3 Residential and industrial applications
Transient surges resulting from lightning strikes and
switching operations cause the failure and destruction
of electronic devices.g. Under VdS Directive 2010, property
insurers require systems kWp more be
fitted with lightning protection and internal surge
voltage protection. To
prevent loss investments, relevant insurance-related
questions need considered. The German Supplementary Sheet the light-
ning protection standard IEC 62305-3 also requires –
to protect the inverter the installation surge pro-

Surge voltages can lead the failure systems
and hence failure achieve the expected yields. Surge
protection measures should taken for the following
devices and systems:
