AC-connected storage
Battery and inverter exchange energy through a defined AC connection.
EMERGING MARKET TRACKER
Small storage. Big questions.
Track products arriving from the UK and European balcony-storage market without treating a fitted plug as a blanket installation approval.
How Battery Boost verifies dataUK + Europe
Battery Boost / Plug-in Batteries
Balcony PV + battery
PV-first ecosystems established in parts of Europe; UK connection position remains product-specific.
Portable crossover
Portable power hardware can offer home-energy functions without becoming a blanket fixed-installation solution.

Plug-in does not mean regulation-free.
Connection method, protection, earthing, circuit capacity, export behaviour, product standards and manufacturer instructions all matter. Do not improvise a connection or use an extension lead. Seek competent electrical advice for the specific product and installation.
