This unit is supplied for use with the automatic agrometeostation (art. no 16.99). It incorporates a high grade polycrystalline solar cell array (1W), which is capable of powering an meteostation continuously in almost all parts of the globe, except areas towards the poles in winter. The unit gives an output of 12 Volts and plugs into the automatic Agro-Meteostation via its RS232 socket which is used for configuring and reading out the automatic agro-meteostation when the solar energy system is connected. The solar energy system works by charging the batteries that are built into itself when the sun shines, and then using the power stored to supply the automatic agro-meteostation in the dark or on clouded days. It will charge its batteries when the solar energy level is approximately 80 watts/m2 or above. The internal rechargeable batteries of the solar energy system will run an automatic agro-meteostation in total darkness for typically 7 weeks (5 weeks at -20 °C) with most types of automatic agro-meteostations and logging times.
Same system as described before with two high grade polycrystalline solar cell arrays (2 W).
