All connecting cables run inside the mast where they are well protected.
An inverter can be installed on the rotating head or mast if desired. This results
in especially simple and elegant cabling.
The operating voltage of the tracking system is 24 volt. Two batteries 12 V each
are placed in the swivel head on top of the mast. A charger keeps the batteries
constantly fully charged. So each tracker is autonomous and able to move into
storm position even in bad weather conditions or power failure.
