#VICTRON BMV 712 BATTERY MONITOR INSTALLATION INSTALL#

My current simple install thinking is to put the shunt & Display inside the house battery compartment (under step). The Ugly - depends on how good you are at wiring. I am looking at purchasing the Victron BMV 712 smart battery monitor. You may need to do some charge maintenance on one set of batteries. I would make sure you have a Good Digital Multimeter and check the two battery voltages regularly. This will create some imbalances between both batteries over time. The Bad - The Positive and Negative Cables to your batteries are NOT the Same length. The Good - Now your Shunt will work correctly. I would HIGHLY recommend Redrawing the schematic (before you start) with your new plans and updating it with any changes durring construction. (It will probably be more messy than my description.) Now the only negative wire on the Lower Bank is the one that goes to Shunt (Battery Side).Īll of the negatives now flow through the shunt. The BMV-712 battery monitor comes with a 32-foot (10-meter) RJ12 cable, a 6-foot (2-meter) battery cable with a fuse, a square/round front bezel, a ring for. You may be able to re-use the 3/0 wire from 'Main Frame Grounding' to Lower Batt Neg. Move the 3/0 Black to 2000 watt inverter to the Busbar. Move the White 8GA from Solar Panel A to the Busbar. Lower Battery Bank: The only Negative cable should be the 3/0 Black that goes to Shunt (Battery Side). Now All the Negatives to the Upper Battery are landing on the busbar. The 3/0 Main Frame Ground to Upper Negative needs to be moved to the busbar.Īlso move upper 3/0 Black to Inverter Charger to the Busbar.Īnd the 8 GA White that goes to solar B need moved to the Busbar. Also run a 3/0 wire to the Lower Battery Negative (This is also connected to the Shunt (Battery Side). Add it near the Negative terminals of the Upper Battery Bank, Next to the Busbar Add the Shunt Connecting on the Load side (with 3/0 wire or a copper bar).Ĭonnect the Shunt with 3/0 wire to the Upper Battery Negative.
