Maximum Power Point Tracking (MPPT) MPPT enables the charge controller to harvest the maximum energy available from the PV array and deliver it to the batteries. The MPPT algorithm continuously adjusts the array operating voltage so that the array continuously operates at its maximum power point.
Charge Controlling The charge controller can regulate PV array current for charging batteries at 12 and 24 volts. Figure 2 PV Charge Controller + + – + – + – – The charge controller controls how the batteries are charged by the DC source (the PV array). When charging, the charge controller regulates the charging voltage and current based on the amount of DC power available from the PV array and the current state of charge of the battery.
Three-Stage Battery Charging The three-stage charging process results in more efficient charging compared to on-off relay type or constant voltage solid-state regulators. The final float stage reduces battery gassing, minimizes electrolyte loss, and ensures complete battery recharging. Battery voltage and current vary during the three-stage charging process as shown in Figure 3 .

Equalization Charging The charge controller can be used to provide the battery bank with an equalize charge. Equalization is a deliberate overcharge designed to return each cell in the battery to optimum condition by reducing sulfation and stratification in the battery. The equalization charge is generally performed only on flooded, vented (non-sealed or “wet”) lead-acid batteries, as recommended by the battery manufacturer.
