Product Introduction
BEG1K0110G/1K086U is the bidirectional ACDC power module used to connect the battery or DC bus to the AC grid. It is specially designed for bidirectional applications in battery energy storage systems with multiple battery groups in parallel to achieve safety isolation and fexible capacity expansion. It can also be used in retired battery utilization and AC micro grid applications. By employing the high frequency SiC MOSFET switch technology, it can achieve excellent performance, high power density, high efficiency and high reliability.

BEG1K0110G
*DC side voltage needs t*DC side voltage needs to be higher than the AC peak line voltage + 30V.
For example, the actual AC line voltage is 528V, the module is running in on/off-grid mode, the DC side voltage must be higher than 528*1.414 + 30V = 776.6V.
*The power module can not be connected to the neutral line from the grid side.
In off-grid mode, BEG1K0110G will output the neutral line to load, but the BEG1K086U doesn't support it.
But in the system inner, the power module's neutral line need to be connected together.o be higher than the AC peak line voltage + 30V.
