Windy Nation Solar Panel Charge Controller - Manual (Page 8)

CHC-1224-xx User Manual
Revision 2.0
Note: The output will shut off once there is an overload or short circuit. Disconnect all of the equipment and then
wait a few seconds before reconnecting everything. Press the Power/Mode button and the controller will resume
working after approximately 10 seconds, or in some instances, it may take a few moments longer.
3.2.1 Charge LED
When the connected solar panel is exposed to sunlight, the Charge LED will be green, indicating that the system
is charging normally. In some case, the Charge LED will be green during non-sunlight hours. This because the
solar panels are picking up ambient light (street lights, moon light, etc).
The Charge LED will flash green when an overcharge condition or an open battery circuit exists.
PWM mode is used during charging. If an over-discharge of the battery has occurred, the charger will switch to
boost voltage for 10 minutes, then will return to direct voltage for at least 10 minutes to activate the battery, and
finally to the float voltage state where it will remain to maintain the best state of the battery. This multistep
charging process will help bring the battery to full charge and maximize life span.
3.2.2 Battery LED
The Battery LED is green when the battery voltage is in normal condition. It will blink green slowly when the
battery finishes its charge.
The LED is yellow when the voltage of the battery is below normal.
When battery voltage goes down continuously into an over-discharge condition, the Battery LED will turn red and
the Load output will switch off.
The system will automatically resume normal operation and switch on the load output and when the battery
voltage recovers to the over-discharge return voltage.
3.2.3 Load LED
The load LED is red/orange when a load output is operating normally.
If the load current is 1.25 times higher than the rated current of the controller for 60 seconds or 1.5 times higher
than the rated current for 5 seconds, then the controller will shut down the output and the Load
LED will blink red/orange slowly to indicate that an overload condition occurred.
To resume normal operation, disconnect the load at fault and press the Power/Mode button. The charge controller
will resume normal operation after 30 seconds.
The Load LED will blink red/orange rapidly to indicate that a short circuit condition occurred. If a load short circuit
occurs, the controller will shut down the output. If this happens, verify load connections. To resume normal
operation, remove the short circuit at the load and press the Power/Mode button. The charge controller will
resume normal operation after 30 seconds.
3.3 S ETTING M ODES
The charge controller has a mode setting function to set specific operation parameters. It is preset to the factory
default of normal control. The load will draw from the battery at all times, and the PV panel will charge the battery
when sunlight is available.
To set modes, press and hold the Power/Mode Button until the number on the LED display begins to flash (~5
seconds). Press the button repeatedly to choose the desired mode number. When the desired number is
selected, stop pressing the button and wait for number to stop flashing, indicating that the setting is completed.
The display will turn off after several seconds. Press the button to check the value.
IMPORTANT: Settings 10 through 17 may appear as a single digit and have a dot (.) after the mode number.
IMPORTANT: The controller requires about 10 minutes of continuous transition values before it starts working
properly. These constraints avoid false transitions due to lighting or shading
