Why
Have Surge Protection?
Photovoltaic,
wind, and hydroelectric systems usually have long runs of exposed wire that can
pick up surges from lightning, even if the lightning strike is only nearby.
These power surges can damage sensitive electronic components in meters, charge
controllers, and inverters. Surges can also damage telephone, audio, and video
equipment connected to the power system. It is a good idea to install surge
protection on all incoming wires in the system, including incoming
photovoltaic, wind, or hydroelectric power lines; AC generator lines; and
telephone and antenna leads. Proper grounding is absolutely necessary for
lightning protection to be effective. In the event of a direct strike, damage
may occur, even with surge protectors installed. Type 1 heavy duty surge
protectors are recommended when a direct lightning strike is possible on the
installation.
