  • Page 118: During Operation

    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.

  • Page 119: Maintenance And Cleaning

    Use maintenance lists in which the work undertaken is logged. If no maintenance work is carried out, this will result in an exclusion of warranty (see 'Exclu- sion of warranty' in our service and warranty conditions). © 2022 KOSTAL Solar Electric GmbH...

  • Page 120: Housing Cleaning

    Only clean the housing with a damp cloth. Do not use any harsh cleaning agents. Do not use devices that produce a spray or water jet. In particular, check the condition of the ventilation ducts and the function of the fans. © 2022 KOSTAL Solar Electric GmbH...

  • Page 121: Fan

    Do not use compressed air, vacuum the inverter's ventilation ducts instead. ■ Remove detritus consisting of leaves, dust, insects, etc., especially in the vicinity of the ventilation ducts. ■ For example, use an industrial vacuum cleaner and vacuum the ventilation ducts and immediate surroundings. © 2022 KOSTAL Solar Electric GmbH...
