GWL/Power Solar Charge MPPT Regulators - GridFree Tracers Series

GWL/Power Tracer series solar charge 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.

GridFree Tracer has the ability to step-down the higher voltage solar array to recharge a lower voltage battery bank. 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 solar chargers have been tested to prove the support for the LiFePO4 technology.
