Lightning Arrestors

Made by Delta

Outdoor electrical systems attract lightning.  Lighting doesn't have to hit your installation, a strike close by can destroy components in a renewable energy system, leading to costly repairs and unpredictable power outages.  Protect your investment from the hazards of nature with a lightning arrestor on the DC and AC circuits of your renewable energy system.

Use a surge arrestor to protect AC and DC circuits of a photovoltaic or wind energy installation from lightning strikes.    Three wires make installation quick and simple, while rugged electronic components can handle an infinite number of "surges" however a heavy or continuous high voltage can burn them out.

In the event of a lightning strike or surge the surge arrestor conducts the charge bleeding it out of the circuit to ground.

PV systems are mounted in locations vulnerable to lightning. The cost of surge protectors are negligible compared to the cost of the equipment being protected.  Consider installing both a DC and an AC surge protector within your system. The DC surge protector can be mounted close to and electrically prior to the solar charge controller.  The AC surge protector can be mounted on the AC load or distribution panel. Both should be connected to the grounded service conductor, or service equipment grounding conductor or a separate grounding conductor.
