4. Safety Information

• Always disconnect solar panels and battery power before installing or servicing the controller.
• Ensure proper polarity for all connections. Incorrect wiring can damage the controller and other components.
• Install the controller in a well-ventilated area, away from flammable materials and direct sunlight.
• Use appropriate circuit breakers or fuses for both solar panel and battery circuits.
• Do not charge lithium batteries when the temperature is below 0°C (32°F) to prevent damage.
• Ensure all connections are tight to prevent loose connections and overheating.

5. Setup and Installation

Follow these steps for safe and correct installation of your solar charge controller.

5.1 Wiring Sequence

1. Connect Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity. The controller will automatically detect the system voltage (12V/24V/36V/48V).
2. Connect Solar Panels: Next, connect the solar panels to the controller's PV input terminals. Ensure correct polarity.
3. Connect Load (Optional): If using the load output, connect your DC load to the load terminals.

Important: Always connect the battery first and disconnect the solar panels first when disassembling the system.

5.2 Parallel Operation

The Temank 80A MPPT controller supports parallel connection of up to 12 units to expand your solar system's capacity. When operating in parallel:

• Each controller must be connected to a separate solar array.
• All parallel controllers are connected to the same battery bank.
• Communication between controllers is achieved through dedicated communication lines.

To select or customize battery parameters:

• Navigate to the battery type setting on the LCD.
• Choose from preset options (Sealed, Gel, Flooded, LiFePO4, Lithium-Ion).
• For custom settings, select 'User' and adjust parameters such as Absorption Voltage, Float Voltage, Low Voltage Cutoff, and Load Timer according to your battery manufacturer's specifications.

6.3 Lithium Battery Activation

The controller can activate lithium batteries using solar panel energy. Ensure proper settings are configured for lithium batteries. Avoid charging lithium batteries below 0°C (32°F).

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your solar charge controller.

• Cleaning: Periodically clean the controller's exterior to prevent dust buildup, especially around ventilation openings.
• Connection Checks: Annually inspect all wiring connections for tightness and corrosion.
• Ventilation: Ensure the installation area remains well-ventilated. The internal turbofan activates automatically when the temperature exceeds 45°C and turns off below 40°C to maintain optimal operating temperature.
