Off-Grid: A Battery based Solar Power Plant will supply electricity from Solar Panels . In the day time solar will run the connected load and balance energy storage in the form of a battery bank provides a buffer and control flexibility to allow optimum use of the renewable energy source without jeopardizing the robustness and quality of power delivered to the customer. The system controller will monitor and measure how much energy is being produced by the solar array, it has the ability to harvest the maximum possible energy. In the event of large availability of solar power and less load, it will be possible to store the energy in the battery and to cater the load simultaneously. The battery bank will allow excess solar energy to be stored and used later on when required.In effect the battery bank will provide flexibility and supply.
