System protection function description
Controller temperature exceed 90
℃
will close the load and charging efficiency will decrease.
Temperature less than 85
℃
will recover.
Battery temperature exceed 55
℃
will close the load and charging will closed. Temperature less than
55
℃
will recover.

、
Overtemperature protection
Decrease the charging efficiency when PV array charging current more than Rate charging current
and less then 1.25 times of Rate charging current for 60s.
Decrease the charging efficiency when PV array charging current more than 1.25 and less then 1.5
times of Rate charging current for 5s.
Decrease the charging efficiency when PV array charging current more than 1.5 times of Rate
charging current for 1s.

、
Charging protection
The controller will start the over discharge protection and close the load when the battery voltage is
less than over discharge voltage and duration 5s.
The controller will start the over discharge recovery protection when the battery voltage exceed the
over discharge recovery voltage.The next night will remove automatically.

Over discharge protection
Short circuit:
The first time short circuit in one day will recover after 5s later.
The second time will recover after 10s later.
The third time will recover after 15s later.
The forth time will recover after 20s later.
The fifth time or more than five times will recover after 4hours later.

Short circuit protection
Also can recover by long press the key!
Over-load protection:
Close the load when load current more than Rate load current also less than 1.25 times of Rate load
current for 60 seconds;
Close the load when load current more than 1.25 also less than 1.5 times of Rate load current for30
seconds;
Close the load when load current more than 1.5 also less than 3 times of Rate load current for 5 seconds;
