Modification and testing of the microinverter development kit for the purpose of connecting the battery system

Abstract

This paper presents the testing of the modified TMDSSOLARUINVKIT solar microinverter development kit manufactured by Texas Instruments. The microinverter consists of two linked converters, one connected to the photovoltaic panel and one to the electrical grid. It is intended for connecting low-power photovoltaic panels to the electrical grid. This paper describes hardware (HW) and software (SW) modifications that were necessary in order to connect the battery system to the platform. In addition to necessary HW and SW modifications, a supervisory control and data acquisition (SCADA) graphical user interface was designed for process control and monitoring. Experimental results demonstrating the possibilities of the modified platform are reported in the paper.
