Prerequisites
Before turning on the AC switch between the BRE-I-5K14K and the power grid, check
that the AC voltage on the power grid side of the AC switch is within the specified range.
⚫
If the DC is on and the AC is off, the BRE-I-5K14K reports a Grid Failure alarm.
The BRE-I-5K14K can only operate after the fault is rectified.
⚫
The BRE-I-5K14K will automatic recover when it detects the grid recovered. When
the AC is off, the BRE-I-5K14K will shut off from the grid and provide power to
EPS load automatically.

properly in grid-tied mode.
If the DC switch is not turned on within 1 minute, the BRE-I-5K14K will enter
the nighttime grid-tied mode. Then, after the DC switch is turned on, the BRE-I-
5K14K will shut down and then restart to run in grid-tied mode.
