Method for monitoring service life of intermediate circuit capacitor of electrical system e.g. photovoltaic system, involves outputting alarm signal, if actual values for previously consumed service life exceed threshold limit

摘要

The method involves determining the actual values for previously consumed service life. The actual values are compared with the predetermined threshold limit. An alarm signal is output, if the determined actual values exceed the predetermined threshold limit. Independent claims are included for the following: (1) electrical system; and (2) control unit for electrical system.
