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, iTracer 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 iTracer controller with 10 amps of current flowing from iTracer controller to the battery. iTracer controller does not generate electricity! ITracer controller input energy and output energy are equal. Since the power voltage and current (amps × V) of the product, on the establishment of the following circumstances: (1) iTracer controller input power = output energy iTracer controller (2) Input voltage x Input current = output voltage x output current * Assumes 100% efficiency, ignored the wires and power loss during the conversion process. If the maximum power point voltage of the solar array (VMP) voltage is greater than the battery, battery charging current must be proportionally greater 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) is usually 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 voltage range lower than VMP. In 12V systems, for example, the battery voltage range is usually 11 ~ 15 V, but the solar array open circuit voltage corresponding to the VMP voltage 23V is usually about 16 or 17V. VMP photovoltaic array of arrays as the temperature rises. In hot weather, VMP may be close to or even lower than the battery voltage. In this case, compared with the conventional controller, iTracer controller little or hardly obtain energy. However, as long as the nominal voltage higher than PV system battery voltage, PV module VMP is always higher than the battery voltage. In addition, by reducing the current of the solar array, the wiring has been saved, so that iTracer controller even in the hot weather also has obvious advantages.
