EPSolar Tracer MPPTEPSolar Tracer MPPT

The EPSolar Tracer MPPT series controller adopts the latest MPPT technology (Maximum Power Point Tracking) and advanced tracking algorithm to make the solar module operate at ideal voltage which the solar modules can product the maximum available power.
Compared to conventional PW M controller, MPPT technology increases the charge efficiency up to 30% and potentially decrease the power of solar array needed.
The ability to step-down the higher voltage solar module to recharge a lower voltage battery bank greatly increases system design flexibility. The cable size can be reduced because of the small current from the solar array.[/vc_column_text][vc_column_text]
