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.

4.3. Determining the Installation Position
Basic Requirements
⚫The BRE-I-5K14K is protected under IP54 and can be installed indoors oroutdoors.
⚫Do not install the BRE-I-5K14K in a place where a person can easily come intocontact
with its enclosure and heatsink, because these parts are scorching duringoperation.
⚫Do not install the BRE-I-5K14K in areas with flammable or explosivematerials.
⚫Do not install the BRE-I-5K14K at a place within children'sreach.
⚫The BRE-I-5K14K will be corroded in salt areas, and the salt corrosion may cause a
fire.Do not install the BRE-I-5K14K outdoors in salt areas. A salt area refers to the
region within 500 meters from the coast or prone to the sea breeze. The region prone to
sea breezevaries depending on weather conditions (such as typhoons and monsoons) or
terrains (suchas dams and hills).
