The energy autonomy of a house is no longer limited to the installation of a few solar panels. With the growth of renewable technologies and the desire to reduce dependence on the grid, more and more homeowners are turning to creating home microgrids. These systems aim to produce, store and manage energy locally, by combining solar panels, wind turbines, batteries and emergency generators. The objective? Ensure a stable and continuous power supply, even in the event of a long outage in the main electrical network.
Key components for a 100% autonomous home
To achieve this level of autonomy, several elements must be integrated harmoniously:
- High performance solar panels : well calibrated according to exposure and needs, they cover most of the electricity demand.
- Domestic micro wind turbines : they compensate for solar irregularity, especially in winter or during cloudy periods.
- LiFePO4 or li-ion batteries : they store excess production and guarantee a continuous supply during off-peak phases (night, absence of wind).
- Smart hybrid inverter : it manages flows between panels, generators and batteries, while monitoring needs and optimizing the load.
- Standby generator : typically operating on propane or natural gas, it takes over in the event of prolonged failure of other sources.
This architecture guarantees complete electrical coverage, without excessive use of generators, while remaining autonomous and resilient.
Tangible benefits of a home microgrid
Adopting a domestic electrical microgrid has several concrete benefits:
- Energy security : in the event of a generalized outage, your home remains functional, ensuring the comfort, safety of the occupants and the preservation of food.
- Proactive cost management : by combining renewable sources, storage and intelligent consumption control, you greatly reduce or even eliminate your electricity bills.
- Flexibility and scalability : the system can be sized according to your needs and can be easily expanded (adding panels, batteries...). An undeniable advantage for families or future uses (EV charging station, workshop, etc.).
- Resilience and sustainability : by using local and renewable energies, you limit the carbon footprint while protecting yourself against market fluctuations.
Implementation by ERCO: from project to reality
ERCO is distinguished by its global approach:
- Custom analysis : detailed study of your consumption, your roof, ventilation, wind and sunshine.
- Optimal sizing : selection and sizing of panels, batteries and micro-wind turbines according to your specificities.
- Integrated installation : assembly, connection with the hybrid inverter, integration of the emergency generator, tests and commissioning.
- Smart tracking : real-time performance monitoring via a dedicated interface, alerts, proactive assistance.
- Regular maintenance : checking the solar modules, the wind turbine, cleaning, checking the batteries and updating the inverter.
With this approach, ERCO guarantees not only sustainable electrical autonomy, but also optimized performance, season after season.
In summary
Moving to a truly autonomous home means going beyond the elementary solar approach to adopting a home microgrid powered by solar energy, wind, smart storage, and a backup generator. This strategy ensures not only efficient production, but also unparalleled safety and flexibility.
