Smart Home Energy 
A serious home battery without the installation costs — stores solar or cheap overnight electricity and replaces expensive grid power when you need it most. The Manual Transfer Switch lets you easily switch between grid power and a portable power station anytime but this setup requires a licensed electrician for the installation. Is easily expandable with 1 or 2 more batteries and EcoFlow offer a bundle with a portable 400w foldable solar panel for £3348
Problem it solves
Large-capacity portable battery for serious grid arbitrage or solar storage. Powers home essentials for hours during outages.
Who it's for
Homeowners or higher-budget renters wanting meaningful arbitrage or solar storage without a fixed installation.
Why we recommend
This is a serious home battery that can also be moved so is useful for remote power solutions too. You'll still need an electrician to wire things up if you want to do real arbitrage but it will cost a lot less than a normal home battery installation.
