Operating Instructions
Read the ENTIRE IMpORTANT SAFETy INFORMATION section at the beginning of this manual
including all text under subheadings therein before set up or use of this product.
Note: Performance of the Solar Panels will vary dependent on site location, angle
of the panels in relation to the arc of the sun, and available sunlight.
Recharging a Battery
1. To recharge a 12 volt battery (not included),
while paying attention to the proper polarity
(black (-) is negative and red (+) is positive),
connect the two ring terminals on the Battery
Clamp to the Battery Terminals on the back
of the Charge Controller. See Figure H.
2. Connect the black clamp to the black or negative (-)
terminal on the battery (not included). Finally,
connect the red clamp to the red or positive (+)
terminal on the battery. Avoid accidental contact
of the red and black battery clamps to each other.
3. Turn on the Charge Controller. See the On/Off
switch in Figure H. Initially charge for three days.

For technical questions, please call 1-888-866-5797.
NOTE: The voltage display will have to be turned on
in order to monitor the battery voltage. (Press the
Voltage Meter Switch to turn off the Voltage Meter
when not monitoring the battery voltage since it
consumes energy.) Twelve (12) Volt batteries should
charge to 13 Volts for a full charge. To stop charging
the battery, turn Power Switch to OFF and disconnect
the solar panels from the Charge Controller.
NOTE: The Charge Controller provides "overcharge"
protection. If the battery voltage is higher than 14.5
V, the regulator will shut off charge from solar panel.
4. The Charge Controller provides the
following protection while charging:
a. Over-discharge Protection: When the electricity
level of the battery goes too low (below
11 volts) from product usage, the Charge
Controller will automatically shut off the power
output to prevent damage to the battery. If
this occurs, stop using the battery and charge
it until the Voltage display shows 13 volts.
b. Overcharge Protection: If the electricity level
on the battery goes too high (above 14.5 volts)
the Charge Controller will automatically shut off
power input to prevent damage to the battery.
c. Overload Protection: If the output current
exceeds 4 amps the fuse (see Figure F) will
blow to prevent damage to the controller in
the Charge Controller. If this occurs, have a
qualified service technician replace the fuse.
Note: The On/Off switch of the charge controller
must be in the "On" position to activate the
three protection functions mentioned above.
