Acti 9 iPRD-DC-PV

Acti 9 iPRD-DC-PV Surge Protection Devices Type 2 are meant to protect against the overvoltages coming from the lightning strikes:
- of the PV inverter direct current input
- and of the photovoltaic panels.
Maximum steady state voltage: 800 V DC, 1000 V DC
Maximum discharge current Imax = 40 kA


Surge Protection Devices should be installed in a switchboard inside the building. If the switchboard is located outside, it must be weatherproof.
