Intelligent photovoltaic panel shutdown with Auto Rapid Shutdown:
Based on the analysis of current and voltage conditions in the string lines and in the individual panels, the SOLARCHECK RSD system shutdown units are able to distinguish between the various operating states. In accordance with the fail-safe principle, any deviation from a normal operating state leads to a shutdown, regardless of whether the inverter is shut down, a string line or panel is defective, etc. The intelligent startup unit automatically puts the system back into operation when a safe and technically faultless system environment is present. SOLARCHECK RSD tracks the operating state of the inverter. The system can therefore easily be manually switched on and off via the inverter, for maintenance purposes, for example. This technology, developed and patented by Phoenix Contact, is more reliable and faster than any human assessment or manual intervention.
