discharging at the default temperature 25 ºC.
②The port can provide the DC power supply of 5DC/150mA and have the short circuit
function. NOTE: When the RS485 communication port is not working, the
waterproof cap must be installed to prevent water getting in.
4. Wiring
Connection Order
1) Connect components to the charge controller in the sequence as shown above and
pay much attention to the “+” and “-”.Please don’t insert the fuse or turn on the breaker
during the installation. When disconnecting the system, the order will be reserved.
2) After power on the controller, check the battery LED indicator on the controller, it will
be green. If it’s not green, please refer to chapter 9.
3) Connect a fuse in series through battery positive (+) in the circuit and the battery
circuit fuse must be 1.25 to 2 times to the rated current. The installed distance is within
150mm.
Load self-test function
The load is ON when the controller power on 10s. After 10s it will restore to set working
mode.

6.Load Working Mode
1) Manual Mode
2) Light ON/OFF(Default)
3) Light ON+ Timer
4) Real-time Control
Control the load ON/OFF time through setting real-time clock.
5)Lntelligent Power Mode
After the mode of intelligent power reduction is turned on and the capacity of the storage
battery is lower than 50%, the load will make adjustment by automatically reducing the
power in a linear manner according to the capacity of the storage battery, and
meanwhile the load will operate based on the minimum value between the set value and
the value after power reduction. Moreover, the mode of intelligent power reduction will
be exited after charging is started on the next day.
NOTE: In the mode of Light ON/OFF and Light ON/Timer, the Load is
turned on after 10Min. delay.

8. Protection
PV Over Current
The controller will limit battery charging current to the Maximum Battery Current
rating. Therefore an over-sized solar array will not operate at peak power.
PV Short Circuit
When PV short circuit is powered on or PV input is short circuit on low-power, the
controller will stop charging. Clear it to resume normal operation.
WARNING: The controller may be damaged, when PV input is short
circuit on high-power.
PV Reverse Polarity
Fully protection against PV reverse polarity, correct the wire connection to resume
normal operation.
WARNING: Controller will be damaged when the PV array straight
polarity and the actual operation power of the PV array is 1.5 times
greater than the rated charge power!
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 detects the environment temperature through the external temperature
sensor. If the environment temperature exceeds 65 ºC, the controller will automatically
start the overheating protection to stop working, and recover below 55 ºC .
Lithium battery Low Temperature
The temperature sensor is less than the low temperature value, Lithium battery stop
charging/discharging. It is higher than the low temperature value, Lithium battery start
charging/discharging.
Load Overload
If the load current exceeds the maximum load current rating 1.05 times, the controller
will disconnect the load. Overloading must be cleared up through reducing the load
and restarting controller.
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).
Temperature sensor break down
If the temperature sensor short-circuited or damaged, the controller will be charging
or discharging at the default temperature 25 ºC to prevent the battery damaged from
overcharging or over discharged.
High Voltage Transients
The controller is protected against small high voltage transients. In lightning prone
areas, additional external suppression is recommended.

Load Overload①
①Please reduce the number of
electric equipments.
②Restart the controller.
③wait for one night-day cycle (night
time>3 hours).
Load Short Circuit①
①Check carefully loads connection,
clear the fault.
②Restart the controller.
③wait for one night-day cycle (night
time>3 hours).
①When it is overload or short circuit, the load have 5 times auto-recovery output
function, which each times delay respectively 5s, 10s, 15s, 20s, 25s.
11. Disclaimer
This warranty does not apply under the following conditions:
Damage from improper use or use in an unsuitable environment.
PV or load current, voltage or power exceeding the rated value of controller.
