Which Smart PRO is current?

Indra’s current user guide lists exactly two socketed codes: white SPRFGSKWG406 and black SPRFGSKBG420. Older warranty documents also contain installed-base tethered and earlier socketed codes; they should not be mixed into this current page or used as price matches. A separate Type 2 lead is needed. Current user guide.

Check the published ingress rating

Indra’s July 2026 support sheet says IP54, while its current Smart PRO sales page says IP65. The documents also differ slightly on dimensions. This page uses the support sheet’s dimensions and flags the ingress disagreement; ask Indra or the installer to confirm the rating for the exact supplied code before an exposed installation. Support sheet; current product page.

Tariffs and solar

The current guide names Intelligent Octopus Go and OVO Charge Anytime as integrations, and describes solar matching above 1.4 kW of surplus. Check supplier, vehicle and account eligibility for a specific tariff; the charger also supports ordinary app schedules. Indra lists house-fuse load limiting, remote lock, boost and charging history. Current user guide.

Price and warranty

The table shows one independently verified supplier price for the exact white socketed code, VAT included. It excludes the separate vehicle lead, delivery and installation, and it is not a market-wide price ranking. Indra’s code-specific warranty table gives both current codes three years. Return to the Indra range or compare Smart LUX.
