ViewStar AU series solar charge controller

1. 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 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

Figure 2 Connection diagram

(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

(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.
