From concept
to closed-loop.

Scope · GCSC

Five custom PCBs integrating industrial protocols and mixed signal types, running a closed-loop controller alongside an operator-facing interface.

System synergy

VirtuHot collectors charge a thermal buffer that feeds the source side of a water-to-water heat pump. A warmer source raises the COP, so the same heat output costs less electricity — compounding two benefits: lower CO₂ emissions and flatter peak loads that reduce grid-congestion risk.

Full-stack delivery

• System architecture: unified logic binding collectors, storage, and heat pumps into one coordinated plant.
• Custom hardware: IoT-capable PCBs handling PWM, analog, Modbus, and SPI on a single board.
• Embedded software: low-level firmware and protocol stacks tuned for reliability, speed, and robustness.
• Advanced controls: feedback loops and real-time optimisation driving continuous efficiency gains.

The problem

Low-voltage grids were never designed for two-way power flows. With rapid connections of solar, EV chargers, and heat pumps, operators lack visibility below the MV/LV transformer and fall back on worst-case assumptions when planning reinforcement.

Scope · GCSC

Custom sensing hardware paired with an edge inference stack running a physics-informed neural network state estimator — enforcing Kirchhoff's laws on-device, without cloud dependency for critical calculations.

Full-stack delivery

• Sensing hardware: Rogowski coils and voltage probes, sampling at 8 kSps with capture up to the 80th harmonic.
• Edge compute: on-device inference — critical calculations run without cloud dependency.
• State estimation: physics-informed neural network enforcing Kirchhoff voltage and current laws.
• Grid integration: IEEE 1588 PTP time sync (±1 µs), IEC 61850 MMS + GOOSE output, 4G/LTE connectivity.
• Dynamic envelopes: real-time Dynamic Operating Envelope computation and sub-Hz oscillation detection (0.2–1 Hz).
