• Controller can work continuously at full load within the environment temperature range from -25 to 55 ℃
• 3-Stage intelligent PWM charging ：Bulk, Boost/Equalize, Float
• Support 3 charging options: Sealed, Gel, and Flooded
• LCD display design, dynamically displaying device’s operating data and working condition
• Double USB design, the power supply charge for electronic equipment
• With humanized button settings, operation will be more comfortable and convenient
• Multiple load control modes
• Energy statistics function
• Battery temperature compensation function
• Extensive Electronic protection

Product Features

※ USB output ports provide the power supply of 5VDC/2.4A and have the short circuit protection.

Optional Accessory:
Name: Remote Temperature Sensor
Model: RTS300R47K3.81A
Acquisition of battery temperature for undertaking temperature compensation of control parameters, the standard length of the cable is 3m (length can be customized). The  RTS300R47K3.81A connects to the port ③ on the controller.
NOTE: Unplug the RTS, the temperature of battery will be set to a fixed value 25ºC.

Wiring

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 LCD on. Otherwise please refer to chapter 6.Always connect the battery first, in order to allow the controller to recognize the  system voltage.
3. The battery fuse should be installed as close to battery as possible. The suggested distance is within 150mm.
4. The VS AU series is a positive ground controller. Any positive connection of solar, load or battery can be earth grounded as required.
   NOTE: Please connect the inverter or other load that it has the large start current to the battery rather than to the controller, if the inverter or other load is necessary.

4.3 Load mode setting
Operating Steps:
Under load mode setting interface, press SET button and hold on 5s till the number begin flashing, then press MENU button to set the parameter, press SET button to  confirm. 

NOTE: Please set Light ON/OFF, Test mode and Manual mode via Timer1. Timerwill be disabled and display “2 n”.
4.4 Battery Type
Operating Steps
Under Battery Voltage interface, press SET button and hold on 5s then enter into thinterface of Battery type setting. After choosing the battery type by pressing MENU button, waiting for 5s or pressing SET button again to modify successfully.

Battery Type

NOTE: Please refer to the battery voltage parameters table for the different battery type.

Battery Over Voltage| The battery voltage reaches to the OVD| Stop charging
Battery Over Discharge| The battery voltage reaches to the LVD| Stop discharging
Battery Overheating| Temperature sensor is higher than 65t| Output is OFF
Temperature sensor is less than 55t| Output is ON
Controller Overheating| Temperature sensor is higher than 85t| Output is OFF

Restart the controller or wait for one
(night time>3 hours).
Damaged RTS| The RTS is short-circuited or damaged| Charging or
discharging at 25t

Troubleshooting

Wire connection is
correct, LCD not
display| 1)Battery voltage is lower than 9V
2)PV voltage is less than battery voltage| 1)Please check the voltage of battery. At least 9V voltage to activate the controller
2) Check the PV input voltage which should be higher than battery’s
Interface blink| Battery over voltage| Check if the battery voltage is higher than OVD point  (over voltage disconnect voltage), and  disconnect the PV.
Interface blink| Battery over discharged| When the battery voltage is restored to or above LVR point (low voltage reconnect voltage), the load  will recover
Interface blink| Battery Overheating| The controller will automatically turn the system off. But while the temperature decline to be below 50 QC, the controller will resume.
Interface blink| Over load or Short circuit| Please reduce the number of electric equipments or  check carefully loads connection.

Disclaimer

This warranty does not apply under the following conditions:

1. Damage from improper use or use in an unsuitable environment.
2. PV or load current, voltage or power exceeding the rated value of controller.
3. The controller is working temperature exceed the limit working environment temperature.
4. User disassembly or attempted repair the controller without permission.
5. The controller is damaged due to natural elements such as lighting.
6. The controller is damaged during transportation and shipment.
