The Tracer-BN series controller is for off grid solar system and control the charging and discharging of the battery. The controller features smart tracking algorithm that maximizes the energy from the solar PV modules and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.

The battery charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults. In addition, The Tracer-BN series controller has a RJ45 interface to allow communication with other accessory.

1.  Heat Sink: Cast aluminum heat sink to dissipate controller heat.

2.  Charging LED Indicator: Indicate that the battery is charging or not.

3.  Battery LED Indicator: Show charging status.

4.  Key: Switch the load on/off in the manual mode and clear the part of faults.

5.  Temperature Sensor Port: Connect remote temperature sensor to measure ambient temperature and make temperature compensation for charging and discharging.

6.  Solar module Terminals: Connect solar modules

7.  Battery Terminals: Connect batteries.

8.  Load Terminals: Connect loads.

9.  RS-485 Port (RJ45 interface): Connect with PC to MT50 to monitor or update firmware.

1. 12/24v Automatic identify or user-defined working voltage

2. Excellent heat dissipation. Using the integration of cast aluminum radiator shell, the controller can be natural cooling.

3. Advanced maximum power point tracking technology to optimize using the solar system. Peak conversion efficiency is as high as 98%

4. Widely used, automatic recognize day or night

5. Several load methods are supported to convenient for different demand.

6. Support 4 charging options: Sealed, Gel, Flooded and User-defined.

7. Adopting temperature compensation and correcting the charging and discharging parameters automatically, improving the battery lifetime.

8. Protection: Over temperature, over charging, PV and load short, PV (battery) revered, over current protection.

9. Actual power convenient and record function makes convenience to check the datum every day, every month and every year.

10. RS-485 ports via the open standard Modbus protocol are supported to meet different occasion of demand.

11. With supporting PC monitoring software and remote meter MT50, it is convenient to check the real-time data of controllers and set the parameters.

12. Support firmware update.

1. Connect components to the charge controller in the sequence as shown above and pay much attention to the “+” (Red) and “-“ (Black).

2. After installation, power the battery and check the battery indicator on the controller, it will be green. If it’s not green, please refer to chapter 5.

3. The battery fuse should be installed as close to battery as possible. The suggested distance is within 150mm.

NOTE: Unplug the RTS, the temperature of battery will be set to a fixed value 25 ºC. 

1. Remote Meter (Model: MT50)

The Digital remote meter displays system operating information, error indications, parameters setting and self-diagnostics.

2. Remote Temperature Sensor (Model: RTS300R47K3.81A)

Acquisition of battery temperature for undertaking temperature compensation of control parameters, the standard length of the cable is 3m ( length can be customized). the RTS300R47K3.81A connects to the port (3th) on the controller.

Note: Unplug the RTS, the temperature of battery will be set to a fixed value 25 ^oC.

3. Super Parameter Programmer ( Model: SPP-02)

The SPP-02 can realize one-key setting operation which is suitable for bulk quantity products setting in the projects.

4. USB to RS-485 converter (Model: CC-USB-RS485-150U)

USB to RS-485 converter is used to monitor each controller on the network using Solar Station PC software and update the firmware. The length of cable is 1.5m. The CC-USB-RS485-150U connects to the RS-485 Port on the controller.
