General Description
The Microcare Maximum Power Point Tracker Charge Controller is designed to provide maximum
power from the panels into the batteries. Using this system up to 30% more power can be extracted
from the panels than using shunt or series pass PWM controllers. The Microcare MPPT is able to
charge batteries of a lower voltage than the panel system.
A Liquid Crystal Display shows the status of the system and the data logging information. The unit
has various programmable charge regimes which automatically adjust the charge levels when first
starting up or if the battery falls below the minimum voltage.
The MPPT will read the battery voltage when first starting up and select whether it is a 12, 24, 36, or
48 volt battery system. It will then read the panel voltage and find the optimum power point. The
charging, battery values and charge modes are then adjusted. This series features a durable and
continuous 24 hour operation.
The compact and modular design makes installations easy and cost effective. It is a high quality
product that offers the best price/performance ratio in the industry.
