Can you introduce me some protection circuits in solar array ?
Question:
Answer:
Protection on my system consists of switches and fuses, and a continuous ground connection between each module and an earth ground.
One fused switch isolates the modules from the rest of the system. Another isolates the system from the public utility,
A fuse protects the AC circuit feeding the control unit. Another protects internal components.
And,of course, there is the building service entrance switch and fuses.
I migth add ground fault detectors and lightingrods
