Lightning is the number one cause of catastrophic failures in solar electric systems and components. The first major reason is that many PV systems are poorly grounded and poorly protected. For PV systems tied to a local power grid, the exposure also includes surges coming from the power grid and the possible differences in the ground potential of the ac power system and that of the dc array system.

The solar PV arrays, with its metallic frame and mounted in the open or on roof tops, act as a very good lightning rod. For this reason, it is prudent to invest in surge protection to eliminate these potential threats and thus maximize the systems life expectancy. The cost for a comprehensive surge protection system is less than 1% of the total system expenditure.

AC DC MOS Protectors offer reliable and cost effective surge protection for PV systems that will keep all your equipment operating as expected.
