when the battery voltage is higher than UWRV, the controller will exit the intelligent

power mode.

NOTE：The load is ON when the controller power on 1seconds. After 1

seconds it will restore to set working mode.

NOTE: In the mode of Light ON/OFF and Light ON/Timer, the Load is

turned on after 1Min. delay.

Li-Battery Solar Charge Controller

※Specific instructions refer to the list of accessories and software.

8. Protection

 PV Short Circuit

 If the PV array short circuit, 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.

 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 to break down.

 Battery Overheating

 The controller detect the environment temperature through the external temperature

sensor. If the environment temperature exceeds 65 º C, the controller will

automatically start the overheating protection to stop working, and recover below 50

º C.

 Libattery low temperature★

 The controller detect the environment temperature through the external temperature

sensor. If the temperature sensor is less than the low temperature value, the

controller will automatically stop charging or discharge and recover higher than the

low temperature value.

 Load Short Circuit

 Load will be switched off when load short circuit (≥4 times rated current) happens.

Controller will automatically attempt to reconnect load for 5 times. If short circuit

protection still exist after controller's 5 times attempts, user have to clear short

circuit ,then restart the controller or wait for one night-day cycle (night time>3 hours).

 Controller Overheating

 If the temperature of the controller exceeds 85 º C, the controller will automatically

start the overheating protection, and recover below 75 º C.

 High Voltage Transients

 The controller is protected against small high voltage transients. In lightning prone

areas, additional external suppression is recommended.

★Warning: If selecting a lithium battery, it must be set low temperature

value(LTV) according to the charging/ discharging temperature of lithium

battery; otherwise, the lithium battery will be damaged.
