6) After a delay of 5-15minutes, the controller should be charging the battery. This can be
verified by measuring the voltage drop between the PV+ terminal and the Battery+ terminal.
If it is zero (Or less than .5Vdc) the controller is charging the battery in Bulk Charge mode.
If you measure a DC voltage, switch your meter to AC voltage and see if an AC voltage is
present. If an AC voltage is present, the SunLight is in the PWM mode and regulating the
battery voltage. If your meter has frequency and duty cycle measurement capabilities, you
can measure the PWM frequency (300Hz +/- 30Hz) and the duty cycle with the common
(black) lead on the PV(+) and Voltage (red) lead on the Battery(+) terminal.
7) After you have verified the controller is charging the battery, disconnect the PV panel (or
Power supply) from the controller terminal. After another wait of 5-15 minutes, your light
should have turned on. If you are using a power supply, you must physically disconnect the
wires from the Solar input terminals. The load switch should be in any position but the “Off”
position (position 0). Do not press the test button – this will disrupt the test you are
performing.
8) To verify the dawn shut off mode, reconnect the PV panel (or power supply) and wait the
delay period for the light to shut off. The way the software is written, the controller will
always shut the load off when dawn is detected whether the controller is in dusk to dawn
mode or any other mode.
