Energy storage evaluation under surge load in an off-grid photovoltaic system

This study analyses the performances battery energy storages under surge load condition in an off-grid photovoltaic (PV) system whereby the surge load condition refers to the high start-up current being drawn by the motor load. The main contribution of this paper is determining the performances in t...
