You use the buttons to set the total amp-hour capacity of your house battery.

The setup of the battery monitor is very simple. I’m not all that happy with this, and will probably replace the terminals on the wires with ones that are compatible with the larger bolt on the Victron shunt. The copper is a flattened piece of 3/4 inch copper pipe. It would have been nice to just move all of the wires on the negative terminal of the battery onto the shunt terminal, but Victron uses a larger bolt for the shunt terminals, so had I put in copper bar with all the wires coming into one end of it, and the other end attached to the shunt.

This is something to think about if you want to be able to install a battery monitor at a later date. I would like to have put the shunt right next to the battery, but there was not room for it there, and I had to install it just outside the battery box.

There is also a small wire that goes to the plus terminal of the battery to the shunt that supplies power to the meter. The shunt must carry all of the current in and out of the negative terminal of the battery so that it can accurately sum up discharge currents and charging currents into the battery from chargers or the van alternator or solar - so, all of the wires that now go to the negative terminal of the house battery should go to one end of the shunt, and a single wire should go from the shunt to the battery negative terminal.Ī small cat 5 sort of cable then goes from the shunt to the Victron meter. The installation requires adding a shunt into the negative lead of the house battery. I have to say that while the battery monitor is by no means a must have, it does provide information that is useful and nice to know. The first trip after installing the battery monitor, we kept track of state of charge each day (as well as water and propane used).

Since it knows the full amp-hour capacity of the battery and it knows how much current has come and gone from your battery since full charge, it can calculate at any time how much of the total capacity remains. It then starts to monitor and sum up over time all of the current going out to loads in the RV and all of the current coming into the battery. The battery monitor works by first sensing when the house battery is fully charged. It also allows you avoid running your battery down to a low state of charge, which is hard on battery life. This tells you at a glance how much juice your battery has left. The value you will probably use the most is the State of Charge. The various values are accessed by pressing the + key. The Victron displays SOC (State of Charge) as a percentage, remaining hours of use, amp-hours used since full charge, electrical current going into or out of battery, and battery voltage. The monitor we decided on is the Victron 700.

This helps you decide when your battery needs a charge, whether you are likely to still have some juice left in the morning, and helps you avoid discharging your battery too deeply (which will shorten its life). Basically, the battery monitor lets you know how much juice is left in the batteries - i.e. We decided to add a battery monitor to our conversion van camper.
