The model MPPT 500 is a high
performance current boosting solar control. Through the use of
advanced microprocessor control and a high efficiency power
converter, power wasted in older PWM style solar controls is
converted into higher charge current. The MPPT 500 allows for
input voltage conversion. This increases the Maximum Power Point
voltage and allows for higher boost current over wider operating
conditions. A high accuracy digital volt and amp meter displays
battery voltage, photovoltaic current and battery charge
current. Proper battery charging is maintained over a wide
temperature range with the battery temperature sensor. Battery
float voltage is accurately regulated. Night time battery
discharge is eliminated through the use of a high efficiency
Schottky diode. Maximum input power to the MPPT 500 is 500
watts. Maximum photovoltaic input voltage is 100 VDC open
circuit.
When power is available from the solar panel, the MPPT 500
microprocessor measures and determines the optimum operating
point of the solar panel to produce the highest charge current
possible to the battery. There is no interaction between the
MPPT 500 and other battery charging systems. The float voltage
of the MPPT 500 is calibrated to 14.1 volts. When the battery
voltage reaches 14.1 volts the red Float LED turns on. At this
point, charge current to the battery will gradually diminish to
maintain the 14.1 float voltage. As soon as a load is turned on,
maximum charge current is applied to the battery. Temperature
compensation adjusts the float voltage to properly charge the
battery over a wide temperature range. When the battery is warm
the float voltage will drop and when the battery is cold the
float voltage will rise. MPPT 500 is well suited for flooded,
deep cycle and gel type batteries.
