1.PV Reverse Polarity Protection
If the solar panel reverse connection, the controller will not destroy,corrected the connection the controller will be normally working.
2.PV Short Circuit Protection
When the solar panels have short circuit or reverse connection, the controller will be off the charging immediately, after clearing of the short circuit,the charging will be automatically continue.
This product could only protect small lightning induction, we suggest to use lightning rod at frequency area.
4.Battery Over Charge Protection
it can protect the battery from over charge,when battery over charge function is working ,controller will stop charging and can only discharge to the load
5.Battery Over Discharge Protection
it can protect the battery from over-discharge,when battery over discharge protection is working,controller will stop discharging to the load ,and can only charge to the battery by solar panel.when charging the battery to LVR voltage point,the controller will restart to discharge the load automatically.
6.Battery Reverse Polarity Protection
If the batter reverse connection, the controller will not destroy, corrected theconnection the controller will be normally working.
7.Battery Over Voltage Protection
When the voltage of battery was more than 16.5V, the controller will be auto closed charging and output in order to destroy the battery and loads
8.Load Overload Protection
If the current of load is more than 1.5 times rated current of controller, the controller will be cut off the output after 30s and lock. Users have to decrease loads and press“”unlock, or 30s later the controller will auto restart unlock.
When the load have short circuit, the controller will be cut off immediately and lock.Users have to clearing the short circuit and press“→”unlock, or 30s later the controller will auto restart unlock.
10.Reverse BatteryCurrent Flow Protection At Night
During night time when voltage of battery is more than that of solar panels. current could start flowing from battery to panels,this could be very harmful for solar panel. ldsolar’s controller ensures that the current always flow from panel to batteries,and never in the reverse direction
