Certified Tesla Battery Installers Scotland

Each Tesla Powerwall has a usable capacity of 13.5 kWh (kilowatt-hours) of electricity storage, and it can deliver a continuous 5 kW of power (with peaks up to 7 kW per unit). In practical terms, one Powerwall can run an average home through the night or keep essential appliances running for many hours during an outage. For example, 13.5 kWh could cover basics like your fridge, lights, Wi-Fi, and a few sockets for a day or two in an emergency (actual duration depends on what you’re powering).

For whole-home backup or properties with higher consumption, multiple Powerwalls can be installed together. Up to 10 units can be linked to scale up storage for large homes or businesses​.

During our consultation, we’ll assess your energy usage and recommend the appropriate number of Powerwalls to ensure your critical needs are met. Most Scottish homes find that one or two Powerwall units provide ample coverage for nightly use and typical outages.

If the grid goes down, Tesla Powerwall will automatically disconnect your home from the grid and take over powering your home within a fraction of a second – so fast that your lights and devices won’t even flicker. It’s an instantaneous, seamless switchover. The battery will then supply electricity to your home from its stored energy. Essential appliances stay running: you can keep the heating on, your food fresh in the fridge, and your phones/laptops charged.

If you have solar panels, they will continue generating power during the outage (thanks to the Tesla Backup Gateway), and any excess solar can even recharge the Powerwall while the grid is down. This essentially turns your home into a self-sufficient island until grid power is restored.

Powerwall’s ability to provide backup power gives you great peace of mind, you’re protected from blackouts, which is especially valuable for rural areas or during winter storms in Scotland

A standard Powerwall installation by our team typically takes just one day​. Our installers handle everything, including any necessary electrical upgrades. On the installation day, we will need to turn off your electricity for a few hours (around 4–6 hours) while making the grid connections and testing the system​.

We mount the Powerwall unit on a wall (usually in a garage, utility room, or outside wall), install the small Tesla Gateway box near your main electrical panel, and run the wiring to integrate with your system. We then commission the system and set up your Tesla app. By the end of the day, your Powerwall will be up and running.

We’ll also give you a tutorial on how everything works. It’s a hassle-free process and Jorro takes care of all the technical details, including any permitting or paperwork, so you can start enjoying the benefits immediately.

Tesla Powerwall is designed for long-term performance. The unit comes with a 10-year manufacturer’s warranty​, which guarantees that the battery will retain a high capacity (Tesla warrants at least 70% of its original capacity at 10 years with regular use). In practice, lithium-ion batteries like Powerwall can last well beyond 10 years with proper use. There is no regular maintenance required – the Powerwall is completely sealed and requires no servicing or fuel, unlike a generator​.

Software updates are delivered automatically by Tesla to optimize efficiency and functionality over time.

With Jorro’s installation, we ensure the battery is set up in an ideal environment to maximize its lifespan (for example, proper ventilation if indoors). You can expect many years of reliable operation and we’re always here to support if you have questions down the line. Tesla’s robust warranty and our expert installation mean your investment is secure.

Yes, absolutely. While Powerwall is often associated with homes, it is also an excellent solution for businesses and commercial properties looking to cut energy costs and add backup power. In fact, Tesla designed Powerwall for both residential and light commercial use.

Small offices, retail stores, farms, and other commercial facilities in Scotland can benefit from installing one or several Powerwalls to manage their energy. By storing energy, a business can reduce peak demand charges, run critical equipment during outages, and improve its sustainability profile. Powerwall units can be daisy-chained to provide higher capacity, giving businesses flexibility to scale the storage system to their needs.

Jorro has experience deploying solar and battery systems for commercial clients, and we can design a setup that keeps your operations running and saves you money.

If you have larger energy requirements, we’ll assess whether multiple Powerwall units or a larger commercial battery solution is the best fit. Either way, we’ll ensure your business reaps the rewards of energy storage technology.
