Page 9: Maximum Power Point Tracking Technology
1.3 Maximum Power Point Tracking Technology Due to the nonlinear characteristics of the solar array, there is a maximum energy output point (Max Power Point) on its curve. Traditional controllers, adopting the switch charging technology and PWM charging technology, can't charge the battery at the maximum power point. - Page 10 that the MPPT mode can improve the usage of solar energy resources. According to our test, the MPPT controller can raise 20%-30% efficiency compared to the PWM controller. (Value may fluctuate due to the ambient circumstance's influence and energy loss.) Figure 1-2 Maximum Power Point Curve The panel may appear Multi-MPP as shading from clouds, trees, or snow in actual application.

Page 11: Battery Charging Stage
If the program works improperly after appearing Multi-MPP, the system will not work on the real max. power point. It may waste most solar energy resources and affect the system's normal operation. The typical MPPT algorithm, designed by our company, can track the real MPP quickly and accurately, improve the array's utilization rate and avoid wasting resources. - Page 12 B) Constant Charging When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant charging mode. This process is no longer MPPT charging. In the meantime, the charging current will drop gradually. The process is not the MPPT charging.
- Page 13 increases battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte. The controller will equalize the battery on the 28th of each month. The constant equalization period is 0~180 minutes. Suppose the equalization isn't accomplished at one-time. In that case, the equalization recharge time will be accumulated until the set time is finished.

Page 16: Pv Array Requirements
2.2 PV Array Requirements Serial connection (string) of PV modules As the core component of the PV system, the controller could be suitable for various types of PV modules and maximize converting solar energy into electrical energy. The series number of PV modules can be calculated according to the open-circuit voltage (Voc) and the maximum power point voltage (Vmpp) of the MPPT controller. -
Page 17: Mounting
refer to the value of I in the PV module specification. When the PV modules are connected in series, the I equals any PV module's I . When the PV modules are connected in parallel, the I equals the sum of the PV module's I . - Page 18 The controller requires at least 150mm of clearance above and below for proper airflow. Ventilation is highly recommended if CAUTION mounted in an enclosure. Figure 2-1 Mounting 1) Connect components to the charge controller in the sequence "① > ② > ③" shown above and ensure that the electrode polarity is connected correctly.
- Page 19 4) The Tracer BN series is a negative ground controller. Any negative solar, load, or battery connection can be earth grounded as required. Unplug the RTS, and the battery's temperature will be 25 ºC. Please connect the inverter to the battery rather than to the controller if the inverter is necessary.

4 Others 4.1 Protection PV Over Current The controller will limit the battery charging current to the Maximum Battery Current rating. Therefore an oversized solar array will not operate at peak power. PV Short Circuit When PV short circuit occurs, the controller will stop charging. Clear it to resume normal operation. - Page 29 Battery Over-discharge When the battery voltage reaches the Low Voltage Disconnect Voltage, the controller stops discharging the battery to protect the battery over-discharged. Battery Overheating The controller detects the battery temperature through the external temperature sensor. If the battery temperature exceeds 65ºC, the controller will automatically start the overheating protection to stop working and recover below 50 ºC.
