Surge protective device (SPD)
General
A surge protective device (SPD) protects against temporary overvoltages and dissipates
surge currents (e.g. lightning strike). Building on an overall lightning protection concept,
the SPD helps to protect your PV system components.
For detailed information on the wiring diagram of the surge protective device, see
chapter
Wiring diagram - surge protective device SPD
.
If the surge protective device is triggered, the colour of the indicator changes from green
to red (mechanical display) and the operation LED of the inverter lights up red (see

IMPORTANT!
The inverter also switches off if the 2-pin signal cable of the surge protective device is
interrupted or damaged.
