Microcare MPPT Solar Charge Controllers are proudly South African. The Microcare MPPT utilizes PWM and integrated technology to provide greater than 96% efficiency from your solar panels. The actual charge current increase you will see varies primarily with module temperature and battery voltage. In comfortable temperatures, current increase typically varies between 10 to 25%, with 30% or more easily achieved with a discharged battery and cooler temperatures. What you can be sure of is that the Microcare MPPT charge controller will deliver the highest charge current possible for a given set of operating conditions. The ability to step down a high voltage solar array to a low voltage battery can save you money by reducing the size of the wire required and making the installation simpler and faster.

MPPT OPERATION DESCRIPTION:
Above and below schematics show how an MPPT functions during the course of a day.
In the morning, as soon as the MPPT detects that the Panel Voltage is at a usable level (MPPT charge entry voltage): it starts to charge the batteries at maximum efficiency in a BOOST mode which has a nominal voltage of 14.5V per 12V battery bank. If however the batteries are detected to not be uniformly discharged, the MPPT will go into EQUALISE mode to restore the battery bank balance before switching to BOOST mode as its primary charge mode..
The MPPT maintains this mode until the batteries reach the boost voltage and the charge current decreases to a level below a nominal changeable level of 6 Amps. The MPPT then steps down the charge voltage to a nominal voltage of 13.8V per 12V battery bank in FLOAT mode. The MPPT will attempt to maintain FLOAT mode for as long as the panel voltage is present. If no panel voltages present, the MPPT goes into a sleep state until it detects a rise in panel voltage indicating a new day for charging.
