MPPT Solar Charge Controller
Technical DataProduct Introduction
ECO-N-MPPT is the intelligent, cost-effective choice for low-power
applications that require maximum charging efficiency. Phocos’
high-performance maximum power point tracking (MPPT)
algorithm ensures optimal charging current from your panel/array
in all conditions. This results in up to 30% higher power yield than
conventional PWM charge controllers. This added efficiency paired
with Phocos’ precision 4-stage, temperature-compensated (external
temperature sensor included) charge regime significantly extends
battery lifespan, reducing number of battery replacements over the
useable life of the system.
The encapsulated housing and corrosion-resistant wire terminals
protect the ECO-N-MPPT from the harshest environments. An
intuitive, 3-LED interface display basic system status data including:
charge on/off, low battery warning, high/low-voltage disconnect,
and load over current/short circuit.
