Combined Type 1 and 2 tested protector (to BS EN 61643) for a Photovoltaic PV solar panel system that is on a building where a structural Lightning Protection System (LPS) is employed, for equipotential bonding.

For use at boundaries up to LPZ 0A to protect against flashover (on the DC side of the DC-AC inverter) through to LPZ 2 to protect the PV system from damage.

Features and Benefits

  Enhanced protection (to BS EN 62305) offering low let-through voltage further minimizing the risk of flashover creating dangerous sparking or electric shock
  Repeated protection in lightning intense environments
  The varistor based design eliminates the high follow current (If) associated with spark gap based surge protection
  Compact, space saving design
  Indicator shows when the protector requires replacement
  Remote signal contact can indicate the protectors’ status through interfacing with a building management system

Application

Use on the DC side of the DC-AC inverter for protection against partial direct or indirect lightning strikes. ESP Type 1 AC mains protectors (e.g. ESP 415/III/TNS) are further required at the AC side of the DC-AC inverter
