5. Protections
•
PV Short Circuit
When PV short circuit occurs, the controller will stop charging. Clear it to resume normal operation.
•
PV Reverse Polarity
Fully protection against PV reverse polarity, correct the wire connection to resume normal operation.
•
Battery Reverse Polarity
Fully protection against battery reverse polarity, correct the wire connection to resume normal operation.
Warning : Shock Hazard!
When the battery is reverse, the load will appear the equal and reverse polarity voltage to battery.
•
Battery over voltage
When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage, the controller will stop
charging the battery to protect the battery from being over charged to break down.
•
Battery over Discharge
When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage, the controller will stop
discharging the battery to protect the battery from being over discharged.
•
Battery Overheating
The controller detect the battery temperature through the external temperature sensor. If the battery temperature exceeds
65
º
C, the controller will automatically start the overheating protection to stop working and recover below 50
º
C.
•
Load Overload
Load will be switched off when 1.05 times rated current overload happens. Controller will automatically attempt
to reconnect load for 5 times. It overload protection still exist after controller
’
s 5 times attempts, user have to
reduce load appliance, then press the SET button or repower the controller or wait for one night-day cycle (night
time>3 hours).
