Renogy Charge Controller Model No. PWM10CC 3
Led Indicator
Icon LED Description
Solar Panel
• Green ON: Solar power is charging the battery
• Green BLIKING: The system is over voltage
Battery
• Green ON: Battery level is in the right range
• Green SLOWLY FLASHING: Battery level is full
• Yellow ON: Battery level is low
• Red ON: Load cut-off
DC Load
• Red ON: The output is on
• Red SLOWLY FLASHING: Overload
(The load amps is 1.25 times of the rated current for 60 seconds or
the load amps is 1.5 times the rated current for 5 seconds)
• Red BLINKING: Load is short-circuit
Table 3. LED indicators
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
SET button and the controller will resume working after approximately 10 seconds, or in
some instances, it may take a few moments longer.
Troubleshooting
What do I do when…
1. Charging LED indicator turns off during the daytime
a. The green LED should be ON during the daytime.
b. Check to make sure the correct battery is being used.
c. Check all wiring connections to make sure they are in their designated
locations and make sure that there are no loose connections.
d. Measure the PV array open-circuit voltage and confirm it is within its
normal limits.
e. Measure the PV voltage and the battery voltage at the controller terminals.
If the voltage at the terminals is within proper specifications, the PV array
is charging the battery properly. If the PV voltage is within specifications to
the open circuit voltage rating of the panels, but the battery voltage is low,
the charge controller may not be charging the battery and it may be
damaged.
