Possible reasons
Solar array
disconnection
Battery voltage higher Check the battery voltage. If voltage levels are high,
than over voltage
disconnect voltage
(OVD)
Battery under voltage
discharged
Over load
Short circuit
Temperature of
controller too high
System voltage error
Wrong battery type
selected using the
reconfigured profile
of the user defined
battery type.
Troubleshooting
Check that solar and battery wire connections are
correct and tight.
disconnect the solar module immediately and
change to a new controller.
Load output is normal. Charging LED indicator will
return to green automatically when fully charged.
The controller cut off the output automatically.
LED indicator will return to green automatically
when not working.
Remove or cut out the additional load and press
the button, the controller will resume after
3 seconds.
Clear short circuit and press the button, the controller
will resume to work after 3 seconds.
When heat sink of the controller exceeds 85°C, the
controller will automatically cut input and output
circuit. When the temperature reaches below 75°C,
the controller will resume operation. Reduce the
environment temperature, the power of solar
module or the power of the load.
Check whether the battery voltage matches the
controller working voltage. Please change to a suitable
battery or reset the working voltage. If there is
nothing abnormal, please press load button to
clear the malfunction.
Correct the right battery type;
Using the configuration of the charging voltage
compensation if choosing the user defined battery
type and ignore the SOC.
