Abstract

Grid-connected photovoltaic (PV) systems, in their classical configuration, do not have battery bank for
energy storage, but how these systems are dependent on climatic conditions, which makes them an intermittent source,
the application of energy storage is an alternative to reduce the variation of power produced and to improve the quality
of energy delivered to the grid. This work proposed the installation of a grid-connected PV system with microinverters.
The system was composed of two arrays, one in the classical configuration and the other one using energy storage. In
addition to the installation of the PV system, a data acquisition was developed to improve the managing of the system.
Each array was composed of one 265 W module and one 240 W microinverter of model SUNNY BOY-240. One of the
arrays had a battery storage operating in the voltage of 24 V, with a nominal capacity of 200 Ah and a MPPT charge
controller. The data acquisition and control unit has been configured for 1 and 10 s measurements. Through analyses, it
was observed that energy storage in the grid- connected photovoltaic systems is very effective, mainly to reduce the
power fluctuation delivered to the grid by the microinverter.
