4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully:
4.1. Wiring Steps
To connect wires to the terminal block:
- Screw the adjustment screw counter-clockwise until the metal plate moves down.
- Insert the stripped wire end into the opening between the plate and the top of the terminal hole. Do not insert it underneath the plate.
- Screw the adjuster clockwise until the plate moves upwards, securely clamping the wire in the terminal hole. Ensure a tight connection.
4.2. Connection Sequence
WARNING: The connection sequence is critical. Failure to follow this sequence may damage the controller and void the warranty.
- Connect the Battery: Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will power on once the battery is connected.
- Connect the Solar Panel: Connect the solar panel to the charge controller. Ensure correct polarity (+ to + and - to -).
- Connect the Load: Connect your DC load to the charge controller.
4.3. Disconnection Sequence
To disconnect the system, follow the reverse order:
- Disconnect the Load.
- Disconnect the Solar Panel.
- Disconnect the Battery.
5. Operating Instructions
The controller automatically manages the solar panel and battery charging and discharging processes. The LCD displays real-time system status and parameters.
5.1. Battery Voltage Recognition
The controller automatically detects whether the system is 12V or 24V. Ensure the battery has enough voltage (above 8V) for the controller to recognize the system voltage upon initial connection.
5.2. Adjustable Parameters
You can set various operational parameters using the controller's interface buttons. Refer to the on-screen menu for navigation:
- Float Voltage (Overcharge Floating Charge): This sets the voltage at which the battery charging transitions from bulk to float charge, maintaining the battery at full capacity without overcharging. (e.g., 13.7V/27.4V for 12V/24V systems).
- Discharge Reconnect Voltage: This is the voltage level at which the load will automatically turn back on after being disconnected due to low battery voltage.
- Discharge Stop Voltage (Over Discharge Protection): This sets the minimum battery voltage at which the load will be disconnected to protect the battery from deep discharge. (e.g., 10.7V/21.4V for 12V/24V systems).
- Work Mode: Configure the load output operation, such as setting a timer for the load to turn on after sunset for a specified number of hours.
5.3. USB Charging
The integrated dual USB ports provide a maximum output of 3A for charging compatible electronic devices. Note that the controller may not display the current output for USB ports.
5.4. Low Voltage Protection
For battery protection, if the battery voltage drops below 8V, the solar controller will automatically turn off. The LCD will also become unavailable at this point.
6. Battery Type Settings
This controller is compatible with various battery types. It is essential to select the correct battery type setting for optimal charging and battery longevity. Use the controller's interface to navigate to the battery type setting and choose the appropriate option:
| Setting Code | Battery Type |
|---|---|
| b01 | Sealed Lead-Acid Battery |
| b02 | Gel-Type Lead-Acid Battery |
| b03 | Open Lead-Acid Battery (Flooded) |
| b04 | Lithium Ternary Battery |
| b05 | LiFePO4 / Lithium Ferro Phosphate (LFP) Battery |
Make sure to select the appropriate setting on your controller to match your battery type.

8. Troubleshooting
This section addresses common issues you might encounter during the operation of your amiciSmart Solar Charge Controller.
8.1. Controller Not Working / LCD Unavailable
- Ensure the battery is connected first and has sufficient voltage (above 8V) for the controller to recognize it.
- Check all wiring connections for correct polarity and secure terminals. Loose connections can prevent operation.
8.2. No Charging Indication
- Verify solar panel connection and ensure it is receiving adequate sunlight.
- Confirm the battery type setting (b01-b05) matches your battery. An incorrect setting can affect charging.
- Note: Some models may not have a blinking arrow indicator for charging. Refer to the LCD for voltage readings to confirm charging status.
8.3. Load Not Turning On
- Check the battery voltage; if it's below the discharge stop voltage, the load will be disconnected for protection. The load will reconnect when the battery voltage rises to the discharge reconnect voltage.
- Verify the load connection and ensure it's not short-circuited. The controller has short-circuit protection.
- Check the "Work Mode" settings to ensure the load is configured to operate as desired.
8.4. Controller Overheating / Burning Smell
- Immediately disconnect all connections (load, solar panel, battery). This indicates a potential fault or overload.
- Ensure the controller is installed in a cool, well-ventilated area, away from direct heat sources.
- Avoid exceeding the rated current for USB ports or load terminals.
- Contact customer support if the issue persists after ensuring proper installation and load.
8.5. Controller Does Not Auto Wake-Up in Morning
- If the battery voltage dropped too low overnight (below 8V), the controller might enter a deep protection state. It may require a manual reset by disconnecting and then reconnecting the solar panel to restart charging.
9. Maintenance
To ensure long-term performance and reliability of your amiciSmart Solar Charge Controller, follow these maintenance guidelines:
- Regular Inspection: Periodically check all wiring connections for tightness and corrosion. Loose or corroded connections can lead to poor performance or damage.
- Cleanliness: Keep the controller clean and free from dust, dirt, and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure the installation area remains well-ventilated to prevent overheating. Do not block the ventilation openings on the controller.
- Environmental Conditions: Avoid exposing the controller to excessive moisture, direct water spray, or extreme temperatures outside its specified operating range.
