ABSTRACT
In this paper, the emergency power function with high efficiency, high reliability
3kw power, we propose a smart home energy server systems. When the proposed
Systems are Li-Ion batteries charge and discharge bi-directional converter for solar power
Consists of a one-way converter, two-way grid-connected inverter, presenting the operation mode of the proposed system and of the  prototype power 3kW Test validity was verified through.
