The LVC Series MPPT controller utilizes maximum power point tracking
technology to extract the maximum power from the solar array to charge the battery.
The maximum power point tracking mode is completely automatic and does not
require user adjustment. When the maximum power point of the array changes with
environmental conditions, the controller automatically tracks the maximum power
point of the array to ensure that the largest energy of the day is taken from the solar
array.
The traditional controller directly connects the solar array to the battery while
charging. This requires the solar array to operate at voltages typically below the
Vmp voltage. Taking the 12V system as an example, the battery voltage range is
usually 11-15V, but the Vmp voltage of the solar array is usually about 16 or 17V.
The graph below shows the current vs. voltage and output power curves for a
typical off-grid solar cell with a nominal voltage rating of 12V.
