Overview

What we ship.

We ship a buildable spec, an HMI dashboard, a sensor for transmission lines. Solutions for speed to power.

EDP / Engineering Delivery Package
The buildable spec.

Auto-generated drawings, BOM, and installation sequence. Your integrator builds from this.

EMS / Site Controller
The HMI dashboard.

Runs the plant once it's built. Supervises BESS, compute, and grid. Dispatches against curtailment and price.

DLR / Grid-Edge Sensing
The line sensor.

IEEE 738 dynamic line rating. Surfaces 10–30% of interconnect capacity that static ratings hide.

Solution 01

ARCNODE EDP

Engineering package built from your site constraints. BOM, interface plate DXFs, single-line + P&ID, cable schedule, install sequence. Your integrator builds from this.

01 / BOM
Bill of Materials

Equipment list with vendor, model, quantity, and procurement notes. Fab tier flagged for NDAA and ITAR requirements.

02 / DXF
Interface Plate Drawings

DXF drawings of container interface plates — mechanical mount points and penetrations for power, signal, and cooling connections. Files are ready for fabrication.

03 / DWG
SLD + P&ID + Comms

Single line diagram, piping & instrumentation diagram, and comms architecture drawing — switches, VLANs, EMS data paths to BESS, compute, and grid equipment.

04 / SCHED
Cable & Hose Schedule

Routing, sizing, and termination details. Covers power, signal, and cooling connections between containers and customer-supplied equipment.

05 / SEQ
Installation Sequence

Step-by-step installation and commissioning sequence. Integrator follows it. ARCNODE EMS validates each step before going live.

Solution 01 / What gets built

From the spec to your pad.

Two 10ft ISO containers your integrator builds from the EDP. Compute holds the GPUs and cooling. Grid is optional — switchgear and transformer for utility interconnect. Plugs into your existing BESS and power infrastructure.

Compute Container

Up to 7 HGX B200 nodes with fully integrated direct liquid cooling, networking, power distribution, and ARCNODE EMS — in one 10ft high-cube ISO container. Built from the ARCNODE EDP by your integrator.

GPU CONFIGHGX B200 · up to 56 GPUs
PEAK DRAW~80kW max / container
COOLINGDirect liquid · 210kW CDU integrated
ENCLOSURE10ft high-cube ISO
Grid Container

Optional. Switchgear, step-up transformer, protective relaying, and grid metering for utility interconnect. Required for DC-coupled BESS deployments. May be unnecessary for AC-coupled profiles as integrated substation BESS products emerge.

TOPOLOGYSwitchgear + transformer + relaying
VOLTAGE480V LV / 4.16–13.8kV MV
BESS PROFILESAC-coupled · DC-coupled
Solution 01 / Inside the Delivery Portal

One link. Every artifact.

When your configuration generates, your integrator gets a single signed URL to a dashboard like this. Three columns — system images, engineering drawings, manifests & schedules. Every artifact versioned, every URL pre-signed and 7-day expiring. No login portal to chase.

ARCNODE Delivery Portal — system images, engineering drawings, manifests ARCNODE Delivery Portal on mobile — system images, engineering drawings, manifests
Solution 02

ARCNODE EMS

Site controller. Supervises BESS, compute, and grid on your pad. Runs on AWS or air-gapped per NERC-CIP.

Grid-Flexible Dispatch

Built for non-firm interconnect — the contract type that gets AI loads online in months, not years. EMS rides curtailment events with BESS and throttles compute to stay within contract.

CONTRACT TYPESNon-firm Contract Demand · Interim NITS · Firm Contract Demand
INPUTSISO LMP · Curtailment commands (DNP3/OpenADR) · Grid frequency · Site PCC metering
BESS PROFILESAC-coupled · DC-coupled · None
Supervisory Control

Supervises OTS and custom equipment via industrial protocols. External setpoint architecture — each device runs autonomously, EMS sets the targets.

PROTOCOLSRedfish · Modbus · DNP3 · BACnet · SNMP · MQTT
PATTERNSupervisory · autonomous local loops
Forecast

ML forecasting service with automatic retraining. Pulls site historicals from TimescaleDB plus major grid market data, surfaces predictions to the operator in the EMS HMI.

DATATimescaleDB · Grid market data
RETRAININGAutomatic
SURFACEPredictions panel in EMS HMI
Analyst Agent

RAG agent over a domain knowledge graph and site data. Analysts ask in natural language. Plotting tools render charts inline.

Inside ARCNODE EMS

Desktop analysis + debugging in the field

Live SLD, live telemetry, live dispatch. Write actions require explicit unlock — operators see what's happening, they don't accidentally change it. Full desktop + mobile support; only mobile depicted below.

Solution 03

Dynamic line rating.

Static line ratings leave 10–30% of transmission capacity unused. Grid-edge sensors measure conductor temperature and ampacity in real time per IEEE 738. Operators dispatch against actual thermal limits, not worst-case assumptions.

TWO VARIANTS / ONE PCB

Per-site climatology picks the SKU. Same carrier board and firmware binary across both — the sensor, cable harness, PV panel, and battery are field-swappable kit components.

DLR-CRN-HW · HIGH-WIND
For ridge, coastal, open-plain sites.

Deploy where less than 15% of the year sees wind under 1 m/s perpendicular. DLR falls back to static rating below the sensor's 1 m/s threshold — the marginal capacity below that is small enough to walk away from.

How It Works

Configure. Receive. Build.

ARCNODE generates your engineering package automatically.

01 / CONFIGURE
Spec your stack

Enter your load requirements, site constraints, and deployment context into the System Configurator. The sizing engine outputs a module configuration in seconds.

02 / RECEIVE
One email

Your inbox gets everything: Delivery Portal link (EDP package — BOM, drawings, installation sequence), EMS deployment link (CloudFormation or ISO for air-gapped), and EMS Android client (iOS not supported).

03 / DEPLOY
Your integrator builds it. The EMS runs it.

Hand the EDP to your integrator. They procure the equipment and assemble the containers. Spin up the ARCNODE EMS. The EMS starts in simulation mode and goes live on commissioning — no ARCNODE involvement required after delivery.

FREE & OPEN SOURCE

ARCNODE is open infrastructure. The engineering templates, EMS software, and sizing engine are freely available. We believe the industry moves faster when the stack is open.
