I also got an in-app alert telling me my battery was running low. Once the battery hit 10%, the alarm’s buzzer went off and the screen started flashing. And you can even adjust what specs the screen has in its rotation in the app. The screen shows one spec at a time, but you can easily cycle forward or backward through them by pressing the plus or minus buttons. There is also a time remaining estimate which is helpful if the power draw is more or less stable. Both show all the specs of interest: battery voltage, battery amp hours, battery percentage, charging or discharging current and wattage. I monitored the discharging with the app and screen. Then I set the BMV-712’s alarm to go off at 10% capacity. Once I’d set up the monitor for my 12V 100Ah LiFePO4 battery, I connected a 2000W inverter and started discharging the battery at a 0.2C rate (i.e. There are also options to adjust settings for the monitor’s additional features, such as the alarm and relay. You can see cumulative totals for things like amp hours charged and discharged, and trends reports for things like current and wattage over time.įor advanced Victron users, the app is also where you can set up Victron’s VE.Smart Networking to connect the BMV-712 to your other Victron devices.

Once you adjust a setting in the app, it will automatically sync with the monitor and its screen. There are also lots of good YouTube videos out there on how to set up this monitor. The product manual is a little dense but a great starting point. The battery settings can be a bit confusing at first, and I think some people’s initial instinct is to input the basics, like capacity and state of charge, and be done with it.īut there are lots of great resources out there to help you pick the right settings for your battery. Here you’ll see a long list of settings you can adjust. Tap the gear icon to go to the settings menu, then tap “Battery” to get to the battery settings. And, assuming nothing is connected to the battery other than the monitor, all the other values should read zero. The percentage field may be empty because the monitor doesn’t know how charged your battery is. Once connected, you’ll be taken to the “Status” screen that shows you your system’s real-time specs - things like battery percentage, voltage, current, and wattage. Open the app and follow its instructions to connect the BMV-712 to your phone. It’s easier in the app, so that’s what I did.

Lastly, if you can’t or don’t want to drill a hole in your wall, you can buy Victron’s wall-mounted enclosure, mount the enclosure to the wall, and then put the screen inside that. Second, you can use the included mounting plate and screws to mount the screen that way. The drawback to this method is that it requires you to get your hand behind the wall, which isn’t always possible. The screen can be mounted in 3 ways, which gives flexibility compared to other battery monitors whose screens can only be mounted 1 way.įirst, you can use a 2 1/8″ hole saw or slightly bigger to drill a hole in the wall and then screw the included mounting sleeve on the back to hold it in place. Or you can use a drill and 2 screws to mount it to a wall. To mount the shunt, you can tape it to a surface, such as the top of a battery, using double-sided mounting tape. It’ll make installation and setup a lot easier. Before installing, I recommend disconnecting everything from your battery and charging it to 100%. The Victron BMV-712 has 2 parts that require mounting: the shunt and the screen. Victron BMV-712 Smart Review Installation
