    Detailed Applications and Use Cases

    chevron_right Self-consumption optimisation in battery-limited systems
    • Quantifies in real time the available solar energy the array could deliver.
    • Allows redirecting surplus to additional loads (water heating, HVAC, EV charging) when batteries are fully charged.
    • Reduces reliance on later battery discharges by maximising instantaneous use of generation.
    chevron_right Smart management of discretionary loads
    • Provides GX devices and Node-RED with the instantaneous PV power available.
    • Enables optional loads to be switched on or off based on objective real-irradiance criteria.
    • Compatible with energy-management automations and custom dashboards.
    chevron_right Pre-installation site survey and configuration benchmarking
    • Deploy as a pilot device for days or weeks at the customer's site.
    • Quantitative comparison between different orientations, tilts and roof areas.
    • Seasonal validation of the future installation's viability before signing the project.
    • Reinforces the installer's commercial proposal with real on-site data.
    chevron_right Continuous PV array performance audit
    • Cross-checks the inverter's effective generation against the sensor's estimated potential.
    • Detects losses from soiling, partial shading, degradation or orientation drift.
    • Quick diagnostic for technical support and preventive maintenance of the plant.
