5. Setup and Installation
Follow these steps for safe and correct installation of your TRIRON 1206N solar charge controller.
- Mounting: Choose a suitable location for mounting the controller. It should be indoors, protected from direct sunlight, high temperatures, and water. Ensure good ventilation. Mount the controller vertically on a wall or panel using the provided mounting holes.
- Wiring Sequence: Connect the components in the following order to prevent damage:
- Step 1: Connect the Battery: Connect the battery to the controller's battery terminals (BATT+/-). Ensure correct polarity. The controller will detect the system voltage.
- Step 2: Connect the Load: Connect the DC load to the controller's load terminals (LOAD+/-). Ensure correct polarity.
- Step 3: Connect the Solar Panel: Connect the solar panel array to the controller's PV terminals (PV+/-). Ensure correct polarity.
WARNING: Always connect the battery first, then the load, and finally the solar panel. Disconnect in the reverse order: solar panel, then load, then battery. Incorrect wiring sequence can damage the controller and other components.
- Temperature Sensor (RT-S): Connect the optional remote temperature sensor to the designated port. This improves battery charging accuracy by compensating for temperature variations.
- Communication Ports: If using external communication modules (e.g., MT50, eBox-WIFI-01), connect them to the RS485 SLAVE port. The controller also features dual USB ports (5V, 2.2A max) for charging small devices.

6.2. Battery Type Setting
The controller supports various battery types. It is crucial to set the correct battery type for optimal charging and battery longevity.
- Supported types include: Sealed, Gel, Flooded, LiFePO4, Li-NiCoMn, and User-defined Lithium battery.
- Consult the display module manual or communication software for instructions on how to select and configure the battery type.
6.3. Load Work Modes
The controller offers multiple load control modes:
- Manual Control: The load can be turned ON/OFF manually via the controller's buttons or communication software.
- Light ON/OFF: The load automatically turns ON at dusk and OFF at dawn.
- Light ON + Timer: The load turns ON at dusk and stays ON for a set duration (e.g., 2 hours, 4 hours).
These modes can be configured through the display module or external communication tools.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Loose connections can cause voltage drops and overheating.
