6. Status LED and troubleshooting

LED DISPLAY OPERATION/CHARGING
(LED green)
2 SEC. BETWEEN FLASHES
Standby: The controller is ready for charg-
ing. Charging starts as soon as there
is enough sunlight.
FAST AND SHORT FLASHING
Charging runs at low current
(input current < ~ 3.5 A)
LONGER FLASHING
Charging runs at high current
(input current > ~ 3.5 A)
LONG THEN SHORT FLASHING
The charge controller is being operated
outside the permissible range and the input
current is limited. Check whether the nomi-
nalvalues for the solar module correspond
to the permissible input values for the
controller.
LED LIGHTS UP CONTINUOUSLY
Battery is completely charged.

Power 48-5000
LED ERROR DISPLAY
(LED red)
2 FLASHES, THEN PAUSE
Overheating: The internal temperature of
the controller is too high.
3 FLASHES, THEN PAUSE OVERLOAD
Controller restarts automatically. If the error
persists, check the module specification
and installation.
4 FLASHES, THEN PAUSE
The controller cannot start the charging
process as the battery voltage is too low.
Charge the battery in another way before
using the controller.
5 FLASHES, THEN PAUSE
Battery voltage too high: This error can
occur, amongst other things, as a result of
a disconnected battery or a defective fuse.
2 × LONG FLASHES, FOLLOWED BY
FREQUENT SHORT FLASHES
Internal error: Contact Torqeedo Service.
If the LED on the controller does not light up when the battery is connected or if
the controller does not charge even though there is sufficient sunlight, the internal fuse
may be defective. The most common reasons for this are:
• Controller is incorrectly connected to the battery
• The solar module input has short circuited. These may cause further internal damage
to the controller.
If the Power 48-5000 cannot be switched on when the charge controller is connected
and there is strong sunlight, there may be overvoltage. In this case, please check the
solar module specifications.
The same applies if the error message 'Overvoltage during charging' is displayed in
the above-mentioned conditions.

7. Monitoring and maintenance

The solar charge controller does not require any maintenance. Nevertheless, the charge
controller and the cables should be checked regularly for external damage.
Use only a soft cloth and mild detergents that are compatible with plastic materials
(e.g. washing-up liquid) to clean the product. Do not use any chemicals or solvents.

7.1 Replacing the fuse

The fuse is located in the fuse holder on the back of the unit. To replace it, open the fuse
holder (2), remove the fuse and replace it with a new ATO
