A battery assembly and photovoltaic system

Abstract

The application is suitable for the photovoltaic technical field, and provides a battery assembly and a photovoltaic system.The battery assembly comprises: a first module, the first module comprises three battery string groups connected in series, each battery string group comprises two battery strings connected in parallel, and each battery string comprises a plurality of four-pieces connected in series; a second module, the second module comprises three battery string groups connected in series, each battery string group comprises two battery strings connected in parallel, and each battery string comprises a plurality of four-pieces connected in series; and the first module and the second module are connected in parallel through a connecting module.The independent structure design of the first module and the second module avoids the problem of circuit breakage caused by excessive connecting lines, and improves the reliability and stability of the battery assembly.
