Batteries for continuous energy supply

When our daily lives depend on electricity, ensuring a reliable power supply has become more important than ever. Modern homes require electricity to keep our food fresh, power our remote working equipment and more. Power cuts caused by extreme weather events, electrical grid failures or routine maintenance can disrupt our lives and cause inconvenience or even danger.

This is where home backup energy systems come into play. These systems provide an alternative source of electricity when the main power grid fails, ensuring that essential appliances and devices continue to function during outages. Whether you live in an area prone to natural disasters or simply want to protect yourself against unexpected power cuts, understanding the fundamentals of home backup power is crucial for all homeowners.

Discover the benefits of an electrical backup power system

Protect yourself against power cuts

  • Prevent interruptions to essential equipment.
  • Protect sensitive electronic devices against sudden power outages.
  • Ensure operational continuity in businesses, hospitals and servers.
  • Can reduce energy costs when integrated with renewable sources.

The advantages of a backup system with lithium batteries

The best backup power system

Longer lifespan

  • Last up to 10-15 years or between 4,000 and 10,000 charge and discharge cycles (far superior to lead-acid batteries with 500-1,500 cycles).
  • Less need for replacement, reducing long-term maintenance costs.

High energy efficiency

  • Very low energy loss (95% or higher efficiency in charging and discharging)
  • Less energy waste compared to older technologies.

Rapid recharging

  • Charge up to 5 times faster than lead-acid batteries.
  • Allow more efficient use of solar energy and other charging systems.

Greater depth of discharge

  • Can be discharged up to 90-100% without affecting lifespan. (Lead-acid batteries only allow 50-60% before damage occurs).

Reduced weight and size

  • Lighter and more compact, making installation and mounting easier.
  • Ideal for limited spaces and scalable modular systems.

Low maintenance

  • Don’t require constant checking or liquid refilling like lead-acid batteries.
  • Hermetically sealed and safe, with no toxic gas emissions.

Safe and thermally stable

  • Incorporate Battery Management Systems (BMS) that protect against overcharging, overheating and short circuits.
  • Lower risk of fires or explosions compared to other technologies.

Compatibility with renewable energy

  • Integrate perfectly with photovoltaic systems and allow efficient storage of solar energy.
  • Help reduce dependence on the electrical grid and optimise self-consumption.

Silent operation

  • Unlike diesel generators, lithium batteries emit no noise or vibrations, making them ideal for indoor use and sensitive environments.

Sustainability and lower environmental impact

  • Don’t contain toxic heavy metals like lead or cadmium.
  • Lower carbon footprint compared to other backup energy sources.

Benefits of a backup system in homes

Key points of installing backup batteries in your home

  • 1

    Energy autonomy: maintains electricity during power cuts.

  • 2

    Savings on your electricity bill: when combined with solar panels, allows you to make the most of generated energy.

  • 3

    Automatic transition: in case of a blackout, the system activates in milliseconds without interruptions.

  • 4

    Clean and sustainable energy: using lithium batteries instead of diesel generators.

  • 5

    Low maintenance: doesn’t require constant recharging or regular inspections.

  • 6

    Silent: does not generate noise or vibrations.

FAQ

Frequently asked questions

Yes. The 2026-2027 Balearic grant has a specific line for adding batteries to existing photovoltaic installations, with up to 60 % subsidy.

Between 10 and 15 years, or 4,000 to 10,000 charge and discharge cycles, far more than lead-acid batteries (500-1,500 cycles).

Yes, if the installation includes a backup system. Your home or business then keeps running on the stored energy for as long as the outage lasts.

Without a battery you only use the energy while the sun is shining; with a battery you also use it at night and during outages. With high night-time consumption, or if you want backup, a battery usually pays off.

Practically none. A lithium battery requires no intervention; the periodic system check included in our maintenance service is enough.
