The German Supplementary Sheet the light- ning protection standard IEC 62305-3 also requires – to protect the inverter the installation surge pro- tection the side. House with lightning protection system and internal light- ning protection system 3.2.3 Residential and industrial applications Transient surges resulting from lightning strikes and switching operations cause the failure and destruction of electronic devices. TVs, videos and DVD recorders, stereos Telephone systems • Analogue • ISDN NTBA • telephony systems Construction engineering/installations • Heating controls • Solar and photovoltaic systems • Building automation Terminals • Computer • Household appliances, burglar alarm systems, etc. Using surge protection devices reduces downtimes of devices and systems. To prevent loss investments, relevant insurance-related questions need considered. Under VdS Directive 2010, property insurers require systems kWp more be fitted with lightning protection and internal surge voltage protection.2.
