Solar Surge & EMP Protection

A solar array is a large outdoor conductor wired directly into expensive power electronics. Surge and lightning protection is the cheapest insurance in the entire system — a hundred-dollar arrestor standing between a nearby strike and a ten-thousand-dollar inverter.

How to Choose

Protect at every voltage boundary. DC arrestors go on the PV side matched to your string voltage — 300V, 600V and higher ranges are all common. AC protection goes at the service entrance. EMP-rated devices add protection against electromagnetic pulse and coronal mass ejection events, which matters more to off-grid and preparedness builds than to grid-tied ones.

Key Specifications Explained

  • DC voltage rating: 300V, 420V, 600V and dual-channel options — match to string Voc
  • AC protection: 120/240V service entrance devices
  • Response time: Sub-nanosecond on EMP-rated units
  • Mounting: DIN rail, panel mount and inline
  • Coverage: Single or dual DC channels for multi-string arrays

Brands We Carry

EMP Shield, MidNite Solar, Satic Shield and IMO Solar.

Frequently Asked Questions

Do I need both AC and DC protection?

Yes. They protect different halves of the system, and a surge entering through the grid connection is not stopped by a DC arrestor.

Where does a DC arrestor install?

At the combiner box or as close to the inverter DC input as practical. Shorter leads mean better clamping.

Is EMP protection the same as surge protection?

No. EMP devices respond far faster and to a different threat profile. Many customers install both.
