 (Abstract)
As fossil fuels become depleted and environmental problems arise, the renewable energy is being proposed as a solution to these problems. Among the renewable energy sources, photovoltaic is attracting much attention as an infinite energy source. In order to expand the PV-based infrastructure, the increase in facility supply has not been large due to economical reasons, As the unit price has been lowering and it is expected to be continued to decline in the future, the spread of solar power generation is expected to expand. In this expectation, the PV-related household ESS field is also a hot issue. The household battery pack usually has a voltage of 380 ~ 550V. When the system is constructed by replacing it with 48V, which is relatively low voltage, some features and advantages. In this paper, we discuss the low-voltage system and simulate using the PSIM to verify the validity of the applied system according to the characteristics of the proposed system. And Proto-type has made for experiment and has proved the validity of the proposed system.
