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 increase charge efficiency up to 30% and decrease the power of solar array needed.
Tracer 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.
The Tracer series controller is for off-grid solar system and control the charging and discharging of the battery. The controller features a smart tracking algorithm inside that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery damage from battery over discharging.
