2. Safety Information

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the unit, personal injury, or property damage.

• Ensure all connections are correct and secure before applying power.
• Do not exceed the maximum PV open circuit voltage (Voc) of 100V for the XTRA1210N model. Exceeding this limit can damage the controller.
• Connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order.
• Install the controller in a well-ventilated area, away from flammable materials and direct sunlight.
• This device is designed for indoor use only. Protect it from moisture and dust.
• Only qualified personnel should perform installation and maintenance.

3. Product Overview

The XTRA-N series features an improved design and performance over its predecessor, the Tracer AN series. Key features include advanced MPPT technology for precise tracking of multiple Maximum Power Points (MPP) of the solar module, potentially yielding 20-30% more power. Lithium battery parameters can be adjusted via the LCD display.

4. Setup and Installation

Proper installation is crucial for the performance and longevity of your solar charge controller. Follow these steps carefully.

4.1 Mounting the Controller

• Choose a mounting location that is dry, well-ventilated, and protected from direct sunlight and moisture.
• Ensure there is sufficient space around the controller for heat dissipation.
• Mount the controller vertically on a non-flammable surface using appropriate screws.

4.2 Connection Sequence

Follow the connection sequence below to prevent damage to the controller or other components.

Figure 4: Diagram illustrating the recommended connection sequence for the solar charge controller. Step 1: Connect solar modules to form a 12V(2s) array. Step 2: Set up a 12V battery bank (battery not included). Step 3: Connect the charge controller to the battery bank. Step 4: Plug the solar module output into the PV input of the controller.

1. Step 1: Connect the Battery. Connect the battery to the controller's battery terminals (BATT1 or BATT2). Ensure correct polarity (+ to + and - to -). The controller will power on.
2. Step 2: Connect the Solar Panel. Connect the solar panel array to the controller's PV terminals. Ensure correct polarity. The controller will begin charging.
3. Step 3: Connect the DC Load (Optional). Connect your DC loads to the controller's load terminals. Ensure correct polarity.

Disconnection Sequence: Disconnect the load first, then the solar panel, and finally the battery.

4.3 Accessory Connections

The controller supports various accessories for enhanced monitoring and control (accessories not included).
