The problem
Why this matters
Buyer pain first — architecture second. If the problem is not real, the stack is irrelevant.
Connection queues stretching years. Export limits. Demand charges. Transformer upgrade costs.
Buyer jobs
- · Stay within contracted import/export limits
- · Defer or avoid network upgrade capital
- · Peak-shave demand charges with storage + controls
Connection queues stretching years.
Export limits.
Demand charges.
Transformer upgrade costs.
Architecture notes
- · PCS enforces export limits at the grid edge (design target)
- · BESS on the DC bus supplies peaks without raising the connection
- · IEEE 2030.5-native metering supports utility-visible behaviour
Architecture
How Joule Junction addresses it
Deployment scale 250 kW–2 MW. The solution traverses these energy-flow stages on the open DC platform.
Energy-flow path
Platform
Three layers. One stack.
Every solution runs on DC BUS, Metering, and Energy Management — the same open architecture at every scale.
DC BUS
The physical DC backbone. SST, BusWay, PCS, protection, and grid interface in one architecture — current flagship 800 V DC.
- Solid State Transformer (SST)
- DC BusWay
- Power Conversion System (PCS)
Metering
IEEE 2030.5-native data layer. Measurement at every point — grid edge, DC bus, load, charger.
- IEEE 2030.5 Smart Meters
- DC Energy Meters
- Sensors & Data Acquisition
Energy Management
Software that optimizes. The layer customers evaluate first.
- Forecasting
- Tariff optimisation
- Battery optimisation
