A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A ''stand-alone microgrid'' or ''isolated microgrid'' only operates off-the-grid and cannot be connected to a wider electric power system. [4]Very small microgrids are called nanogrids.
So, for a 16.2 kWh/Day load, the sizing results given by the software are 3.5kW for the PV system and 800Ah/26V for the battery pack. Regarding the power converters, the article (Pérez-Higueras et al. 2018) suggests that the quotient of the rated power of the solar inverter over the peak power of the PV system should be between 0.84 and 1.12.
