System Status Troubleshooting
Description
Troubleshoot
Battery is low-voltage
Use a multi-meter to verify the rated battery voltage.
Disconnect any loads connected to the battery to allow it to
charge.
Battery is over-voltage
Use a multi-meter to check the voltage of the battery. Make
sure the battery voltage is not exceeding the rated
specification of the charge controller. Disconnect battery.
PV is over-voltage
Use a multi-meter to check the voltage of the panels. Ensure
that they meet the specification of the controller to not
exceed 25 VDC.
PV terminal low output
The PV output is typically lower in the early mornings and in
the late afternoons. This should not require troubleshooting
unless a solar panel is defective.
Battery is over-heating
When heat is exceeding the specification of the controller, it
will automatically shut down. The controller will resume to
operate once it interprets a change in temperature.
Other Considerations
Charge controller does
not charge during
daytime when the sun
is shining on the solar
panels.
Confirm that there is a tight and correct connection from the
battery bank to the charge controller and the solar panels to
the charge controller. Use a multi-meter to check if the
polarity of the solar modules have been reversed on the
charge controller’s solar terminals.
No LED indicator when
battery is connected to
the charge controller
The battery voltage may be less than 9V. A minimum of 9V
is required to power on the controller.
Battery LED light does
not flash when holding
for 7 seconds.
The battery selection LED must be enabled. Disconnect the
battery from the controller, then connect the battery to the
controller to reset it. Then hold the gray button for 7
seconds, release the button, and then immediately press the
gray button one more time to select a battery type.
