3 Installation Instructions 3.1 General Installation Notes Be very careful when working with batteries. Wear eye protection. Have fresh water available to wash and clean any contact with battery acid. Uses insulated tools and avoid placing metal objects near the batteries. Explosive battery gasses may be present during charging. Be certain there is sufficient ventilation.
3.2 Mounting 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.
4 Operation 4.1 MPPT Technology The Tracer-BN series utilizes Maximum Power Point Tracking technology to extract maximum power from the solar module (s). The tracking algorithm is fully automatic and does not require user adjustment, Tracer-BN series technology will track the array maximum power point voltage (Vmp) as it varies with weather conditions, ensuring that maximum power is harvested from the array through the course of the day.
Current VS. Voltage in 12V system Typical Battery Voltage Range Output power in 12V system Maximum Power Point Traditional Controller Operating Range Tracer Maximum Power Point Figure 4-1 Nominal 12V Solar Module I-V curve and output power graph The array Vmp is the voltage where the product of current and voltage (Amps×Volts) is greatest, which falls on the ―knee‖ of the solar module I-V curve as shown in Figure4-1.
Figure 4-2 Tracer-BN series MPPT charging algorithm · Bulk Charge In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is used to recharge the battery. · Boost Charge When the battery has recharged to the Boost voltage setpoint, constant-voltage regulation is used to prevent heating and excessive battery gassing. The Boost stage remains 120 minutes and then goes to Float Charge.
maintain the battery at the Float setpoint. Should the battery voltage remains below the boost reconnect charging voltage, the controller will exit Float stage and return to Bulk charging. · Equalize WARNING: Risk of explosion! Equalizing flooded battery can produce explosive gases, so well ventilation of battery box is necessary. CAUTION: Equipment damage! Equalization may increase battery voltage to the level damaging to sensitive DC loads.

4.4 Setting Operation Three methods to configure the controller: 1–Remote meter, MT50/MT100 (Use standard twisted net cable, model: CC-RS485-RS485-200U-MT). 2–Super parameter programmer, SPP-01(Use standard twisted net cable, model: CC-RS485-RS485-200U). One-key easily configure and apply to batch setting. 3–PC monitoring setting software ―Solar Station Monitor‖（Use USB to RS485 converter cable with model: CC-USB-RS485-150U.
WARNING: Do not use the standard twisted-net cable to connect the device and PC net interface, or the permanent damage will occur. •Load Set Mode 1．Manual Control (default) 2．Light ON/Off 3．Light ON+ Timer 4．Time Control •Battery Type 1．Gel 2．Sealed(default) 3．Flooded 4．User NOTE: Please refer to user guide or contact with the sales for the detail of setting operation.
5 Protections, Troubleshooting and Maintenance 5.1 Protection · PV Array Short Circuit When PV short circuit occurs, the controller will stop charging. Clear it to resume normal operation. · PV Overvoltage If PV voltage is larger than maximum input open voltage 150V, PV will remain disconnected and warning until the voltage falls safely below 145V. PV voltage cannot be too high, otherwise it may damage the controller, please verify the PV parameter.
discharging at the default temperature 25℃ to prevent the battery damaged from overcharging or over discharged. · Over Temperature Protection If the temperature of the controller heat sinks exceeds 85℃, the controller will automatically start the overheating protection and recover below 75℃. 5.
NOTE: If all the led are off, please check the voltage of battery. At least 9V voltage to activate the controller. NOTE: If the charging led is steady off without miswire, check the PV input voltage which should be higher than battery’s. 5.3 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for best performance. Check that the controller is securely mounted in a clean and dry environment.
6 Warranty The Tracer-BN Series charge controller is warranted to be free from defects for a period of TWO (2) years from the date of shipment to the original end user. • Claim Procedure: Before requesting warranty service, check the Operation Manual to be certain that there is a problem with the controller. Return the defective product to us with shipping charges prepaid if problem cannot be solved. Provide proof of date and place of purchase.
