MPPT Maximum Power Point Tracking
MPPT enables the SolarMax Charge Controller to utilize the maximum power available from the PV array. A solar panel
has a variable power output. Power is measured in watts and is the product of the voltage multiplied by the current.
The SolarMax constantly searches for this maximum power point, using a patented MPPT algorithm, to ensure that you
get the maximum
Charge Controller
A maximum power point tracker (or MPPT) is a high efficiency DC to DC converter which functions as an optimal
electrical load for a solar array, and converts the power to a voltage and current level which is optimum for charging
batteries.
The benefits of MPPT regulators are greatest during cold weather, on cloudy or hazy days or when the battery is deeply
discharged. The SolarMax Charge Controller also monitors battery voltage and temperature to prevent overcharging.
The Charge Controller can accept PV open cell voltages (Voc) up to 230 volts for charging lead acid batteries. SolarMax
produces up to 100 amps of charging current for battery voltages between 24 and 72 volts.
When charging, the SolarMax regulates the voltage and output current to the battery, based on the amount of power
available from the PV array, the state of charge of the battery and the temperature of the battery bank.
