The controller is for off-grid solar system and control the charging and discharging of the battery. Main function is protecting battery. The intelligent charging process has been optimized for long battery life and improved system performance.

In most cases, MPPT technology will "boost" the charging current of the solar power system. For example, a system might have 8 amps flowing from the solar array to the controller and 10 amps flowing from the controller to the battery The controller does not generate current, and the energy input to the controller is equal to its output energy. Since power is the product of voltage and current (volts x amps), the following holds true: (1) Controller input energy = controller output energy (2) Input voltage x input current=output voltage x output current*Assumes 100% efficiency, ignoring power losses in wires and conversion. If the maximum power point voltage (Vmp) of the solar array is greater than the battery voltage, the battery charging current must be proportionally greater than the solar array outpuf current so that the input and output power can be balanced. The greater the differe between the Vmp voltage and the battery voltage, the greater the current boost. Current enhancement is extremely important in the system because the maximum power point voltage (Vmp) voltage of the solar panels in a solar power system is usually higher than the battery voltage.
