General Safety Informat
ion
Read and follow all instructions and precautions mentioned in this user manual before
beginning the installation.
There are no serviceable parts for this controller. Do NOT disassemble or attempt to repair
the controller.
Make sure all connections going into and from the controller are tight.
Battery Safety
Use only sealed lead-acid, flooded, gel or lithium (LFP) batteries which must be deep cycle.
Explosive battery gases may be present while charging. Be certain there is enough
ventilation to release the gases.
Be careful when working with large lead acid batteries. Wear eye protection and have
fresh water available in case there is contact with the battery acid.
Carefully read battery manuals before operation.
Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.
Recycle battery when it is replaced.
Over-charging and excessive gas precipitation may damage the battery plates and
activate material shedding on them. Too high of an equalizing charge or too long of one
may cause damage. Please carefully review the specific requirements of the battery used in
the system.
Equalization is carried out only for nonsealed / vented/ flooded / wet cell lead acid batteries.
Do NOT equalize sealed / VRLA type AGM / Gel cell batteries UNLESS permitted by
battery manufacturer.

General Information
Negative ground controller.
The Renogy Solar Suitcase combine highly efficient monocrystalline solar panels with a 20A
Voyager charge controller to create an easy-to-use, ‘plug and play’ system.
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.
This system is specifically designed for mobile off-grid applications, where space and weight
limitations are abundant. The Solar Suitcase models support 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.

PWM Technology
Key Features
The Voyager utilizes Pulse Width Modulation (PWM) technology for battery charging. Battery
charging is a current based process so controlling the current will control the battery voltage.
For the most accurate return of capacity, and for the prevention of excessive gassing pressure,
the battery is required to be controlled by specified voltage regulation set points for Absorption,
Float, and Equalization charging stages. The charge controller uses automatic duty cycle
conversion, creating pulses of current to charge the battery. The duty cycle is proportional to
the difference between the sensed battery voltage and the specified voltage regulation set
point. Once the battery reached the specified voltage range, pulse current charging mode
allows the battery to react and allows for an acceptable rate of charge for the battery level.
04
Four Charging Stages
Equalization: Is carried out every 28 days of the month. It is intentional overcharging of the
battery for a controlled period of time. Certain types of batteries benefit from periodic equalizing
charge, which can stir the electrolyte, balance battery voltage and complete chemical reaction.
Equalizing charge increases the battery voltage, higher than the standard complement voltage,
which gasifies the battery electrolyte.
Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available solar
power to recharge the battery and is equivalent to constant current.
Float Charge: After Boost Charge, the controller will reduce the battery voltage to a float
voltage set point. Once the battery is fully charged, there will be no more chemical reactions and
all the charge current would turn into heat or gas. Because of this, the charge controller will
reduce the voltage charge to smaller quantity, while lightly The Voyager charge controller has a
4-stage battery charging algorithm for a rapid, efficient, and safe battery charging. They include:
Bulk Charge, Boost Charge, Float Charge, and Equalization.charging the battery. The purpose
for this is to offset the power consumption while maintaining a full battery storage capacity. In the
event that a load drawn from the battery exceeds the charge current, the controller will no longer
be able to maintain the battery to a Float set point and the controller will end the float charge
stage and refer back to bulk charging.
Boost Charge: When the battery has charged to the Boost voltage set-point, it undergoes an
absorption stage which is equivalent to constant voltage regulation to prevent heating and
excessive gassing in the battery. The default time for this is 120 minutes for the Voyager.
Once equalization is active in the battery charging, it will not exit this stage unless
there is adequate charging current from the solar panel. There should be NO load
on the batteries when in equalization charging stage.
Over-charging and excessive gas precipitation may damage the battery plates
and activate material shedding on them. Too high of equalizing charge or for too
long may cause damage. Please carefully review the specific requirements of the
battery used in the system.
Equalization may increase battery voltage to a level damaging to sensitive DC
loads. Ensure that all load allowable input voltages are greater than the equalizing
charging set point volta.

Battery over voltage
For best controller performance, it is recommended to preform maintenance tasks
occasionally.
1. Check wiring going into the charge controller. Make sure there is no wire damage or
wear.
2. Tighten all terminals and inspect any loose, broken, or burnt connections
3. Confirm LCD and LED readings are consistent.
System Status Troubleshooting
Maintenance
Description Troubleshoot
Use a multi-meter to check the voltage of the battery.
Make sure the battery voltage is not exceeding the
rated specification of the charge controller.
Disconnect battery.
Confirm that there is a tight and correct connection
from the battery bank to the charge controller and the
solar panels to the charge controller. Use a
multi-meter to check if the polarity of the solar
modules has been reversed on the charge
controller’s solar terminals.
Check the rated battery voltage. The LCD will not
display on the charge controller unless there is at
least 9V coming from the battery bank.
Charge controller does not
charge during daytime when
the sun is shining on the
solar panels.
Everything is connected
correctly, but the LCD on the

Frequently Asked Questions
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 overcharge my battery?
A. One of the functions of the solar charge controller is to ensure that your battery is not
overcharged; 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. A bigger gauge will be required for longer runs.
Q. Do I need to clean the solar panels?
A. Yes, it is recommended to clean glass surface 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 the remaining dirt and grime.
Q. Can rain damage the solar kit?
A. The solar panels and charge controller are both fully waterproof (IP66, IP65).

Equalization Voltage—equalization voltage is a corrective over-charge of the battery. The
user should consult their battery manufacturer regarding specific battery equalization capacity.
This parameter sets the equalization voltage to set the battery at when it reaches the
equalization state.
Boost Voltage—users should check with their battery manufacturer for proper charging
parameters. In this stage, users set the boost voltage where the battery will reach a voltage level
and remain there until the battery undergoes an absorption stage
Float Voltage—once the charge controller recognizes the set float voltage, it will commence
floating. The battery is supposed to be fully charged in his state, and the charge current is
reduced to maintain battery stability levels.
