Surge arrestors for DC PV applications

23 January 2013 Circuit & System Protection

The rapidly growing PV (photovoltaic) industry, now generating at DC voltages of 600 and 1000 V, has placed exceptional demands on the present and previously available surge protection devices intended to protect system components such as inverters, arrays or combiner box components from the effects of lightning induced surges and transients.

Responding to this demand, DEHN has developed and introduced a new product specifically designed to function under the issues associated with these DC voltages. The new DEHNguard M YPV and PV-SCI addresses these issues by incorporating a switched fused circuit in parallel to the MOV discharge circuit, permitting the disconnect to operate arc free.

These SPD products are available for 150 V, 600 V, 1000 V, 1200 V and 1500 V DC applications and are configured in both a ‘Y’ (three-pole) configuration for floating systems, and a two-pole design for grounded systems.
