MPPT circuit solar charge controllers are considerably more
elaborate than standard PWM solar power controllers. The voltage of the solar
panel changes with time of day and temperature. The optimum voltage for battery
charging changes as the state of charge of the battery changes. The MPPT
photovoltaic charge controller matches these voltages and can result in 30%
more efficient transfer of power. This means that FORTUNER MPPT solar charge
controller can reduce the number of solar panels needed by up to 30% a
tremendous benefit. While only a small part of system price, a MPPT solar panel
charge controller can leverage the rest of the system to better performance.
