Deployment of a hybrid power system is expected in places outside the normal distribution network. For the further research and improvements it is necessary to know in detail the power flow from various sources to the load or to storage battery depending on different seasons. The paper presents data analysis results computed by application developed for detailed analysis of power flows within hy- brid power system. Developed application analyses the data from the monitoring system. Data has been acquired and recorded within last year. This data is visualized as power flows in the individual hybrid power system circuits. To- gether with electrical power the effectiveness and performance parameters of rectifier and DC/AC converter are evalu- ated. The paper describes achieved results and needs for further improvements of such solution. Keywords: Hybrid Power Systems; Data Analysis; Application Software 1.
