APOLLO SOLAR CHARGE CONTROLLERS
USE OF SHUNT, SHUNT BOARD, AND ASNET CONNECTIVITY KIT
BASIC OVERVIEW
The basics are simple: The T80 and T100 TurboCharger products include the hardware and
software to measure and display the State of Charge (SOC) of the Battery. The method used
is considerably more practical and accurate than simply measuring battery voltage because
the battery voltage in typical systems will read very high when the battery is being charged
and read very low when the battery is simply being used by the load. (The only way to
depend on the voltage is to disconnect the battery from both loads and charging devices, let it
settle for 20 minutes and then take accurate readings and adjust for temperature.) Since this
is impractical in real systems, Apollo Solar uses a method which continually measures the
current going into the battery from all charging devices and the current going out of the battery
to all loads.
USE OF THE SHUNT AND SHUNT BOARD
The Charge Controller determines when the battery is completely charged as it goes into Float
mode and resets the SOC accumulator. Then the SHUNT measures the current going out of
or into the battery on a continuous basis. The results are displayed on the LCD of the T80
TurboCharger and on the Remote Display when used. The Shunt is wired in series with the
negative lead of the battery. See diagram below:

APOLLO SOLAR: USE OF SHUNT, SHUNT BOARD, AND ASNET
PARALLEL CHARGE CONTROLLERS
Since all the battery current must pass through a single SHUNT, there will only be one shunt
in any system. When the system uses multiple T80 TurboChargers connected in parallel, the
ASNET Option Cards (T80 Network Option Cards) are used to tie them together. Only ONE
SHUNT with ONE SHUNT Board is used to measure the total accumulated current.
The figure immediately below is a simplified wiring diagram of the CAT 5 (Ethernet type) cable
used to connect the T80 TurboChargers together in parallel using the ASNET Option Cards.
The figure also shows the connection of multiple T80s to a single Shunt.
