use application. Using appropriate external lightning protection, the effect of a direct lightning strike into a
building can be mitigated in a controlled way, and the lightning current can be discharged into the ground.
Installation of SPDs to protect the inverter against mechanical damage and excessive stress include a surge
arrester in case of a building with external lightning protection system (LPS) when separation distance is kept. To
protect the DC system, surge suppression device (SPD type2) should be fitted at the inverter end of the DC
cabling and at the array located between the inverter and the PV generator, if the voltage protection level (VP) of
the surge arresters is greater than 1100V, an additional SPD type 3 is required for surge protection for electrical
devices.
To protect the AC system, surge suppression devices (SPD type2) should be fitted at the main incoming point of
AC supply (at the consumer’s cutout), located between the inverter and the meter/distribution system; SPD (test
impulse D1) for signal line according to EN 61632-1. All DC cables should be installed to provide as short a run
as possible, and positive and negative cables of the string or main DC supply should be bundled together.
Avoiding the creation of loops in the system. This requirement for short runs and bundling includes any
associated earth bundling conductors. Spark gap devices are not suitable to be used in DC circuits once
conducting; they won’t stop conducting until the voltage across their terminals is typically below 30 volts.
