Solar Panel - Thies CLIMA DLx-MET Instructions For Use Manual

Additionally a red LED lights up between clamp 67 and 68 for control the 24VAC supply (normally
used for heating of sensors). In case of malfunction check the fuses 230VAC and 24VAC.
Remark for 9.1756.x0.001:
The 26Vac output has no fuse, but a 135°C thermal trip switch which breaks the
primary supply.

Solar panel

Electric Connection:
The connection of the optional solar panel is to be carried out according the wiring plan
(see chap. 7). We recommend to earth the panel for protection against lightning strikes.
The integrated 12V solar regulator generates a temperature-controlled voltage for a
optimum load of the battery. The maximum power of the panel should not exceed 20W,
otherwise the regulator could be damaged. Due to the temperature-controlling the battery
should be always in the case of the datalogger.
Alignment:
•
Direction: Always align the panel pointing to the sun at noon (south on the northern
hemisphere and vice versa) for an optimum performance. If necessary, refer to a compass.
•
Angle: The optimum tilt angle (angle between the horizontal plane and the solar panel, (see
Figure 11) depends on the latitude of the site. If the datalogger is to be used all the year
round, we recommend a tilt angle for optimum winter performance :
Tilt Angle = Latitude + 15° (apply not for Arctic / Antarctic region, maximum tilt angle 90°)
Example: Berlin(Germany) Latitude: 50.3°
•
Nearby obstacles (trees, sensors etc.) should not block the sun at the panel.
Maintenance:
•
Dirt, snow, leaves etc. on the panel reduces the amount of light and decreases the energy
yield. Therefore regularly clean the glass of the panel depending on the vicinity.
