Meaning of Protection Function
1.PV Reverse Polarity Protection Ifthe solar panel reverse connection, the controller will not destroy,corrected theconnection the controller willbe normally working.-澳门新葡京娱乐556677pj.com
2.PV ShortCircuit Protection Whenthe solar panels have short circuit or reverse connection, the controller willbe off the charging immediately, after clearing of the short circuit,the chargingwill be automatically continue.
3.ThunderProtection Thisproduct could only protect small lightning induction, we suggest to use lightningrod at frequency area.
4.BatteryOver Charge Protection itcan protect the battery from over charge,when battery over chargefunction isworking ,controller will stop charging and can only discharge to the load
5.BatteryOver Discharge Protection itcan protect the battery from over-discharge,when battery over discharge protectionis working,controller will stop discharging to the load ,andcan onlycharge to the battery by solar panel.when charging the battery to LVR voltagepoint,the controller will restart to discharge the load automatically.
6.BatteryReverse Polarity Protection Ifthe batter reverse connection, the controller will not destroy, corrected theconnection the controller will be normally working.
7.BatteryOver Voltage Protection Whenthe voltage of battery was more than 16.5V, the controllerwill be autoclosed charging and output in order to destroy the battery and loads-4996c.com
8.LoadOverload Protection Ifthe current of load is more than 1.5 times rated current of controller, thecontroller will be cut off the output after 30s and lock. Usershave to decreaseloads and press“”unlock, or 30s later thecontroller will auto restart unlock.
9.LoadShort-Circuit Protection Whenthe load have short circuit, the controller will be cut off immediately and lock.Users have to clearing the short circuit and press“→”unlock, or 30slater the controller will auto restart unlock.
10.Reverse BatteryCurrent Flow Protection At Night Duringnighttime when voltage of battery is more than that of solar panels. currentcould start flowing from battery to panels,this could be veryharmful forsolar panel.ldsolar's controller ensures that the current always flowfrom panelto batteries,and never in the reverse direction.
