Renogy 2775 E All off Grid Solar System User Manual
Important Safety Instructions
Renogy® Official- offer This manual contains important safety, installation, and operating instructions. The following symbols are used throughout the manual to indicate potentially dangerous conditions or important safety information. ..
- Read all the instructions and cautions in the 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 batteries which must be a 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 the 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 the battery manufacturer.
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.
Key Features
- High Efficiency monocrystalline solar cell with a high conversion rate
- Lightweight and durable design with a side bag
- Easy-to-read LCD displaying solar charge information
- Upgraded 3-stage PWM charging algorithm
- Protection against: overcharge, over-discharge, overload, and short-circuit.
- Positive ground controller.
- A wide range of load working modes facilitates the product’s application to different types of loads.
Included Components
10A PWM Charge Controller
Regulates the voltage and amperage coming from the solar panel to properly charge the battery bank.
MC4 to Alligator Clips w/ Fuse
Used for connecting the charge controller to the battery. The entire cable from the charge controller to the alligator clips measures 3.3 feet with an inline fuse of 10A.
Controller Panel Structure
Controller Operation
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 the 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.

Setting Menu on LCD Screen
Long press the red button in any mode to enter the load mode setting interface, and the load mode begins to flash. Short press the button to adjust the load mode, and long press the button again to save and exit mode setting or wait for 10s to let the system save and exit automatically.
Five Load Working Modes
- 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.
- 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.
- 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.
- 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 a fast check of the correctness of system installation during installation and debugging.
- Normal on (17): The energized load keeps in the output state.
| LED Display | Mode |
| 00 | Pure light control mode |
| 01-14 | Light control + time control (1 to14 hours) |
| 15 | Manual mode (default) |
| 16 | Debugging mode |
| 17 | Always on mode |
Manually Switching On/Off Load
When the load mode is set to 15 (manual mode), short press the button (non-setting mode) in any interface to switch on or off the load.
Note: As load start is a type of soft start, the display of the load icon on the LCD screen will be delayed after the load is switched on.

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. |
| The charge controller does not change during the 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 multimeter 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.
- Check the wiring going into the charge controller and make sure there is no wire damage or wear.
- Tighten all terminals and inspect any loose, broken, or burnt-up connections
- Make sure readings in the LCD and LED are consistent.

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 its state, and the charge current is reduced to maintain battery stability levels.
