Proper monitoring of a system should not be overlooked.
Typically we want to know how much power is coming into the
system from its charging sources and the state of charge of the
battery bank at any point in time. A third and equally important
value is how much power is being used by the systems loads.

connection. Small systems usually monitor state of charge, or
battery voltage and possibly incoming amperage. Medium and
larger sized systems typically require a measurement of outgoing
power as well, so one can track production and not over
discharge the battery bank. What is a shunt? A shunt is a device
used to measure large DC current, typically the current flowing
to and from your battery bank. In more detail a shunt is a
precision resistor which produces a very acc
