The UK is finally adopting the highly successful European Balkonkraftwerk (balcony power plant) model, but with a uniquely British technical upgrade. On the continent, DIYers use a standard 2-pin Schuko plug to backfeed their homes. In the UK, our systems utilize a fused 13A 3-pin plug, which provides a safer, higher-rated connection to your household ring main.

Transitioning from Closed-Loop to Grid-Tied Currently, the most accessible way to harness DIY solar in the UK is through a closed-loop system: routing DC power from your panels directly into an off-grid LiFePO4 solar generator. This isolates the power from the National Grid, requiring zero paperwork. However, the regulatory landscape is shifting. The impending BS 7671 Amendment 4 establishes a compliant legal framework to transition these setups into true grid-tied systems.

Once fully enacted, DIYers will be able to connect sub-800W microinverters directly into their wall sockets. By securing standard rigid or flexible PV panels to a shed or balcony and wiring them via standard MC4 connectors, the generated electricity naturally follows the path of least resistance to power your home’s baseload. To remain fully compliant, users simply submit a standard G98 notification to their local DNO (Distribution Network Operator) within 28 days of commissioning, officially registering the micro-generation system with the grid.
