Charge Controller Operation
Please make sure to read charge controller's manual for operation and safety recommendations.
Green LED light: Indicates a fully charged battery*.
Red LED light: Indicates the battery is being charged.
* The age, condition or use of a battery may sometimes affect whether or not the Green LED lights up.
Note: It is normal for both lights to flicker on and off during normal operation. The Battery Charge
Controller should be placed within 5' of the battery in a dry, well-ventilated area. All connections
should be parallel to ensure a 12 Volt system (positive to positive and negative to negative).
Use of included adaptors
12 Volt DC Plug Connector (FIGURE 1, #4)
•
This connector allows panels to be directly connected into a 12 Volt DC Socket. 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.
12 Volt DC Socket Connector (FIGURE 1, #5)
•
This connector allows 12 Volt devices to be connected directly to the panels. Since the panels
have variable voltage, use of this cable is limited. Refer to your 12V device operating
recommendations.
Power Inverter Connector (FIGURE 1, #6)
•
This connector is intended for use with the Power Inverter only.
Battery Clamps Connector (FIGURE 1, #7)
•
This connector allows the panels to be directly connected to a 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
Note: Always test outdoors under optimal sunlight.
The use of a voltmeter of multi-meter is required.
Test Solar Panels for Voltage
Connect Voltmeter to each individual panel separately and observe Open Circuit Voltage. Open Circuit
Voltage can range from 16 Volts to 24 Volts.
Reconnecting Charge Controller and Panels
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 14.2V or higher, the GREEN LED
should be on. If battery voltage is under 14.2V, the YELLOW LED should be on.
* Be aware that not all batteries may reach 14.2V depending on their age, condition or use.
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.
