Maximum power point tracking mode is completely automatic and does not require user adjustment. When the array maximum power point with the environmental conditions change, Tracer-BN array controller automatically track the maximum power point, ensuring access to day maximum energy from the solar array. ? Improve under the current most cases, the maximum power point tracking technology to "improve" the solar power system charging current. For example, a system may have 8 Amps of current from the solar arrays flows into the Tracer-BN controller with 10 amps of current from the Tracer-BN controller to the battery. Tracer-BN controller does not generate electricity! Tracer-BN controller input energy and output energy are equal. Since the power voltage and current (Volts x Amps) of the product, on the establishment of the following circumstances: (1) Tracer-BN controller input power = output energy Tracer-BN controller (2) Input voltage x Input current = output voltage x Output current * Assuming 100% efficiency, ignored the wires and power loss during the conversion process. If the maximum power point of the solar array voltage Vmp larger than the battery voltage, battery charging current must be proportionally better than the solar array output current, so in order to balance the input and output power. Vmp voltage and the battery voltage difference between the larger, the greater the current enhancement. Current enhancements in the system is extremely important, because solar power system solar panel maximum power point voltage Vmp voltage is typically higher than the battery voltage. ? When compared to traditional controllers Superiority charge conventional controller directly to the solar array to the battery. This requires that the solar array is operating within the normal range of less than Vmp voltage. In 12V system for example, battery voltage range of usually 11-15 V, but the voltage of the solar array Vmp typically about 16 or 17V. Vmp solar photovoltaic array as the temperature of the array increases. In hot weather, Vmp may be close to or even lower than the battery voltage. In this case, compared with conventional controllers, Tracer-BN controller little or hardly obtain energy. However, as long as the nominal voltage higher than PV system battery voltage, PV modules Vmp always higher than the battery voltage. In addition, by reducing the current of the solar array, the wiring has been saved, so that Tracer-BN controller even in the hot weather also has obvious advantages.
