1

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 non-sealed / vented/ flooded / wet cell lead acid
batteries.

Do NOT equalize sealed / VRLA type AGM / Gel cell batteries UNLESS permitted by
battery manufacturer.
WARNING: Do NOT connect any inverters or battery charger into the load terminal of the charge
controller.
WARNING: 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.

General Information
The Renogy Solar Suitcases combine highly efficient Renogy Solar Panels and a fully adjustable
10 Amp ViewStar Series Charge Controller with an 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 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.
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 PWM 30ACC-ViewStar 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.

Four Charging Stages
The ViewStar charge controllers have a 4-stage battery charging algorithm for a rapid, efficient,
and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge, and
Equalization.
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.
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 in the ViewStar
controllers but it can be customizable as needed.
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 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.
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.
5
WARNING: 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.
WARNING: 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.
WARNING: 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
voltage.
Optional Components
Optional components that require a separate purchase:
Remote Temperature Sensor (TS-R): Measures the temperature
at the battery and uses this data for very accurate temperature
compensation. The sensor is supplied with a 6.6ft cable length that
connects to the charge controller. (Figure 1)
Figure 1
NOTE: The 10A ViewStar controller comes equipped with a
temperature sensor, but it is ONLY for the charge controller’s
temperature compensation, not the battery’s
temperature compensation.
LCD Display Tracer Meter (MT-50): Allows for real time monitoring of the
charge controller. Perfect for circumstances where the user cannot easily
access the controller or modify its parameters. It is supplied with a 5.9 ft.
cable and a mounting frame that connects to the RJ45 port on the
ViewStar. (Figure 2)
External Battery (RTC): Allows for access to the charge controller’s
saved settings, charge accumulation, and discharge accumulation without
connecting a deep cycle marine battery. It keeps track of the date/time for
automatic equalization charging purposes.

NOTE: It is not possible to measure actual SOC, but rather express it as a percentage of some
reference. In this case it is voltage alone (VC) or battery capacity over a time span (SOC).
VC. converts a reading from battery voltage to determine SOC by utilizing the charge
controller’s algorithm for known discharge. It is highly sensitive to temperature changes and battery
disturbances thus having less accurate battery charge statuses.
SOC is more accurate by keeping track of the voltage and current flow in and out of the
battery when reporting battery charge status. The SOC is determined by multiplying current by the
time for which it flowed.

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.

NOTE: The following rules MUST be obliged when setting custom parameters.
Rule 1: High Volt Disconnect > Charging limit voltage ≥ Equalization voltage ≥ Boost
voltage ≥ Float voltage > Boost return voltage;
Rule 2: High Volt Disconnect > Over Voltage Reconnect;
Rule 3: Charging Limit Voltage > Low voltage reconnect > Low voltage disconnect;
Rule 4: Charging Limit Voltage > Under voltage recover > under voltage warning;
Rule 5: Boost return voltage > Low voltage reconnect;
Charging Parameters Glossary
High Volt Disconnect—users can use the default parameters or assign a rated voltage value
that the charge controller will operate. When and if the charge controller experiences a voltage
higher than what is assigned, it will disconnect itself from the circuit; ceasing charge.
Charging Limit Voltage—depending on the batteries used, there might be a battery charging
limit voltage that is recommended for the battery. This parameter ensures that the charge
controller does not exceed the default or assigned rated charging limit voltage. This is usually
put into play to optimize and extend the life of the battery. Relatively speaking, the higher the
charging voltage then there is a correlation for reduced battery efficiency. (Likewise the lower
the discharge voltage affects battery efficiency.
Over-voltage Reconnect—In the event a charge controller experiences an over-voltage
condition set by the previous two parameters, then this reconnecting parameter is put into play
to direct the controller when it can connect and safely charge again. Typically over-voltage
reconnection is achieved when time has passed (ex. The sun setting), or when the over-voltage
condition is remedied ultimately reducing the voltage to a user defined charging voltage.
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.
Boost Return Voltage—if at any point, the battery voltage levels registers to be below the
boost return voltage for an extended period amount of time, then the charge controller will
commence the boost stage once again.

Low Voltage Reconnect—this parameter allows loads connected to the system will be able to
operate (not fully) again.
Under-voltage Recover—deals with the loads connected to the system. When batteries are
determined to be low due to them approaching low voltage disconnect, then the loads will be
shut off to give the batteries time to recover. This parameter sets the controller to shut off the
loads until it can reach the low voltage reconnect stage.
Under-voltage Warning—this parameter deals with the batteries themselves approaching the
under-voltage recovery state. The user should minimize loads before the charge controller
approaches a level where it will do this automatically to protect the battery from discharging
Low-voltage disconnect—prevents over-discharge of the batteries by automatically
disconnecting any loads. This extends battery life and is the precedent to being in an under
voltage state, recovering from the under voltage state, and finally reconnecting to normal
operational state.
Discharging limit Voltage—the user can set the “discharge” limit of a battery if they choose to
better protect the battery and expand its life. The following chart serves as an example of
voltages and their state of charges. Note that the higher the charging limit and lower the
discharge limit correlates with overall low battery life.
