This connector allows the panels to be directly connected to the battery. Use of this connector should be
done for very limited amounts of time due to lack of protection form charge controller. Risk of
overcharging the battery is great.
GENERAL TESTING PROTOCOL
Always test outdoors under optimal sunlight
Test Solar Panels for Voltage
Connect Voltmeter to each individual panel separately and observe Open Voltage. Open Voltage can range from
16 Volts to 24 Volts.
Test Connection to Charge Controller for Voltage.
Reconnect solar panels, and connect to charge controller as per instructions. Measure the Open Circuit Voltage at
the battery side of the charge controller. Open circuit voltage should read 5-10% lower than without charge
controller. Open circuit measurement will read between 15 and 23.5 volts.
Connect charge controller to battery
First, disconnect solar panels and connect charge controller to battery. Always connect charge controller to battery
first and remove last. Observe polarity – positive to positive and negative to negative.
Reconnect Solar Panels to Charge Controller
If battery voltage is 14.2 or higher, the GREEN light should be on. If battery voltage is between 13 and 14.2, the
YELLOW LED should be on. If battery voltage is 13 or lower, the YELLOW LED should be on.
If all testing results are within the above indicated ranges, solar system is in acceptable range. If Voltage readings
indicate lower ranges, repeat above connections and retest. Finally, it is common to have 12V Battery issues such
as dead cells or non-rechargeable battery problems.
FAQ
What type of batteries does this panel charge?
All rechargeable 12V batteries such as those used in Cars, Boats, RV’s, Motorcycles and PWC’s.
Can I use these solar panels outdoors?
Yes, these solar panels are weatherproof. The weatherproofing includes UV protection and protects from
weather effects of -35°F-175°F (-37°C - 79°C).
Can I overcharge my battery?
Yes, a Sunforce Solar Charge Controller must be used to prevent battery from overcharging..
When will the Charged Indication light (green) light up?
The charged indication green light will light up when the battery voltage reaches 14.2 Volts and the charge
controller will prevent the solar panels from overcharging the battery. It is normal for the charge controller LED to
light on and off as the battery voltage cuts in and out.
