Overvoltage protection devices

Overvoltage protection devices protect sensitive equipment from
voltage surges.
PLATINUM H inverters are equipped with temperature-protected
metal oxide varistors (TMOV) on both the DC and the AC side which
conduct excessive current from voltage surges to the earth.
For PV plants mounted in open or exposed environments:
 Take additional protective measures on both the DC and the AC
side to prevent these conductors from acting as lightning rods.
If conductors are exposed to transients, these conductors limit the
effectiveness of surge arresters.
To keep surge arresters effective:
 Install one or more surge arresters in systems with long
conductors.
