6.2 Troubleshooting

Charging LED indicator off during daytime when sunshine falls on solar
modules properly.
Probable Cause
：
Solar modules disconnected.
Solution
：
Confirm that PV and battery wire connections are correct and tight.

Battery LED indicator red flashing, LCD displaying „OVD‟.
Probable Cause
：
Battery voltage larger than over voltage disconnect voltage (OVD).
Solution
：
Check if battery voltage too high, and disconnect solar modules.

Fault LED indicator flashing, LCD displaying „Current Err‟.
Probable Cause
：
Charging current in three paths is unbalanced.
Solution
：
Disconnect solar modules and restart the eTracer; if the fault still exists,
please contact the supplier to make maintenance.

Fault LED indicator flashing, LCD displaying „Over Current‟.
Probable Cause
：
Charging current is much more than the rating.
Solution
：
Please check whether solar modules match with nominal parameter of the
controller. When charging current reaches 1.05~1.2 times of the rating, eTracer will
automatically adjust charging current to the rating or below but not stop; or 1.2 times
much more than nominal value, eTracer will automatically stop charging in 5 seconds.
Controller is automatically circularly activated so as to reconnect charging. Every
restarting is 60 seconds delayed, but no limit on number of times.

Fault LED indicator flashing, LCD displaying „Over Temp‟.
Probable Cause
：
Heat sinks operational temperature is quite high to 85
℃
or above.
Solution
：
The controller will automatically stop working. When the temperature below
75
℃
, the controller will resume to work.
