Surge protection for two parallel PV strings


Base element for PV arresters  

Base element to accept protective plugs for PV applications

The new base element for surge arresters is designed for isolated and grounded DC voltage systems up to 1000 V DC.

It simultaneously protects two MPP trackers of an inverter via separate plus inputs and one common minus input. This thereby enables a space-saving and low-cost installation. Depending on the application, the base element is fitted with type 1/2 or just type 2 protective plugs. Thanks to the modular design, the only item to be considered during the system planning is the unassembled base element. Assembly with corresponding protective plugs can be performed later in the system.
