Description
Troubleshoot
Charging LED off during
daylight.
Ensure that the PV wires are correctly and tightly secured inside
the charge controller PV terminals. Use a multi-meter to make
sure the poles are correctly connected to the charge controller.
Battery LED orange (solid)
Use a multi-meter to check the battery voltage to confirm reading.
NEVER disconnect battery without disconnecting the solar
panels first. Turn off all loads connected to the battery (if
applicable) and let the battery charge.
Battery LED orange
(blinking)
The charge controller is operating above the maximum
temperature range. Change the location of the charge controller
to a cooler environment. Follow proper installation procedures to
not damage the system.
Battery LED is green and
blinking fast. LCD is
displaying “OVD”
Battery voltage may be larger than over voltage disconnect
voltage. Use a multi-meter to check the battery voltage and
disconnect the PV modules for a more accurate reading.
Fault LED is blinking red
and LCD displays “Over
Volt”
The solar input may be too high. Use a multi-meter to determine
whether the solar panels are sized appropriately to the controller
and battery bank. The charge controller will pause all activity and
resume work activity once it detects a proper voltage range.
Users cannot connect RS-
