Can I Use a Battery With Plug-in Solar?
Not under the new solar-only plug-in route unless future official evidence explicitly covers the exact configuration.
Battery storage can still be useful, but the correct connection route depends on whether it is portable, off-grid or fixed into the home.

Three battery routes
Portable stations power appliances from their own outlets. Off-grid batteries serve an independent system. Fixed batteries interact with household wiring through professional design.
- Portable: simplest temporary loads
- Off-grid: component design and protection
- Fixed home battery: professional installation
- Plug-in household battery: outside the new route
Battery-integrated solar products
Do not assume a European battery-integrated balcony system is covered. Exact UK official evidence would be needed.
