Product Description
The Renogy Solar Suitcases combine highly efficient Renogy Solar Panels and a fully adjustable 10
Amp PWM Fully Adjustable Solar Charge Controller with LCD Screen to create an easy-to-use,
‘plug and play’system.
This system is specifically designed for mobile off-grid applications, where space and weight
limitations are abundant. The Solar Suitcase 100W supports 12V deep cycle battery varieties such
as sealed lead acid, gel, and flooded. With built-in tilting stands, these panels can be adjusted at
different angles to maximize the power output throughout the seasons.
The alligator clips included in this package make it easy to connect the panel to a battery in
seconds. If one ever needs to connect a battery with a different type of end terminal, the alligator
clips are attached via MC4 Connectors.
PWM Technology
The built-in charge controller is based on advanced Pulse Width Modulation (PWM) charging
technology. With a charging range of 0-100%, it can charge a battery quickly and safely under any
condition of the solar photovoltaic system.
When charging, the controller utilizes automatic duty cycle conversion, creating pulses of current
to charge the battery. Intermissions make the oxygen and hydrogen generated by chemical
reactions combine again and become absorbed. This process can naturally eliminate both
concentration polarization and ohm polarization, and can also reduce the internal pressure of the
battery; thus, the battery will absorb more power. Pulse current charging mode allows the battery
more time to react, which reduces the gassing volume and makes the battery improve the
acceptance rate of the charging current.

Suitcase 100W, please visit our Guides and Downloads webpage, and download the separate

Installation
1. Unclip the two latches on the side of the unit and unfold the two panels outward.
Extend the stands to support the solar panels.
2. The controller is mounted on metal plate. The plate is attached to the back of the panel
with Velcro. The hinges attached to the metal plate allow the user to swivel the charge
controller to get a better look at the LCD display. The Velcro allows the re-attachment of
the charge controller back under the panel.

3. Fully extend battery leads. Connect the red alligator clip to the positive (+) battery
terminal and the black alligator clip to the negative (-) battery terminal on a 12V battery.
Ensure that the connections are secure.
Note: The kit should be connected to a battery generating at least 9V to start the charge controller. If the
12V battery is fully discharged, charge it for a short period of time by other means to reach 9V.
4. When you connect the kit to the battery, the charge controller will display a boot up
message as follows:

5. Adjusting Battery Size and Type: Press to enter to the options, press or
to navigate to the menu options.
When the inverse cursor rests on 5. Rated Value, press to enter into the nominal
parameter interface. Once again, press or to move between the adjustable
parameters. Pressing will move the inverse cursor to the right. While pressing
will move it to the left. If the inverse cursor is at the very beginning, press
to jump back to the main menu screen. When the inverse cursor rests at some parameter,
the contents of the parameter can be modified. To modify a parameter, press to
increase the current parameter, or press to reduce it. In this screen the battery
type and capacity can be modified. The battery capacity ranges from 1-999 AH.
After the last digit of the battery capacity, Press or to select the type of
battery.

Settings can be saved by pressing until the last adjustable parameter is reached,
in this case will be the Battery Type. Press or to choose between Save or
Cancel. The inverse cursor will rest on the selected option.
Press to confirm the selection. If the Save option is chosen, then the parameters
will be saved. If Cancel was chosen, then parameters won’t be saved, and the screen will
jump back to the main menu interface. When saving, the controller will check and confirm
valid parameters. If the parameters are correctly set, and success message will appear as
shown below:
After successfully saving the parameters, press to exit to the main menu. The
controller should now have the correct parameters for the battery selected. If there is a
need to use different charging parameters, the controller is fully adjustable. Please refer
to the charge controller manual.

6. Find a clear sunlit area, free from overhanging tree branches, obstructions or shading.
The panel should be facing south, and the tilting angle should be adjusted as follows:
Note: To maximize the output, adjust the position of the kit regularly to track the sun movement
throughout the day
7. Remote Temperature Sensor (optional): The charge controller (ViewStar) has a built-
in temperature sensor. This is used for temperature compensation of the charging
parameters. During a hot summer day, the local temperature on the controller might
register a higher temperature than that from the battery if the battery is under shade.
For this reason, the controller also has a 2ERJ-3.81 port for a Remote Temperature
Sensor (Model: TS-R). The RTS can be placed next to the battery (ies). This optional
accessory can be purchased separately.

Frequently Asked Questions
Q. What type of batteries can be used with this kit?
A. Any sealed lead acid, gel, or flooded 12V battery (typically used in caravans,
motorhomes, boats etc.) is appropriate for use with this kit.
Q. Can this kit charge a 24V battery?
A. No, because this kit is designed to charge a 12V battery. Technically, it’s possible to
change solar panel connections to enable the kit to work in 24V mode; however, a
qualified, knowledgeable individual should only do this.
Note: unauthorized modification to 24V will void the warranty.
Q. Can the kit charge two or more 12V batteries connected in parallel?
A. Yes, it’s possible if the batteries have the same type and capacity and are wired in
parallel as a single 12V battery bank.
Q. Is there any risk that the solar kit will over charge my battery?
A. One of the functions of the solar charge controller is to ensure that your battery is not
over charged; therefore there is no risk of overcharge.
Q. Can I extend the battery leads?
A. Yes, it’s possible – please choose the same size of cable for extension. However, there
longer the extension, the greater the line loss. Bigger gauge will be required for longer
runs.
Q. Do I need to clean the solar panels?
A. Yes, it is recommended for better performance. Dust and dirt should first be swept off
the panel surface using a soft brush. When the sweeping is complete, use a wet cloth to
wipe the panel surface to remove remaining dirt and grime.
Q. Can rain damage the solar kit?
A. The solar panels are fully waterproof (IP66 class), the controller is not. We recommend
protecting the kit from rain, since water into controller may damage the internal circuitry.

Troubleshooting
Check all connections to ensure they are secure and clean
Check polarity of the battery connection and make sure the battery generates at
least 9V
Ensure the solar panels are exposed to sufficient light –ideally position them to
face the sun directly
For more information refer to the Troubleshooting section of the Solar Controller
Manual (skip anything which relates to load work in the controller manual as the
load terminals of the controller are not used)
