We compare five batteries: Tesla Powerwall 3, Fox ESS, Duracell Dura5, PylonTech US5000 and Sungrow SBR. Each has different strengths. Tesla Powerwall 3 includes an integrated DC inverter and Storm Watch, making it ideal for new solar installs and properties in storm-prone areas. Fox ESS is AC-coupled and typically cheaper if you already have solar panels. PylonTech is modular, so you can start small and add capacity later. Duracell offers a familiar brand at a lower entry cost. Sungrow is a strong all-rounder for solar-plus-storage.

Your quote shows capacity in kWh, warranty length (typically 10-12 years depending on the battery), inverter type, backup capability, Storm Watch availability and total installed cost. All quotes include 0% VAT applied automatically until March 2027. Interest-free credit available, subject to status.

We do not quote generic prices without surveying your property first. Every home is different: your consumer unit, cable runs, mounting location and existing solar setup all affect what is possible and what it costs. That is why we arrange a no-obligation survey before providing a written quote.

If you are installing new solar, Tesla Powerwall 3 is typically the best total value because its integrated DC inverter means no separate inverter cost. It also includes Storm Watch, which monitors Met Office severe weather warnings and pre-charges the battery before a storm arrives. For properties in the Highlands, islands and exposed coastal areas, this is a compelling feature no other UK home battery offers.

If you already have a working solar inverter and want to add storage, Fox ESS is AC-coupled and typically cheaper for retrofits. PylonTech US5000 is modular: you can start with one 4.8kWh module and add more later as your budget allows. Duracell Dura5 offers a 10kWh capacity at a lower entry cost. Sungrow SBR is a strong all-rounder for combined solar-plus-storage systems.

All five batteries use LFP chemistry, which is cold-rated for Scottish winters and typically lasts 10-12 years under warranty. We install through MCS-certified partners. We are independent and not affiliated with or endorsed by Tesla, Inc. or any battery manufacturer.
