Abstract
This document introduces the Distributed 48 V Energy Node (D48EN) architecture, a modular approach to home and community-scale energy storage and power distribution. Unlike conventional DC microgrids that rely on a continuous shared bus, this architecture places independent 48 V battery nodes throughout a structure, each with its own point-of-load photovoltaic (PV) input and short-run DC distribution to nearby loads. Nodes are normally isolated electrically and do not form a high-power backbone. Instead, low-current redistribution links allow controlled, schedulable energy sharing between nodes. This configuration reduces wiring cost, improves safety, simplifies retrofits, and enables modular growth for both developed residential homes and developing region community systems, while retaining the ability to support high-power loads at the room or appliance level.
