s clear that someone at this company understands human centered design because there is a lot of thought that has gone into just about every aspect of this device. The shunt was easy to install, and has very clear markings on which side to connect. I was able to put it into a large battery box (see photo). The voltage tap they provide has an actual Ferule crimped on it for inserting into the spring connector on the shunt. This is a detail I have only seen on professional factory equipment for handling vibration connections. It’s exactly the right way to do it. Bravo for this. The display module itself is pretty tight and well designed. The buttons are intuitive and function as you would think they do. My only complaint is that trying to create readable text from 7 segment elements is hard to read. It took me a while to figure out what was being displayed. It would be better with a dot matrix style display. But I get it, cost and all that. The app almost makes up for this, except for the purist in me that doesn’t want a phone when I’m camping. The app is really where this device shines. As a hater of Bluetooth, I was surprised how easy the initial connection was. It basically just connected and worked. The app is quite frankly great in its simplicity. I am particularly fond of how clear and concise the presented information is. It definitely passes the 5 second test for human dashboard consumption. Marvelous. Also, I can actually connect to the device from my house, if I need too. Which is just amazing. Other items of note. The included square bezel is great. The quality of the cabling is good. There is a connector on the back for adding their other display. This company released the protocol documentation as well which is a huge plus. I’ll update the review when I use it more, but this thing is a solid 5 stars for me. SUPER happy to see a well thought out, and well executed device like this. As an embedded software engineer myself this sets the bar for me. Totally worth it.

Excellent piece of gear for keeping track of your RV batteries. Well designed, built and equally if not more important, the app software is easy to use and integrates nicely with other Victron devices. Note the included 500A shunt has an IP21 rating meaning it is not waterproof and must be mounted in a dry location. As it should be close as possible to the batteries, I mounted our BMV-712 in the battery compartment under the RV entry steps which is partially open to the weather (road below) for ventilation of battery gasses. Given that, I purchased this small Hrensaw water-resistant electrical box (https://www.amazon.com/dp/B0C5X3DJ1Z) to enclose and protect the shunt. Worked like a charm.

Victron nailed it with this one. I use it to monitor a LiFePO4 bank in an off-grid setup and the readings are incredibly accurate. The Bluetooth app is intuitive and offers deep insights like voltage history, amp draw, SOC, and more. Setup requires a little patience (especially shunt placement), but once it’s running, it’s a game changer. You’ll always know your battery’s real status.

Victron is always a safe choice

Tells you the state of battery charge.

Tolles Teil. Stellt alles gut da. Bedienungsanleitung und Anschlussplan sehr gut. Mittlerweile gibt's aber auch gute Alternativen.
