6. Installation
6.1 Attentions
- Read all instructions before installation.
- Do not install in humid, high salt spray, corrosive, greasy, flammable, explosive, or dusty environments.
- Wear eye protection when installing open-type lead-acid batteries and rinse with clean water if acid contacts skin.
- Keep batteries away from metal objects to prevent short circuits.
- Ensure the surrounding environment is well ventilated, especially when batteries are charging and producing acid gas.
- Avoid direct sunlight and rain infiltration for outdoor installations.
- Ensure tight power connections and secure cables with clamps to prevent high heat, melting insulation, or fire.
- Only charge lead-acid and lithium-ion batteries within the controller's control range.
- The battery connection can be made to a singular battery or a bank of batteries.
- Select system cables according to 5A/mm² or less current density.
6.2 Requirements for the PV Array
The controller is designed to maximize solar energy conversion. The serial connection of PV modules should be calculated based on the open-circuit voltage (Voc) and maximum power point voltage (VMPP) of the MPPT controller. Refer to the specifications table for detailed values.
6.3 Wire Size
Wiring and installation must conform to national and local electrical codes. The PV array's output current varies, so calculate the minimum wire size based on the short circuit current (ISC) from the PV module's specifications. The PV array's ISC must not exceed the controller's maximum PV input current.
| Model | Max. PV input current | Max. PV wire size |
|---|---|---|
| Tracer1206/1210AN G3/G3 BLE | 10A | 4mm²/12AWG |
| Tracer2206/2210AN G3/G3 BLE | 20A | 6mm²/10AWG |
| Tracer3210AN G3/G3 BLE | 30A | 10mm²/8AWG |
| Tracer4210AN G3/G3 BLE | 40A | 16mm²/6AWG |
CAUTION:
The total voltage must not exceed the PV maximum open-circuit voltage when PV modules are connected in series. The PV maximum open-circuit voltage is 46V (Tracer**06AN G3/Tracer**06AN G3 BLE) or 92V (Tracer**10AN G3/Tracer**10AN G3 BLE) at 25°C environment temperature.
6.4 Mounting
Step 1: Determine the installation location and heat-dissipation space.
The controller requires at least 150mm of clearance above and below for proper airflow. Ventilation is highly recommended if mounted in an enclosure.
Figure 2-1: Mounting Clearance
Step 2: Connect the system in the order of battery → load → PV array, then disconnect in reverse order.
The schematic wiring diagram below illustrates the correct connection sequence.
Figure 2-2: Schematic Wiring Diagram
- Do not connect the circuit breaker or fast-acting fuse during wiring; ensure correct electrode polarity.
- A fast-acting fuse (1.25 to 2 times the controller's rated current) must be installed on the battery side, no longer than 150 mm from the battery.
- If an inverter is used, connect it directly to the battery, not to the load side of the controller.
Step 3: Grounding
Tracer-AN G3/Tracer-AN G3 BLE series are common-negative controllers. Negative terminals of the PV array, battery, and load can be grounded simultaneously, or any negative terminal can be grounded. The grounding terminal on the controller's shell must be grounded to shield electromagnetic interference and prevent electric shock.
CAUTION:
It is recommended to use a common-negative controller for common-negative systems (e.g., RV systems). The controller may be damaged if a common-positive controller is used and the positive electrode is grounded in a common-negative system.
Step 4: Connect accessories
- Connect the temperature sensor: Connect one end of the remote temperature sensor cable to the RTS interface (2) and place the other end close to the battery.
- Connect accessories for RS485 communication: The internal circuit of the RS485 port has no isolation design. Connecting an RS485 communication isolator to the port is recommended before communicating.
Step 5: Power on the controller
Connect the battery fast-acting fuse to power the controller. Check the battery indicator status (it should be lit green for normal operation). Connect the fast-acting fuse and circuit breaker of the load and PV array. The system will then operate in preprogrammed mode.
CAUTION:
If the controller is not operating properly or the battery indicator shows an abnormality, refer to the Troubleshooting section.

9. Troubleshooting
This section provides guidance for common issues and their solutions.
| Faults | Description | Troubleshooting |
|---|---|---|
| PV array open-circuit | When there is plenty of direct sunlight on the PV array, the LCD shows no PV input. | Confirm whether the connection of the PV array is correct and tight. |
| Battery voltage is lower than 8V | The wire connection is correct; the controller is not working. | Check the battery's voltage (at least 8V to activate the controller). |
| Battery over voltage | Battery frame blinks, fault icon blinks. | Check if battery voltage is higher than OVD (over voltage disconnect voltage) and disconnect PV array connection. |

For detailed graphical representations, please refer to the official user manual PDF: EPEVER Tracer MPPT Solar Charge Controller User Manual (PDF).
12. User Tips
- Understanding Model Numbers: The model number (e.g., '3210AN') directly indicates the controller's current and voltage capabilities. The first digit after 'Tracer' typically represents the current rating (e.g., '3' for 30A), and the second digit indicates the battery voltage compatibility (e.g., '2' for 12/24VDC). Always verify your model's specifications to ensure it matches your system requirements.
- Battery Type Selection: Correctly setting the battery type (Sealed, Gel, Flooded, LiFePO4, Li(NiCoMn)O2, or User-defined) is crucial for optimal charging and battery longevity. If using a custom battery, ensure all voltage parameters are accurately configured via the LCD, PC software, or mobile APP.
- Communication Setup: When connecting to a PC or mobile APP for monitoring and settings, consider using an RS485 communication isolator to protect the internal circuit of the RS485 port, especially in environments prone to electrical interference.
