EPEVER PWM-VS1024AU AU Series Solar Charge Controller

Overview

Thank you for selecting the ViewStar AU series common positive solar charge controller. The VS-AU controller is a PWM charge controller with built in LCD display that adopts the most advanced digital technique. The multiple load control modes enable it can be widely used on solar home system, traffic signal, solar street light, solar garden lamp, etc. The features are listed below:

• Adopt high quality components of ST,IR and Infineon, make sure product using lifespan
• Terminals have UL and VDE certification, the product is more safer and more reliable
• Controller can work continuously at full load within the environmen 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.

2. Accumulative power zero clearing: Under PV power interface, press SET button andhold on 5s then the value blink, press SET button again to clear the value.
3. Setting temperature unit: Under battery temperature interface, press SET button and hold on 5s to switch.

• Fault Indication
  

  Status	Icon	Description
  Battery over discharged		Battery level shows empty, battery frame blink, fault icon blink
  Battery over voltage		Battery level shows full, battery frame blink, fault icon blink
  Battery Overheating		Battery level shows current value, battery frame blink, fault icon blink
  Load failure		Load overload ①,Load short circuit

① When load current reaches1.02-1.05 times 1.05-1.25 times, 1.25-1.35 times and 1.35-1.5 times more than nominal value, controller will automatically turn off loads in 50s, 30s,10s and 2s respectively

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.

	Timer 1		Timer 2

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

Protections

Troubleshooting

Faults	Possible reasons	Troubleshooting
The LCD is off  during daytime when sunshine falls on PV modules properly	P array disconnection	Confirm that PV wire connections are correct and tight
Wire connection is correct, LCD not display	Battery voltage is lower than 9V PV voltage is less than battery voltage	Please check the voltage of battery. At least 9V voltage to activate the controller 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 ºC, 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.
