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 output 

current so that the input and output power can be balanced. The greater the difference 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.

Traditional controllers connect the solar array directly to the battery during 

charging. This requires the solar array to operate in a voltage range that  is 

typically lower than the maximum power point voltage. Taking a 12V system 

as an example, the battery voltage range is usually 11-15 V, but the  

maximum power point voltage of a solar array is usually around 16 or 17V.

The solar PV array maximum power point voltage Vmp is the voltage at 

which the output power (amps x volts) is at its maximum. Since traditional 

controllers do not always operate at the maximum power point voltage of

 the solar PV array, energy is wasted that could otherwise be used to charge 

batteries and  power system loads. The greater the difference between the 

battery voltage and the maximum power point voltage of the solar PV 

array, the more energy  is wasted. This series of controllers will always 

operate at the maximum power point, reducing energy waste compared to 

traditional controllers. The figure below shows the nominal 12V solar 

cell I-V curve and output power graph.
