PV System: how to ensure safety during normal operation

Two particular characteristics of PV generators are their DC voltage levels and the fact they cannot be shut off as long as PV modules are exposed to the sun. The short-circuit current produced by the PV module is too low to trigger the power supply''s automatic disconnect. The most frequently used protective measures do not therefore apply to PV systems.
