Fronius Energy Cost Assistant (ECA) – AI-Based Energy Management:

The Fronius Energy Cost Assistant automatically supports you as a PV system owner with battery storage to improve your energy use. This allows you to get the most out of your storage system and also save on electricity costs.

It’s an AI-powered tool designed to help homeowners with solar PV systems and battery storage optimise energy usage and reduce electricity costs. The AI technology continuously analyses the expected PV production of your system, your energy consumption and the current electricity price and adapts the storage strategy accordingly.

Key Features:

  • Real-time optimisation using solar forecasts, household consumption data, and electricity market prices.
  • Smart battery charging during low-cost periods
  • Cost savings by reducing reliance on grid electricity.
  • Battery health management to minimise wear and extend system lifespan.

To activate and use the Energy Cost Assistant, the following components are required:

  • A Fronius GEN24 Plus inverter
  • A Fronius Smart Meter
  • Battery storage
