The CHRG screen displays the sum of the internal and exernal
currents. By doing a long push on the CHRG screen you can see
how much each device contributes to the total charge.
The first screen is called CINT and displays the internal charge.
The next screen(s) display any currents reported by external
devices. (For details, see the reference manual)
What is the load current?
The top level LOAD screen displays the load (or discharge)
current. This is the total current used by all loads. A long push
will display the internal load current (LINT) and any external load
currents.
How full is the battery?
The voltage level of your battery is a good measure of how full it
is, and is shown on the top-level “BATV” screen. Alternatively,
SOC in the DATA sub-menu (long-push on DATA, then three
short-pushes) uses amp-hour, voltage & temperature data to
provide an estimate of the state of charge. (Warning: SOC will
be meaningless if the controller is not measuring all the charge
and discharge from the battery. For example, if an inverter
is connected directly to the battery, an external shunt and an
external shunt adaptor is needed so that the controller can
include the inverter current in its calculations. There will also be
errors due to temperature and the age of the battery).
