MPPT profile
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could
detect the real-time power of the solar Modulel and the maximum point of the I-V curve that make the
highest battery charging efficiency.
Current Boost
Under most conditions, MPPT technology will "boost" the solar charge current.
MPPT Charging：Power Into the controller (Pmax)=Power out of the controller (Pout)
Iin x Vmp= Iout x Vout
* Assuming 100% efficiency. Actually, the losses in wiring and conversion exist.
If the solar module's maximum power voltage (Vmp) is greater than the battery voltage, it follows that the
battery current must be proportionally greater than the solar input current so that input and output power are
balanced. The greater the difference between the Vmp and battery voltage, the greater the current boost.
Current boost can be substantial in systems where the solar array is of a higher nominal voltage than the
battery as described in the next section.
