An assembly for generating and accumulating electric power from photovoltaic panels, with submetering, designed for a block of flats

Abstract

The assembly includes photovoltaic panels (1), each of which has a maximum voltage lower than 120 V DC, microinverters (2), electricity submeters (13), a hybrid converter (8), a battery storage (9) with maximum voltage lower than 120 V DC, a signal line (11) and possibly also electricity submeters (13) and a central electricity submeter (7). The photovoltaic panels (1) as well as, via the internal electrical line, also the electricity submeters (13) and the hybrid converter (8) with the battery storage (9), possibly the central electricity submeter (7) are connected to microinverters (2). The hybrid converter (8) is connected via a signal line (11) to the central distribution electricity meter or the central electricity submeter (7). The DC voltage shall not reach 120 V between any two points of the assembly.
