12.2.2 MPPTCore module
12.3 Lead-Acid battery charging module
12.4 Sample charge controller and load control application
12.5 Sample applications
This module contains the Maximum PowerPoint Tracking (MPPT) algorithm. This
algorithm continuously tracks the maximum power point of the PV panel and makes the
system to operate at the MPP which ensures the maximum power is generated from the
PV. This module supports the well documented APIs that aid in application programming.
Typical module functionality includes, starting the MPP tracking algorithm,
enabling/disabling the MPP tracking algorithm and retrieving logged parameters from the
MPPTCore module.
This is an optional software library provided along with the MPT612 IC. This module
implements the lead-acid battery charge cycle for 2-stage, 3-stage and 4-stage batteries.
Using the easy configuration for the battery parameters and well documented APIs, the
user can design an application with ease. This module together with the MPT612SW will
help in the creation of power management systems for battery charging for home and
street lighting applications.
This module implements the sample charge controller and load control application for the
specification of the MPT612 reference board. It uses features of the MPT612SW and
lead-acid battery charging module to implement a typical charge controller application.
Using MPT612SW and lead-acid battery charging module, solutions for several
applications can be generated such as:
In the SW architecture diagram shown in
with MPPTCore module to extract the maximum power which can use a micro-inverter, to
feed it to the grid. SampleApplication2 utilizes the services of the battery charging
algorithm to charge the battery and can be used to control different lighting applications.
• dusk-to-dawn lighting applications
• street lighting applications
• traffic lighting applications
• solar based mobile chargers
• DC-DC converters in panels
