The main objective design of this off-grid energy system is to meet the desired electric load of the  smaill office  & residential loads with low renewable fraction, low emissions and low cost of energy. The goal is to manage the energy consumption of the building, reduce the associated cost and to switch from grid-tied fossil fuel power system to an off-grid renewable and cleaner power system. Solar setup is a boon for both low electrified rural areas & also for a high consumer base in the urban cities.
