*If your battery type is not a 12V LiFePO₄ battery, please complete step ② and then refer to the instructions below under "Battery Type Set Up" before step ③ connecting the solar panel.
2.7 Battery Type Set Up
If you are using a battery other than a 12V LiFePO₄, configuration is required via a RS485 to USB cable (sold separately) and software on your PC. Please follow the steps below:
Download and install the Linovision PC configuration software "LINOVISION Tool Box" from the link provided.
Connect the RS485 to USB cable, Red wire to terminal A, Blue wire to terminal B. Plug the USB end into your PC, then connect the XT60 interface to the battery.
Run the "LINOVISION Tool Box". Select the corresponding port. Set the device model to Solar-CMP10A/POE-804G-Solar, then click "Start" and "Config" to enter the configuration interface.
*If you need to manually configure a 24V battery, please fill in each parameter as if for a 12V system and set the system voltage level to 24V — the system will automatically double the values during actual operation.
2.8 Battery Type Set Up Reference
For gel and lead-acid batteries, the POE-SW804G-SOLAR controller comes with built-in charge curves and 12V/24V auto-detection so only battery type selection is needed.
For LiFePO₄ and NMC batteries, configuration must be done according to the actual battery specifications. The 24V information is for reference only. When filling in the parameters, you should still enter values based on a 12V system and only change the system voltage level to 24V.

3. Instruction
3.1 Charge Description
The controller employs Maximum Power Point Tracking (MPPT) technology to extract the maximum power from the solar modules. The tracking algorithm is fully automatic and requires no user adjustment. MPPT technology continuously tracks the array's maximum power point voltage (Vmp), which varies with weather conditions, ensuring optimal power harvesting throughout the day.
Charging of Lead-Acid or Gel Batteries:
The controller manages battery charging according to predefined charging profiles for different types of cells. If the cell type configured in the controller is lead-acid or gel battery, the entire charging process consists of three stages: fast charge, equalization charge, and float charge.

3.1.1 Lead Acid or Gel battery
a. Trickle Pre-Charge Stage:
At the beginning of the charging process, if the battery voltage is too low, the controller initiates a trickle pre-charge stage to protect the battery from damage caused by high current impacts. During this stage, the controller charges the battery with a small current. Once the battery voltage has sufficiently improved, the controller transitions to the fast charge stage.

b. Fast Charge Stage:
When the battery voltage has not yet reached the set threshold, the controller provides maximum solar power to charge the battery. During the fast charge stage, the solar panel and battery are directly connected, with the solar panel voltage clamped at the battery voltage.

c. Equalization Charge Stage:
Once the equalization charge voltage is reached, pulse width modulation (PWM) is activated. The controller maintains the battery voltage at the set level to prevent overcharging. This stage typically lasts for 2 hours before transitioning to the float charge stage.

d. Float Charge Stage:
In this phase, the battery requires minimal additional power. However, the controller continues to provide a weak charging current to meet the power consumption needs of small loads and compensate for self-discharge. This ensures that the battery remains in a fully charged state, extending its service life.

Constant-Voltage Charge Stage:
Once the battery voltage reaches the predefined level, the constant-current charge phase ends, and the controller enters the constant-voltage charge phase. As the charging process continues, the current gradually decreases from its maximum level based on the battery's saturation degree. For a single-string battery, this charge voltage is typically set to 4.2V. The specific voltage should be adjusted according to the parameters provided by the battery manufacturer. (Note: C represents the ratio between the cell's nominal capacity and the charging current. For example, for a cell capacity of 1000mAh, 1C means a charging current of 1000mA.)

3.2.1 Manual work mode
Manual Mode:
When used in an independent power system, the controller defaults to "manual ON/OFF" mode. By pressing the F1 button on the RC-3 remote control, users can manually activate or deactivate the controller output. If the controller is restarted, its operating status will remain unaffected.

3.2.2 Auto work mode
Automatic Operation with Two Modes:
The controller supports both light control mode and automatic mode, which can be used in conjunction with the LED driver to manage solar street lights. When the PV voltage remains continuously higher than the set light control voltage for more than two minutes (adjustable between 20 seconds and 10 minutes), the controller determines that the system is in daytime mode. Conversely, when the PV voltage remains continuously lower than the set light control voltage for more than two minutes, the controller determines that the system is in nighttime mode.

3.2.3 Test
Testing Mode:
This mode is designed for system testing and closely mirrors the complete light-control mode. The primary difference is the elimination of the delay time before optical signal determination, while all other functions remain intact. This facilitates the verification of proper system functionality during installation and testing.

4. Trouble Shooting
Phenomenon | Analysis | Solutions |
1. During the daytime, the PV indicator remains dark. 2. During the daytime, the load is active. 3. The load operates exclusively throughout the night. | There is an error in the connection of the solar panel cables. | 1. Verify the correctness of the solar panel cable connections. 2. Disconnect the solar panel cables from the solar controller, measure the open-circuit voltage (Voc), and then reconnect them. |
The load indicator is flashing rapidly, and the LED lamp is not functioning. | 1. The LED lamp cable is either open-circuited or short-circuited. 2. The LED lamp is either damaged or the connection between the LED chips does not meet the driver's specified range. | 1. Reverify the correctness of the LED lamp cable connections. 2. Disconnect the LED lamp cables, then reconnect them. |
The load indicator is flashing rapidly, and the LED lamp is also flashing. | After the LED lamp is powered on, it operates for a few seconds before turning off, and then the LED lamp begins to flash rapidly. | The series connection of LED chips exceeds the controller's output range. Please ensure that the number of LED chips in series is within the specified limits and refer to the parameter table for proper adjustment of the LED chip connections. |
The load indicator is flashing slowly. | The output power exceeds the controller's rated power. | Reduce the output current. |
5. Protection
Load Fault: In the event of any short circuit or open circuit in the controller's load connections, the controller will automatically provide protection, and the load indicator will flash rapidly. The system periodically detects the load fault to determine if it has been resolved. If the fault persists for more than 7 minutes, the controller will cease attempting to switch on the load until the next day, or until maintenance personnel have eliminated the fault and initiated a manual switch-on operation. | |
Overpower Protection: When the load power exceeds the rated power by 5%, the controller will activate the power protection mode to prevent potential damage. | |
Overcharge Protection: When the battery voltage during charging exceeds the safe threshold, the controller will automatically disconnect the charging circuit to prevent potential damage to the battery. | |
Overdischarge Protection: When the battery voltage drops below the safe threshold during discharge, the controller will automatically disconnect the load output to protect the battery. | |
PV Module Reverse Polarity Protection: In the event of reverse polarity connection of PV modules (not recommended), the controller will not be damaged and will resume normal operation once the wiring errors are corrected. |
Battery Polarity Protection: In the event of reverse polarity connection of the battery (not recommended), the controller will not be damaged and will resume normal operation once the wiring errors are corrected. | |
Temperature Sensor Fault Protection: In the event of a short circuit or damage to the temperature sensor, the controller will default to operating at 25°C. This prevents potential errors and damage to the battery that could result from inaccurate temperature compensation. | |
Overcurrent Protection: The system provides overcurrent protection with a 60-second delay when the current exceeds 1.25 times the rated current, featuring inverse time lag characteristics. |
