Why now

Why 800V DC, why now

Three forces pushing sites past passive AC distribution.

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.

Digital layer

Joule Junction OS

Native IEEE 2030.5 architecture. The digital layer across DC BUS, Metering, and Energy Management.

  • IEEE 2030.5

    Smart energy profile — DER, BTM, demand response, VPP.

  • OCPP 2.0.1 / 2.1

    EV charging communication.

  • ISO 15118-20

    V2X (V2G, V2H, V2L, V2B).

Standards

Designed around open standards

Utility-ready interoperability targets — not certified marks.

IEEE 2030.5

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

CSIP-AUS

Australian smart inverter profile — IEEE 2030.5 implementation for DNSP compliance.

OCPP 2.0.1 / 2.1

EV charging communication + metering.

ISO 15118-2 / -20

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

IEC

Global market compliance.

IEC 62443

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