Test it out

System Integration
One way to test out a complicated system is to build it on the test bench before installing it. This is a great idea on so many levels. It allows you to get thoroughly familiar with what we are installing, it is so much easier to work on a system sitting on a table, and it allows you to get the bugs out without being on your hands and knees.

Why is my Amp Hour Meter giving strange readings after its winter break?
Posted by Liam Kennedy on 1/21/2019 to
Battery Monitoring
Amp hour meters do a great job at assisting the boat owner with battery management. They provide an accurate reading of voltage and of amps going in and out of the batteries and by keeping track of these readings over time they can provide a reading of "amp hours" or the state of charge of the battery as a percentage. They also often maintain a record of historical data and can use that to figure out battery efficiency.
How big a battery bank do I need?
Posted by Liam Kennedy on 1/18/2019 to
Batteries (Conventional)
For most people to answer to this is "as big as possible". Charlie Wing's book the "Boatowners Illustrated handbook of Wiring" has a very good explanation of how to calculate the capacity you need. The calculations start by working out what your daily load will be both at anchor and while underway.
