Problem Possible reason Solution
The controller doesn’t startup, the screen is of
f. Battery positive and negative reverse connection. Check the wiring, reconnect properly
.
The controller doesn’t load, the PV voltage is
undetectable.
Reverse connection of the positive and negative
cables of solar panels.
Check the wiring, reconnect properly.
Switching from Standby and continuous mode in
circular manner
.
PV voltage too low
, series panels voltage insuf-
cient.
The Vmpp voltage must be higher than the battery
voltage Vbat. Please review the schematics propo-
sed in this manual.
Cloudy day
, too early in the morning or at dawn. Normal phenomenon.
Incorrect solar panels connection. Based that the PV power supply is enough, please
review the series-parallel schematics proposed
above.
The controller is on, the PV voltage is normal, but
the controller doesn’t charge.
The controller doesn’t recognize the voltage battery
system.
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.
The battery has low energy
, or it is empty for a long
period of time.
The number of solar panels is too low to generate
the required energy.,
Increase the number of solar panels.
The battery capacity is too small to storage the
generated Energy
.
Increase the battery capacity
.
