1. Safety Information
• Read all of the instructions in the manual before installation.
• DO NOT disassemble or attempt to repair the controller.
• Install external fuse or breaker as required.
• Do disconnect the solar module and fuse/ breakers near to battery before installing
or moving the controller.
• Power connections must remain tight to avoid excessive heating from a loose connection.
• Only charge batteries that comply with the parameters of controller.
• Battery connection may be wired to one battery or a bank of batteries.
• Risk of electric shock, the PV and load can produce high voltages when the controller
is working.
2. Overview
The Polaroid Solar Charge Controller is a PWM charge controller that adopts the most
advanced digital technique. It’s an easy operation and cost ef cient controller featured as:
• 3-Stage intelligent PWM charging: Bulk, Boost/Equalize, Float
• Support 3 charging options: Sealed, Gel, and Flooded
• Battery status LED indicator can indicates battery situation
• Battery temperature compensation function
• With humanized settings, operation will be more comfortable and convenient
• The USB will provide power supply that can charge for electronic equipment
• Battery type and load output can be set via button
• Extensive Electronic protection

4. Wiring
Connect the system in the order of  battery  load PV array and disconnect the
system in the reverse order (see  gure 2).
NOTE: While wiring the controller do not close the circuit breaker or fuse and
make sure that the leads of „+“ and „-“ poles are connected correctly.
NOTE: A fuse which current is 1.25 to 2 times the rated current of the controller
must be installed on the battery side with a distance from the battery not greater
than 150 mm.
NOTE: If an inverter is to be connected to the system, connect the inverter directly
to the battery, not to the load side of the controller.

6. Setting operation
1) Load ON/OFF Setting
When the controller is powered on, press the button to control the load output.
2) Battery Type Setting
Operation:
Step 1: Enter setting mode by pressing button for 5s until the battery status LEDs are
 ashing.
Step 2: Select the desired mode by pressing button.
Step 3: The mode will be saved automatically without any operation for 5 seconds and
LED will stop  ashing.
