MOV Surge Protection in Photovoltaic Inverters

Photovoltaic power stations in open areas are highly vulnerable to lightning strikes and induced overvoltage. MOV varistors, with their fast response (nanosecond level), large surge current capacity and low clamping voltage, are the preferred choice for lightning protection in PV inverters. Key parameters include varistor voltage, maximum surge current and energy absorption capacity. Lixing Tech varistor series provides sizes from 5mm to 20mm with surge current up to 20kA.
