How to register plug-in solar

What network registration is for, what details to keep and where uncertainty needs checking.

The short answer

A qualifying plug-in device must be notified through the applicable network process. Keep the exact product, inverter and installation details rather than treating registration as proof that any kit is suitable.

Registration and product evidence do different jobs

Network notification records the generation connected at a property. Product evidence shows whether the complete device meets the route’s technical requirements. One does not replace the other.

Have the exact details ready

  • Property and electricity supply details.
  • The complete product and inverter model.
  • Rated AC output and any existing generation.
  • The installation and connection date.
  • A copy of the submitted confirmation.

If you already have solar or storage

Do not treat the new device in isolation. Existing generation, storage controls and aggregate capacity can change the network route. Ask the original installer or DNO when the combination is unclear.
