| Abstract | In this work a low voltage direct current (DC) distribution system for a house or an apartment have been investigated. The feasibility of the low voltage DC systems for a home is investigated by evaluating the advantages and disadvantages with respect to the existing alternating current (AC) system of homes. The goal is to make a energy efficient system that would be able to cope with local electricity generation and storage systems at the end-user level, from DC sources. Data obtained from measurements of power consumption for different household appliances such as refrigerator, microwave oven, rice cooker, dish washer etc. have been used to evaluating the systems. The performance of the 230V AC system and the proposed low voltage DC system is analyzed by considering factors such as losses in the wire, internal loss of the device itself, investment cost for new wiring and energy consumption cost. From the investigation, it can be concluded that the 48 V DC system with optimized cable area is most economical system compared with the 230 V AC system and with a 20 years life time, it will save almost 13000 SEK.
