The work is devoted to the development of a model and method for calculating a backup photovoltaic (BPV) system designed to maintain a consumer load under the power grid. The proposed method and algorithm are based on the energy balance equations in the system during the day for given daily profiles of load and outage scenario.  The method allows calculate the sizing parameters of BPV: the power of PV array Pinst and the capacity of batteries Qinst. As an example, various outage scenarios were simulated for BPV located in the Kyiv region, which provides support for a daily load of 10 kW. As a result of simulation the dependences of sizing parameters on the outages characteristics were obtained. The proposed method for sizing problem solving can be used in the design of local backup power supply systems for residential buildings or small businesses in a military situation. The reliability of the backup power supply is estimated when the energy balance is disturbed due to unplanned consumers power outages.
