How Battery Storage works?

solar panels and battery storage

Battery storage allows you to store electricity generated by solar PV systems or taken from the grid during off-peak hours.

That stored power can then be used when energy prices are higher, during power outages, or at night to maximise efficiency and reducing reliance on your supplier.
Some systems also support “islanding” and off-grid functionality, meaning they can continue to power your property even if the grid goes down, keeping critical systems running and offering true energy security.

Suitable for Every Sector:

    • Domestic Homes
      Lower your electricity bills, use more of your own solar energy, and gain independence from energy price fluctuations.
    • Commercial Buildings
      Reduce peak demand charges, support ESG targets, and improve site resilience with intelligent battery integration.
    • Agricultural Operations
      Pair battery systems with solar or CHP for off-grid capability, backup power, or optimised energy use across demanding rural sites.

Solutions proven to work

We used ESP from recommendation following a couple of failed attempts to get others to quote, one call to Ross at ESP and the ball was rolling. Ross attended site on multiple occasions to asses the site, and offer comprehensive guidance on the best system to use on our site. His staff are all more friendly and helpful, there was a wait on commissioning of the system, and whilst a little frustrating as we were excited to get up and running the time was useful as it allowed us to sort out what we were going to do with our electric meter, is the one we had is unable to measure units to export. ESP also offer A lot of help and advise on sorting this to, we look forward to the saving on return of investment, and would not think twice to use ESP again for any similar projects.

The team were fantastic, From quoting through to order, install & commissioning, they were super responsive, incredibly competent, and nothing was too much trouble.

They put up 22 solar panels, a Tesla Powerwall 3 battery, connected two energy supplies into 1, dug trenches between buildings, installed a Cat6 ethernet cabling system AND kept cost reasonable with no shocks. Above all, they were nice guys! I cannot recommend this company strongly enough.

Dez O'ConnorBiomass Boiler Owner

Superb local company who service our Austrian biomass boiler with expertise and resourcefulness. I’ve been happy to recommend to my friends who also have biomass boilers. I’m very grateful to the ESP team and their knowledge and responsiveness.

Everything you need for Battery Storage

FAQS

Yes. Most modern solar systems are compatible with battery upgrades, and we can retrofit storage to most existing installations.

That depends on your energy usage, solar generation, and goals (backup, savings, off-grid, etc.). We’ll help you choose the right system during your consultation.

Yes, especially when paired with solar PV and/or CHP. We specialise in off-grid and hybrid systems for rural and agricultural sites.

With islanding-enabled systems, your battery will automatically disconnect from the grid and continue to power key circuits in your property.

Most systems are rated for 10–15 years or 6,000+ cycles, depending on the brand and usage. Warranties typically range from 5 to 12 years.
