Open DC Platform
Three layers. One architecture.
Not three products. One stack where every layer reinforces the next — DC BUS for power, Metering for measurement, Energy Management for optimisation. Designed for open standards and utility interoperability.

Why it matters
Systems, not a product catalogue
C&I sites add solar, storage, chargers, and loads one device at a time. Conversion stages multiply and data stays siloed. The platform lets generation, storage, charging, and loads share one DC backbone and one digital layer.
Layers
DC BUS · Metering · Energy Management
Every layer has a clear job. Together they form the open DC platform.

DC BUS
The physical DC backbone. SST, BusWay, PCS, protection, and grid interface in one architecture — current flagship 800 V DC.
Physical 800V backbone — SST, BusWay, PCS, protection, grid interface.
- Solid State Transformer (SST)
- DC BusWay
- Power Conversion System (PCS)
- Protection, controls

Metering
IEEE 2030.5-native data layer. Measurement at every point — grid edge, DC bus, load, charger.
IEEE 2030.5-native measurement at grid edge, bus, load, and charger.
- IEEE 2030.5 Smart Meters
- DC Energy Meters
- Sensors & Data Acquisition
- OCPP 2.0.1 / 2.1 Charging Metering

Energy Management
Software that optimizes. The layer customers evaluate first.
Software that optimizes — forecasting, tariffs, dispatch, VPP.
- Forecasting
- Tariff optimisation
- Battery optimisation
- Solar optimisation
How it works
One energy flow
From grid connection through the DC bus to connected systems and EMS — one architecture, not a pile of standalone devices.
