2 Product Overview
2 Product Overview
2.1.Product Introduction
Function
BRE-I-5K14K is a single-phase grid-connected PV string inverter and energy storage system.
It can store the DC power generated by the PV string into the battery, or convert the DC
power generated by the PV string or the stored energy of the battery into AC power. Power
is input to the grid.
Networking Application
The BRE-I-5K14K applies to a residential rooftop grid-tied system. Typically, a grid-tiedsystem
consists of the PV string, grid-tied inverter, AC switch, and power distribution unit.
