EPSOLAR Tracer series controller adopts MPPT technology (Maximum Power Point Tracking). This advanced tracking algorithm makes the solar module operate at an ideal voltage where the solar modules can produce the maximum available power. Compared to conventional PWM controllers, MPPT technology increases the charge efficiency by up to 30% and decreases the power of solar array needed.
The regulator has the ability to step-down the higher voltage solar array to recharge a lower voltage battery bank. This allows on grid solar modules or thin film modules to charge the off-grid battery, and the cable size can be reduced because of the small current from the solar array.
