Photovoltaic powered DC voltage network with variable voltage for consumption optimization

摘要

Photovoltaic systems can be used to heat up heat storage. In order to allow amortization within reasonable periods of time, the system must be simple and the energy available must be used as efficiently as possible. The photovoltaic panels and possibly other energy producers feed by means of power optimizers in a DC network with greatly varying voltage. A permanently connected consumer is dimensioned so that it converts the available power at Maimalspannung. Other consumers can be operated on the DC network and divide the available power according to the resulting DC voltage. Domestic hot water heating, heating support, supply of buildings without public network
