When the voltage of battery was reach to LVD (Low Voltage Disconnection) point, the
controller will be auto closed the output in order to avoid over-discharge the battery.
Overload Protection
If the current of load is more than 1.1times rated current of controller, the controller
will be cut off the output after 60s and lock. Users have to decrease loads and press
"→"unlock, or 30s later the controller will auto restart unlock.
Load Short Circuit Protection
When the current of load more than 2times of rated current, the controller will be
confirm short circuit, the controller will be auto cut off the output and lock. Users
have to clearing the short circuit and press"→"unlock, or 30s later the controller will
auto restart unlock
