45A MPPT Solar Charge Controller Regulator


2 year warranty

EPSOLAR Tracer series controller adopts MPPT technology (Maximum Power Point Tracking). The advanced tracking algorithm make the solar module operate at ideal voltage which the solar modules can produce the maximum available power. Compared to conventional PWM controller, MPPT technology increases the charge efficiency 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. Max. 150VDC input. So it 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.

Maximum Power Point Tracking is electronic tracking – usually digital. The charge controller looks at the output of the panels, and compares it to the battery voltage. It then figures out what is the best power that the panel can put out to charge the battery. It takes this and converts it to best voltage to get maximum AMPS into the battery. (Remember, it is Amps into the battery that counts). Most modern MPPT’s are around 97% efficient in the conversion. You typically get a 30-35% power gain in winter and 15-20% in summer. Actual gain can vary widely depending weather, temperature, battery state of charge, and other factors.
