The invention relates to an electrical unit (4) comprising an input having a positive input connection (5) and a negative input connection (6), a boost converter (8), and an inverter (12) having a positive input (25) and a negative input (26), wherein a positive potential is built at the positive input (25) of the inverter (12) compared to the ground potential, and a negative potential is built at the negative input (26) of the inverter (12) compared to the ground potential, during operation, and wherein a substantially potential loss-free connection (7) exists between the positive input connection (5) and the positive input (25) of the inverter (12), and wherein the boost converter (8) is arranged between the negative input connection (6) and the negative input (26) of the inverter (12). The goal is to create an inverter (4) without transformer and without negative potential on the solar cell connections (22, 23), such that said inverter can be used with thin-film panels and particularly with thin-film panels of the superstrate configuration, without causing increased or extended corrosion damages. |
