Like any electrical installation, the equipment constituting a PV installation (inverters and PV panels) can be subjected to destructive electrical perturbance: transient overvoltages generated by lightning.
CITEL has designed a complete range of Type 1 and Type 2 surge protectors for PV applications that are compliant with the IEC 61643-31 (or EN 50539-11) test standard.
