Warning and Safety Instructions
Do not drive over the blanket, leave in wet environments - such as rain or sea water,
or unattended where wind and theft may occur. If wind is likely to be an issue, use
the supplied holes around the edge to tie down or peg the blanket to a secure spot.
1. Risk of explosive gases: Working in the vicinity of a lead-acid battery is dangerous.
Batteries generate explosive gases during normal operation. For this reason, it is of
utmost importance that you follow the instructions each time you use the solar panel
charger.
2. Solar panel charger should not be used by persons with reduced physical, sensory
or mental capabilities unless they are supervised by a person responsible for their
safety.
3. Do not charge non-rechargeable batteries by the solar panel charger. It can
damage the regulator or solar panel charger or create harm for the operator. Only
use the solar panel charger for charging standard lead-acid, lithium-polymer, Li-Fe,
Gel and AGM type 12V batteries .
4. Never smoke or allow a spark or flame in vicinity of battery or engine. This may
cause the battery to explode.
5. Please keep the junction box out of water, if there is some water in the junction
box, please make sure it’s dry before using. Always clean the blanket after use to
keep cells efficient and at their maximum.

How to connect the blanket to your devices
The 120W Baintech solar blanket offers a simple plug and play solution. The blanket
comes with a PWM Solar Controller. The Solar Controller is normally used when there
is no internal controller in your equipment. ( ie: when you want to charge your car
battery, or a secondary battery in a trailer.)
OUTPUT
Connect the Anderson connector with solar charger controller and then connect the
Alligator clamps to your batteries. Always connect the battery you are wanting to charge
FIRST to the Solar Controller before connecting the Solar Blanket. The reason is the
Controller’s AUTO SENSING needs to know what voltage it has to be set at, before the
Controller can operate. The Controller can operate either at 12 or 24 volts Dc.
USING WITH THE BAINTECH POWERTOP
The grey Anderson connector on the Solar Controller is plugged into the Powertop’s
grey Anderson socket or the battery you are intending to charge. The red Anderson
socket is plugged into the cable from the blanket with the same. Plugging the grey
connector in first, allows the auto-select function to kick in and determined if the battery
is 12 or 24 volts before the blanket is connected.

Baintech Watt Meter
Take the guesswork out of how
much power your solar panels are
generating. The Baintech Watt
meter once connected will give
you real time information on:
• Current (Amps/A)
• Voltage (Volts/V)
• Power (Watts/W)

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

②MENU Button ⑥Load Terminals
③RTS Port ⑦SET Button
④PV Terminals ⑧USB Output Ports※
※USB output ports provide the power supply of 5VDC/2.4A and have the short
circuit protection.
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 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.
