Agro-industrial solar installation at Joule Junction — C&I energy infrastructure context

Open DC Platform

The electrical architecture for commercial & industrial power

Joule Junction is building the open DC platform for commercial and industrial energy — one DC backbone, IEEE 2030.5-native metering, and software that optimizes every source and load on site.

Why now

Why 800V DC, why now

Three macro shifts converging on commercial and industrial electrical infrastructure — demanding a rethink beyond incremental equipment on an AC-first spine.

01

Electrification

Fleets, heat, industrial processes moving from fuel to electricity. Every new load needs infrastructure.

02

AI load growth

GPU racks at 400 kW–1 MW make 54V distribution physically non-viable. 800V DC is the only path.

03

Grid congestion

Connection queues stretching years. The bottleneck is distribution, not generation.

Architecture

Systems, not a product catalogue

Energy flows first — grid edge, conversion, shared DC bus, connected loads — before any SKU. Products plug into this graph; they are not the graph.

One open DC spine so generation, storage, charging, and industrial loads share power and data without rebuilding the electrical architecture for every new load.

Design-target architecture — open standards intent, not a certification claim for every SKU.

Commercial outcomes

Architecture that supports buyer goals

Each objective maps to platform composition — not a single box.

Standards

Designed around open standards

Not a certification claim — open-standards architecture for utility-ready interoperability, DER markets, and charging protocols.

IEEE 2030.5

Smart energy profile — DER, BTM, demand response, VPP. Native, not bridged.

OCPP 2.0.1 / 2.1

EV charging communication + metering.

ISO 15118-2 / -20

V2X — V2G, V2H, V2L, V2B — all DC output voltages.

IEC 62443

Cybersecurity — secure comms, certificate management, remote updates, identity management.
