Battery Voltage Sense - SCC MPPT 3KW User Manual

The RTS cable may be pulled through conduit along with the power wires. Tighten the
connector screws with 5 in-lb (0.56 Nm) torque.
NOTE: The RTS is optional package. Please check local dealer for the details.
CAUTION: The controller will not activate temperature compensate charging function
if the RTS is not used.
CAUTION: Equipment Damage
Never place the temperature sensor inside a battery cell. Both the RTS and the battery
will be damaged.
NOTE: The RTS cable may be shortened if the full length is not needed.

3.7 Battery Voltage Sense

The voltage at the battery connection on the controller may differ slightly from the
voltage directly at the battery bank terminals due to connection and cable resistance.
The Battery Voltage Sense connection enables the controller to measure the battery
terminal voltage precisely with small gauge wires that carry very little current, and thus
have no voltage drop. Both battery voltage sense wires are connected to the 2-pole
terminal inside of wiring box (see figure as below).
Be careful to connect the battery positive (+) terminal to the voltage sense positive (+)
terminal and battery negative (-) terminal to the voltage sense negative terminal (-).
No damage will occur if the polarity is reversed, but the controller cannot read a
reversed sense voltage.
