General Safety Information
•
•
•
•
Read all the instructions and cautions in
the manual before beginning the
installation.
Carefully read battery manuals before
operation.
•
There are no serviceable parts for this
controller. Do NOT disassemble or
attempt to repair the controller.
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.
Make sure all connections going into and
from the controller are tight.
Battery Safety
•
•
•
Use only sealed lead-acid, flooded, gel or
lithium 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.

General Information
The Renogy 100W & 50W Eclipse Lightweight Suitcase combines highly efficient monocrystalline
solar panels with a 10A PWM charge controller 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 models support 12V/24V deep cycle battery varieties such as
sealed-lead acid, gel, and flooded.
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.

Controller Operation
Step 1: Connect the battery. If the connection is correct, the controller screen lights up; otherwise,
check whether the connection is correct.
Step 2: Connect the solar panel. If sunlight is present and strong enough (the solar panel voltage
is greater than battery voltage), the sun icon on the LCD screen is on; otherwise, check whether
the connection is correct.
Step 3: Connect the load. Connect the load leads to the controller's load output terminal, and the
current shall not exceed the controller's rated current.
** The controller has a common positive pole inside. If grounding is needed, ground the
positive pole.

Five Load Working Modes
1. Pure light control (0): When sunlight disappears, and the light intensity drops to the starting
point, the controller initiates a one-minute delay (settable) to confirm the starting signal, and then
switches on the load for operation. When sunlight emerges, and the light intensity reaches the
starting point, the controller initiates a one-minute delay to confirm the shutting-down signal, and
then shuts down the output to stop the load's operation.
2. Light control + time control (1 to 14): The starting process is the same as pure light control.
After operating for a preset period (settable from 1 to 14 hours), the load stops operation
automatically.
3. Manual mode (15): In this mode, the user can switch the load on or off by the button, no matter
whether it's day or night.
4. Debugging mode (16): In cases of 6V with light signals, the load will be shut off. In cases of 5V
(varies according to the preset light-controlled voltage and system voltage) without light signals,
the load will be switched on. This mode enables fast check of the correctness of system
installation during installation and debugging.
5. Normal on (17): The energized load keeps in output state.

System Status Troubleshooting
Description
Troubleshoot
Battery over voltage
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.
Charge controller does not
charge during daytime when
the sun is shining on the
solar panels.
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.

Everything is connected
correctly, but the LCD on the
controller does not turn on
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.
Maintenance
For best controller performance, it is recommended that these tasks be performed from time to
time.
1. Check wiring going into the charge controller and make sure there is no wire damage or
wear.
2. Tighten all terminals and inspect any loose, broken, or burnt up connections
3. Make sure readings in the LCD and LED are consistent.
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 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. Yes, the charge controller is not waterproof.

Charging Parameters Glossary
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.
