eLine Technology SOLAR-Charge Controller - Manual (Page 4)

Renogy Charge Controller Model No. PWM10CC 4
2. Charging LED indicator is blinking
a. Check the operating conditions to confirm that the voltage is higher than
the specifications. Consider the temperature compensation of the charge
controller’s PWM set point. For example, at 0°C the charge controller will
regulate at about 15 volts.
b. Check all wire connections in the system to ensure they are in the correct
location. Check for loose wires.
3. Red load LED indicator is blinking or flashing (load not operating properly)
a. Check the load to make sure it is on and make sure the fuses are not
blown.
b. Check connections to the load, other controllers, and battery. Make sure
the voltage drops in the system wires are not exceeded.
c. If the LED indicator is blinking and there is no output, check the load for
short-circuit. In case of short-circuit, disconnect the load and press the
SET button, and wait for approximately 30 seconds for the charge
controller to resume working again.
d. If the LED indicator is still flashing and there is no output, check the load
to make sure the load is not over the rated power. Reduce the load and
press the SET button. Then wait for approximately 30 seconds for the
charge controller to resume working again.
Inspection and Maintenance
It is highly recommended that each user inspect the charge controller at least once per
year to ensure longevity and optimal performance. Please follow this procedure:
1. Confirm that the correct battery type has been used.
2. Confirm that the current levels of the solar array and load do not exceed the
controller ratings.
3. Inspect for loose, broken, or burnt wire connections and replace them if needed.
Make sure all terminals are tightened.
4. Press the SET button until number 16 is displayed to verify the lights are working
properly.
5. Inspect for dirt, insects, and corrosion on the charge controller.
6. Check to make sure there is still enough space around the charge controller for
maximum airflow.
7. Check to make sure the charge controller functions and LED indicators are
working properly.
8. Make sure the PV array is clean and remove any debris.
9. Make sure all of the railings and PV bolts are tightened.
