Hello everyone,
I m new to the forum, currently working with solar photovoltaic energy projection and instalation.
The protection for a PV On Grid System (according to almost all material I ve read) consists of:
AC Side:
Circuit Breakers (general system protection - cables, equipments, etc)
Surge Protection Devices (protection for enviromental discharges and grid voltage jumps)
Residual Differential Circuit Breaker (to make sure no current is leaking to earth)
DC Side:
Surge Protection Devices per Array (protection for enviromental discharges and grid voltage jumps)
Disconnect Switch (For maintanance and emergencies)
gPV Fuses strictly necessary when there are more than two strings (according to IEC 60364)
My question is why are fuses not necessary for one or two strings? What exactly are the fuses protecting and why?
I would appreciate a detailed answer if possible and/or material where I can find these answers.
Thank you very much!
