microcare 20 amp led mppt regulator with load shed

 

 

downloadThe Microcare 20 amp MPPT Regulator has been developed to create a cost effective solution for small installations. The Microcare 20 amp MPPT Regulator continually calculates the module’s maximum power point. When a 75W PV panel is connected directly to a battery, charging at 12 volts, its power production is artificially limited to about 53 watts. This wastes 22 watts or nearly 30% of the available power! MPPT technology used in Microcare MPPT Regulator operates in a very different fashion. The Microcare controller continually tracks the module’s maximum power voltage, in this case 17 volts. It then operates the module at its maximum power voltage to extract maximum power. This provides a 30% increase in power over a conventional charge regulator.

 
 

 

 
 

The higher power extracted from the module is then provided to the battery in the form of increased charge current. This enables the maximum cost per watt to be obtained which creates an economically viable solution on a lower income scale. Each Solar Panel system sold needs a Microcare 20 amp MPPT Regulator to maximize the panel’s power. Manufactured in South Africa.
