Solar, storage and backup in Viseu: power available even during a grid outage
A 4.4 kWp photovoltaic system with 6.3 kWh of Fronius Reserva storage and a backup system, in a home in Viseu. Premium European equipment (SunPower, Fronius, ESDEC) integrated into a single system to maximise self-consumption and keep power available even during a grid outage.
An excellent photovoltaic installation begins long before the first kilowatt-hour is produced. It begins with engineering, with the careful selection of equipment and the ability to integrate every technology into a single system. In this project, the goal was to develop a highly reliable solution, based on benchmark European technology and ready to keep pace with the home's evolving energy needs.
Energy produced, stored, and available when it matters most.
The owners wanted to reduce their dependence on the grid, increase self-consumption and gain greater energy security in the event of a supply failure. The solution had to combine high performance, intelligent monitoring and storage capacity, while also leaving room for future upgrades.
The challenge
Design an integrated solution bringing together photovoltaic generation, energy storage and a backup system, favouring premium equipment that is fully compatible with each other and able to deliver high performance, reliability and longevity.
- 4,40 kWp installed photovoltaic power
- 6,3 kWh energy storage capacity
Design and installation
Enbiente developed an integrated solution based on benchmark European technology, sized to maximise self-consumption, increase energy autonomy and ensure greater continuity of service.
- A photovoltaic system of 10 SunPower 440 W panels
- ESDEC FlatFix Fusion mounting structure for a flat roof
- A Fronius Symo GEN24 4.0 Plus hybrid inverter
- A Fronius Reserva storage system of two 3.15 kWh modules (6.3 kWh)
- A Fronius Smart Meter TS 100A-1 for intelligent monitoring and consumption management
- A Fronius Backup system to power essential loads during a grid outage
The result
The home now benefits from a more autonomous, efficient and resilient energy infrastructure, able to produce, store and manage energy intelligently. The integration of every piece of equipment optimises self-consumption, reduces dependence on the grid and brings greater peace of mind in the face of supply interruptions. More than a photovoltaic installation, this project shows the importance of integrated engineering, where each component is selected to work as part of a single system, ready to evolve and keep pace with the home's future needs.
