Operation
WARNING: High power electrical systems pose dangers for independent devices and
meters connected inline. The user should take extra precautions when working with these
devices and take any necessary action to ensure safe use. Shorting a battery with the
meter connected can supply huge currents and have serious consequences including:
explosions, causing fires, damage to equipment, and even personal injury. Make sure your
system does not exceed the values rated on the Renogy 150A Tracer Meter
Once the circuit is complete, the watt meter will turn on, display the default screen, then cycle
through the remaining displays. You can think of the Watt Meter as a set of jumper cables;
essentially a direct connection between same colored SOURCE and LOAD wires. Both the
SOURCE and LOAD leads are electrically “hot” when a battery is connected to wither side.
Current flows from SOURCE to LOAD, assure that all connections are secure to prevent
component damage.
Example #1:
Battery on SOURCE side, Motor Speed Controller (ESC) and motor on LOAD side, With
the ESC on, the watt meter displays the current into the motor, voltage and power at the
battery and the accumulation of Ah and Wh while the motor is running.
Example #2:
Solar Panel on SOURCE side and a battery pack on the LOAD side. The Watt meter
demonstrates the charging current into the battery, the voltage and charging power at
the battery, and the accumulation of the charge in Ah and Wh.
Measurement Screen
Displays Amps, Volts, and Watts. Screens are
updated every 0.4 seconds and they are presented
sequentially every 2 seconds in their appropriate units
(Ah, Wh, Ap, Vm, Wp).
