Surge Protection Device for Solar Application
The solar surge protection device is in a high-impedance state and has no impact on the solar PV system at typical operating voltages. When a transient voltage occurs on the circuit, the SPD moves into a state of conduction (or low impedance) and diverts the surge current back to its source or ground.
