ViewStar A series solar charge controller
1. Overview
Thank you for selecting the ViewStar A series common positive
controller. The VS-A controller is a PWM charge controller with built in LCD
adopts the most advanced digital technique. The multiple load control modes
can be widely used on solar home system, traffic signal, solar street light, solar garden
lamp, etc. The features are listed below:
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
Multiple load control modes
Battery temperature compensation function
Extensive Electronic protection

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 (4
th
) on the controller.
Note: Unplug the RTS, the temperature of battery will be set to a fixed value 25ºC.
3. 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
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.
distance is within 150mm.
(4) The VS-A series is a positive ground controller. Any positive connection of solar
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
necessary.
