You probably have invested the mod-time and mod-money to upgrade your battery bank and charging system, then you definitely also needs to invest in a battery monitor. There are a variety of monitors available masking a broad range of features. A simple volt meter can shortly inform you at a look what your battery low voltage disconnect is and subsequently the assumed p.c of charge remaining. This generally is a bit misleading although since voltage alone would not tell the entire story. A simple voltage reading would should be performed when there is no load on the battery for a minimum of 24 hours to get an accurate reading. This is not very practical and probably not something you'll want to do frequently.

What is required is a solution to tell how a lot capability you've left in your battery bank, very similar to a car's fuel gauge. At a fast glance, you can see how a lot gasoline you could have left so you already know when to fill up. Battery displays work much the identical way. Not solely can they inform how a lot battery capacity you have got left, however they also can monitor real-time current draw, how a lot energy has been consumed, and the way a lot current stepping into to the battery throughout charging.

Performing this mod requires both patience and high high quality electrical connections. These type of battery monitors use what's called a shunt, which is a high-precision resistor that goes in between the negative battery cable from the battery bank and the battery bank terminal, such that all the present going into the battery bank (charging) and out (discharging) must pass by way of the shunt. The current difference between the shunt terminals is measured and sent to the monitor for display. It is important that all connections are properly made to make sure accurate readings. It should be noted that the shunt, wiring, connectors, and mounting boxes are all sold separately so plan on purchasing these things in addition to the monitor itself.

Mounting options for most monitors embody box mount and surface mount. Surface mounting offers a clear and finished look. Just be certain you've sufficient house behind the mounting surface to accommodate the monitor circuitry and connections. Follow the directions provided with the monitor as they often come with many diagrams and examples, especially the TriMetric brand.

After you've got installed the monitor, the fun begins. There is a bit of tweaking to be executed, like programming in your battery bank capability in amp-hours, charging parameters, time-to-discharge sample intervals, and alarms. After a few discharge-charge cycles, chances are you'll discover that it's essential tweak the parameters again to get them just right. However modding your RV is meant to fun, proper?
