The argument against the idea of off-grid NZEB is that energy storage technologies are not mature enough to serve the function of grid connection to maintain the reliability of power supply. Thus, designers usually propose oversizing the renewable energy sources in order to ensure there is no loss of load due to unpredictable weather condition.
