5. Setup and Installation
Follow these steps for proper installation of your solar charge controller. Ensure all connections are secure and correct to prevent damage or injury.
Figure 4: Panel Connection Overview
- Connect Solar Panel (PV) to Controller: Connect your solar panels to the MC4 input connectors on the controller. Ensure correct polarity (positive to positive, negative to negative).
- Connect Battery to Controller: Connect your battery to the XT60 battery terminals on the controller. Observe correct polarity. The controller will auto-detect 12V/24V for Lead Acid, Gel, or AGM batteries. For Lithium batteries, manual setup is required after connection.
- Connect Load Devices (Optional): Connect your DC load devices to the round 2-pin load output. Ensure the total current draw does not exceed the controller's rated load current.
- Connect RS485 (Optional): If using remote monitoring, connect the RS485 cable to the RS485 port on the controller.
- Connect Temperature Sensor (Optional): For optimal battery charging, connect the external temperature sensor to the designated port. Place the sensor near the battery.
Safety Warning: Always ensure correct cable connections and polarity. Incorrect wiring can lead to short circuits, reverse polarity, and potential damage to the controller, battery, or other connected devices. Disconnect power sources before making or changing connections.
6. Operating Instructions
6.1 Battery Type Selection
The controller is set to 4S LiFePO4 Lithium by default. For other battery types (Lead Acid, Gel, AGM, Ternary Lithium), you will need to manually configure the battery type and voltage settings. Refer to the detailed user manual PDF for specific instructions on changing battery settings via the RS485 interface or other configuration methods.
6.2 Charging Stages
The controller employs a multi-stage charging algorithm to optimize battery life and performance.
Figure 5: 4-Stage Charging for Gel or Lead Acid Batteries
- Trickle Charging: Starts with a small current to protect the battery when deeply discharged.
- Fast Charging: Maximizes charging efficiency and limits PV panel voltage to battery voltage.
- Equalization: Constant voltage charging to prevent overcharging (for certain battery types).
- Floating: Charging with a small current to maintain battery capacity once fully charged.
Figure 6: 4-Stage Charging for Lithium Batteries
- Trickle Start: Initial charging phase for deeply discharged batteries.
- Constant Current Charging: Charges the battery with a constant current until a certain voltage is reached.
- Constant Voltage Charging: Maintains a constant voltage while the current decreases.
- Pausing: Stops charging when the charging current is low enough (typically around 0.02C to 0.07C).
7. Remote Monitoring and Cloud Access
The LINOVISION Solar-CMP10A supports RS485 ModBus for remote monitoring and control, enabling integration with the Linovision RemoteMonit Cloud Platform. This feature allows you to monitor the status of your solar panels, solar trailers, or solar-powered cameras from anywhere.
Figure 7: Cloud Data Management System
To utilize cloud access, the controller needs to be bundled with an IOT-C101 or IOT-R51W Gateway. Key benefits of the cloud platform include:
- Remotely monitor solar charging status and sensor data.
- View cellular traffic usage from Linovision vSIM router (IOT-R51W) and refill data plans directly.
- Customize group display of camera video and IoT sensors on one page.
