Description

Why we recommend buy MPPT Solar Controller? 

MPPT circuit solar controllers are considerably more elaborate than PWM. 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. The
MPPT charge controller matches these voltages and may end up in 30% more
efficient transfer of power. This means good MPPT solar charge controllers can
reduce the collection of solar panels needed by up to 30%- a tremendous benefit.
Even though the excess panels are purchased, benefits are realized in a Grid Tie
system because more electricity may also be sold back to the grid. Even as only a small
a part of system price, a MPPT solar panel charge controller can leverage the remainder
of the system to better performance.
