A Study of MPPT Charge Controller Roles in Photovoltaic Energy Management

Abstract

Nowadays, the world's demand the energy is increasing. So, we need a good energy management system to use the available energy. An energy management system consists of maximum power point tracking (MPPT) charge controller, battery management, and the power conversion stage to control and reduce energy consumption. Solar energy is used solar radiation and is converted into electrical energy. In photovoltaic (PV) system consists of a PV module, charge controller, battery storage, and load. Arduino NANO is used in this project because it's low cost and has an efficient microcontroller in the MPPT charge controller to prevent the battery from overcharging and display the maximum power point (MPP). Perturb and Observe (P&O) and Incremental Conductance (InC) algorithm is used in the MPPT charge controller to transfer maximum power from the PV module which is executed using a microcontroller. The voltage, current, and power from the MPPT charge controller, are shown on a liquid crystal display (LCD). The benefit of this project is to achieve high efficiency and low cost of photovoltaic modules for the design of photovoltaic systems with a simple MPPT.
