About the project

Installation of an 8kWh battery system in a rural farmhouse in Pontós. The main goal was full energy autonomy, without being connected to the electricity grid. The system complements the existing 10kWp solar installation and covers 100% of the family's annual consumption. The work involved connecting the solar installation — including a Fronius inverter — with the Victron battery charger (with BYD batteries) so both work together in an off-grid setup.
