CAUTION: It will not damage the solar modules or charge controller if the polarity
is reversed. However, the unit will not be able to function.
WARNING! Please use the appropriate cables. Please refer to Important Safety
Warnings Section for cable details.
Step 4: Switch on DC breaker or install DC fuse
After completing all wire connections, double check to ensure that the wires are
connected correctly. Switch on the DC breaker or install the DC fuse. Uncover
the solar module. When the voltage of solar module is 5VDC higher than the
battery voltage, the charger will automatically turn on.
NOTE: If the battery is not connected, even though the solar module functional,
the charge controller will not activate.
3. Operation
After all wires are connected, the solar charge controller will automatically turn on.
At this time, the blue LED will light up and LCD display panel will show system
status.
Switch Operation
The switch has three modes during operation:
Activate LCD backlight
Press button for less than 1 second
Select battery type*
When the unit starts to work, press button for 1-3
seconds to select battery type.
DI: vented battery
D2: sealed lead acid battery
D3: Gel battery
D4: NiCd battery
D5: Custom**
Mute
Press button > 3 seconds
Power on
Press button for 1 second to turn on the unit.
*Carefully select battery type. An incorrect selection could damage the battery.
Refer to the charging voltage table in the appendix.
