9 Maintaining the Sunny String-Monitor
The String-Monitors are usually installed near the modules in the open air. Depending on the system
size, an increased number of String-Monitors is required which must be taken into account during
maintenance work. In the following, some steps are listed which serve as maintenance instruction.
1. First, check the installation site for accessibility, inflammable materials and safe positioning and
then make sure that the Sunny String-Monitor is attached to a horizontal installation and that a
sufficient sun shading system is available, for example by an installation in the PV field.
2. Check whether the enclosure is damaged and properly sealed.
DANGER!
Death resulting from burning and electric shock upon touching the live
components.
• Only work on the device when it is switched off and voltage-free.
