3. Introduction
3.1 Basic features
The BRE-I-5K hybrid inverters apply to PV energy storage system with PV module,
battery, loads and grid.
The energy produced by PV system shall be used to optimize self-consumption,
excess power charge battery and the rest power could be fed into the grid. Battery
shall be discharged to support loads when PV power is insufficient to meet self-
consumption. If both PV power and battery power is insufficient, the system will
take power from grid to support loads.
