how can Hi, through which variable I could get output the data for power grid in the building? also I define PV panels and battery for the building is it supposed to be an off-grid or on-grid since the amount of electricity transferred by the power generator energy comes from the grid?utilities are zero?

Hi, through is it possible in energyplus to transfer electricity from building which variable I could get has off-grid system to the data for power grid in the building? also grid? how can I define PV panels and battery for the building is it supposed to be an off-grid that in energy plus? with transformer or on-grid since the amount of energy comes from utilities are zero?other parameter?

is it possible in energyplus to transfer electricity from building which has off-grid system to the power grid? how can I define that in energy plus? with transformer or other parameter?
