Appearance

1. The RS485 waterproof port can provide a DC power of 5VDC/200mA, and have the short-circuit protection function. The port is isolation design for Tracer7810CPN/ Tracer7810CPN(BLE), and non-isolation design for other series. The pin definition is shown below:
   Pin| Definition
   ---|---
   1| +5VDC
   2| RS485-A
   3| RS485-B
   4| Power ground

CAUTION: When the RS485 port is not working, the waterproof cap must be installed to prevent water from getting in.

2. If the temperature sensor is short-circuited or damaged, the controller shall be charging or discharging at the default temperature of 25℃.
3. Only the Tracer-CPN (BLE) series are designed with the built-in Bluetooth module; please select as you require.

Wiring

• Connection sequence

1. Connect components to the controller in the sequence ①Battery > ②load > ③PV as shown above and pay much attention to the “+” and “-.” Please don’t connect the fast-acting fuse or circuit breaker during the installation. When disconnecting the system, the order will be reserved.
2. The Tracer-CPN/Tracer-CPN (BLE) controllers are common-negative; all the negative terminals can be grounded simultaneously, or anyone can be grounded.
   However, according to the practical application, the negative terminals of the PV array, battery, and load can also be ungrounded. Still, the grounding terminal on the shell must be grounded. It effectively shields electromagnetic interference from the outside and prevents some electric shock to the human body.

CAUTION

| A common-negative controller for a common-negative system, such as the motorhome, is recommended. The controller may be damaged if a common-positive controller is used and the positive electrode is grounded in the common- negative system.
---|---
3. Connect a fast-acting fuse in series with the battery positive (+). The fast-acting fuse must be 1.25 to 2 times the rated controller current. The installed distance is within 150mm. 4. After powering the controller, the battery LED indicator on the controller shall flash green. If it’s not green, please refer to chapter 10, Troubleshooting.

• Load self-test function
  The load is automatically turned ON after powering on the controller for 10s. After the load keeps ON status for 10s, the controller restores to the set working mode.

Accessories (optional) and Software

1. PC Software
   www.epever.com ——Solar Station Monitor

2. APP Software
   Please contact your business personnel or after-sales engineer to get the latest APP. For detailed operations to monitor the controller through the APP, please refer to the WiFi module or Bluetooth module user manual.
   
   Note: Only the Tracer-CPN series support the external Bluetooth module, the Tracer-CPN (BLE) series are designed with a built-in Bluetooth module. The controller is designed with waterproof function, but the WiFi/BLE module is not waterproof. Please take waterproof measures when using the WiFi/BLE module.

Protection

• PV Over Current
  The controller will limit the battery charging current to the rated charge current.
  Therefore an oversized solar array may not work at peak power.

• PV Short Circuit
  The controller will stop charging when the PV input is short-circuited or the short-circuit occurs at the low-power charging. Clear faults to resume work.

WARNING

| The controller may be damaged when the PV input is short-circuited on a high-power.
---|---

• PV Reverse Polarity
  The PV can be reversely connected with a controller when:
  ①Only the PV is connected to the controller. ②The battery is correct connected, and the PV open-circuit voltage is lower than 85V. WARNING| The controller will be damaged when the PV array is reversely connected, and the PV array’s actual power exceeds 1.5 times the rated charge power!
  ---|---
• Battery Reverse Polarity
  The battery can be reversely connected when the PV is disconnected or reversely connected. Correct the wire connection to resume work.

WARNING

| The controller will be damaged when the PV connection is correct and the battery connection is reversed!
---|---

• Battery Over Voltage
  When the battery voltage exceeds the Over Voltage Disconnect Voltage, the controller will stop charging the battery to protect the battery from being overcharged.

• Battery Over Discharge
  When the battery voltage is lower than the Low Voltage Disconnect Voltage, the controller will stop discharging the battery to protect the battery from being over-discharged.

• Battery Overheating
  The controller detects the environment temperature by the external temperature sensor. If the environment temperature exceeds 65ºC, the controller will stop working and recover below 55ºC.

• Lithium Battery Low Temperature
  When the battery temperature is lower than the low-temperature protection value, the
  Lithium battery charging/discharging is stopped. It resumes work when the battery temperature exceeds the low-temperature protection value.

• Load Overload
  If the load current exceeds 1.05 times the rated load current, the controller will disconnect the load after a delay time. Overloading must be cleared by reducing the load and restarting the controller.

• Load Short Circuit
  The load will be switched off when the short circuit (≥4 times rated load current) happens. The controller will automatically attempt to reconnect the load five times. Suppose short circuit protection still exists after the fifth attempt. In that case, the user has to clear the short circuit, restart the controller or wait for one night-day cycle (night time>3 hours).

• Temperature Sensor Breakdown
  When the temperature sensor is short-circuited or damaged, the controller will charge or discharge at 25°C by default to avoid damage to the battery caused by overcharge or over-discharge.

• High-voltage Transients
  The controller is protected against small high-voltage transients. In lightning-prone areas, additional external arrester is recommended.

Troubleshooting

Charging LED is off during the daytime, and sunshine falls on PV modules properly| PV array disconnection| Confirm that PV and battery wire connections are correct and tight
No LED indicator| Battery voltage may be less than 8.5V| Measure battery voltage with the multi-meter. A minimum of 8.5V can start up the controller
Battery LED flashes green quickly| Battery over voltage| Check if the battery voltage exceeds the OVD, and disconnect the PV
Battery LED is red ON solid| Battery over-discharged| The load will recover when the battery voltage is restored to or above the LVR (low voltage reconnect voltage).
Battery LED flashes red| Battery Overheating| The controller will resume when the battery temperature declines to 50ºC or below.
The load has no output| ①Load Overload| ①Please reduce the number of electric equipment.
②Restart the controller.
③wait for one night-day cycle (night time>3 hours).
①Load Short Circuit| ①Check carefully the loads’ connection and clear the fault.
②Restart the controller.
