COMMON FAULT TROUBLESHOOTING
Problem
The controller doesn't startup, the screen is off.
The controller doesn't load, the PV voltage is
undetectable.
Switching from Standby and continuous mode in
circular manner.
The controller is on, the PV voltage is normal, but
the controller doesn't charge.
The battery has low energy, or it is empty for a long
period of time.

Possible reason
Battery positive and negative reverse connection.
Reverse connection of the positive and negative
cables of solar panels.
PV voltage too low, series panels voltage insuffi-
cient.
Cloudy day, too early in the morning or at dawn.
Incorrect solar panels connection.
The controller doesn't recognize the voltage battery
system.
The number of solar panels is too low to generate
the required energy.,
The battery capacity is too small to storage the
generated Energy.

Solution
Check the wiring, reconnect properly.
Check the wiring, reconnect properly.
The Vmpp voltage must be higher than the battery
voltage Vbat. Please review the schematics propo-
sed in this manual.
Normal phenomenon.
Based that the PV power supply is enough, please
review the series-parallel schematics proposed
above.
Check the battery voltage with a clamp, compare
it with the LCD information and and confirm that
ir is within the operation range of the controller.
Increase the number of solar panels.
Increase the battery capacity.
