2. Determine the correct angle of inclination for the solar panel.
The position of the sun above the horizon changes during the seasons. As
a general recommendation, an angle of 50 degrees is optimal for long-term
use in most parts of Europe. Nevertheless, the angle can be adjusted condi-
tional upon the season to optimize the output of the solar panel for recharg-
ing the rechargeable battery (see Fig. below). The steeper the angle of
inclination, the greater the cleaning effect during rain or snow

It may be the case that in winter (except for southern Europe) there are not
enough hours of sunshine to fully charge the rechargeable battery.
3. Regularly remove any deposits and dirt from the solar panel
This includes removing dust leaves and snow, since these can reduce the
performance of the module for recharging the rechargeable battery.
Only check the rechargeable battery indicator in solar operation at dawn
(without sunlight).
WARNING:
Do not leave the switched off device in the sun with a rechargeable
battery and a solar panel for a longer period. Why?
This could damage the rechargeable battery.
4. Energizer Operating Description
Solar operation:
The solar panel produces electricity as soon as it is exposed to usable sunlight. The pasture fencer constantly requires elec-
tricity - by day as well as by night. The electricity generated in this way by the panel is stored in a rechargeable 12V battery,
which means the energizer can operate without sunlight. The solar panel may not always have a sufficiently large output
to fully recharge a rechargeable battery – especially in dark, grey and misty months (e.g. October to
February).
The energizer is operated primarily from the solar panel. If the solar panel does not have sufficient output,
the energizer switches automatically to the connected 12 volt rechargeable battery.
Rechargeable battery indicator:
The rechargeable battery indicator provides information about the rechargeable battery or battery voltage. The solar display
lights up constantly in green when the solar panel charging voltage is greater than the voltage of the rechargeable battery/
battery. Whilst the solar panel charges the 12V rechargeable battery.
