Problems
Causes
Solutions
The light remains switched
on during the day
Wrong connection of the PV
Check that the solar module is correctly connected
to the Power 365 battery system unit.
Defect of the solar module
Verify open circuit voltage on the cable towards the
module. You should measure a voltage between 30
and 40 V. If not, the module is damaged.
The light doesn’t work
Open circuit voltage during the
night is higher than detection
threshold for day/night
detection
Check that the solar module doesn’t catch stray
light from the surrounding.
The light doesn’t work
during installation test
Bad cables connection
Check that all connectors are connected and
correctly locked onto the Power 365 battery system
unit.
If the installation happens too
late in the evening, the system
unit doesn’t detect the solar
module and the system stays in
low-power transport mode.
Wait until next day so that the output voltage of the
solar module is high enough.
The light doesn’t work after
it has been working for
several days
Batteries are discharged
Check the connections of the solar module.
Check that there is no shadow on the solar module.
Check tilt angle and orientation of the solar module.
Wait some days if it is winter, if not call FONROCHE
Lighting for further actions.
