Over-load and short circuit protection

Over-load protection: when the current of controller is 1.*5 times of the rated current, the controller works for *0 seconds; 1.5 times of rated current, works for 5 seconds   Short circuit protection: when the current of controller is more than or equal to 3 times of rated current, the protection starts.

Circuit protection

Over-charge, over-discharge, short circuit and over-load protection

All the protections are harmless to any parts and fuse of controller

Anti- connection-reverse protection for solar battery and storage battery.
