This bachelor thesis is focused on a project and realization of uninterruptible power supply with the solar panel. The whole system will be instrumental towards supplying gauging radar station without any other possibility to get more electrical energy from the grid (230V). The most important argument for the project is the project is the effectiveness of sthe systems which should prevent losses in the network and unusing energy supplying by the panel. The aim of work is to create a scheme of a suitable leading storage battery type which will be used for saving energy made by the panel. Last but not least is to present the properties of storage battery to prevent wrong manipulating which could cause an effective life reduction or its total ...
