    For proper operation in a larger solar system, the normal measures of regular system monit- oring are fully sufficient. In particular, tracking the energy obtained via data loggers, the KOSTAL Solar Portal or en- ergy meters will quickly indicate irregularities. Events during operation are also logged.
