MPPT Controllers – Tracer Series
Description
Compared to conventional PWM controller, MPPT technology increases the charge efficiency up to 30% and potentially decreases the required solar array power.
The ability to step-down from the higher solar array voltage to the lower battery bank voltage (to charge the batteries) greatly increases system design flexibility. The cable size can also be reduced because of the smaller current from the solar array.
The Tracer series controllers is ideal for off-grid solar systems and allows precise control of the charging and discharging of the battery. At the same time, the low voltage disconnect function (LVD) will prevent battery damage from over discharging.
