Protect your investment beyond the first 2 years. Up to 5 years of total coverage.
All Silla products are covered by a 2-year legal warranty. With the Warranty Extension, you can extend this coverage by an additional 12, 24, or 36 months, reaching up to 5 years of total protection on your wallbox.
A wallbox is a long-lasting installation that works every day, often outdoors, under all kinds of conditions. Having extended coverage means not having to face unexpected repair or replacement costs during a period when EV technology is still evolving rapidly.
What the extension covers: Coverage is the same as the standard warranty — repair or replacement of the product in the event of manufacturing or material defects, under the same exclusion conditions set out in the terms of sale (it doesn’t cover damage from improper use, non-compliant installation, or external events).
Please note: it must be purchased together with the wallbox. The warranty extension is only valid if purchased at the same time as a Prism range product (any variant) or Homer, in the same order. It cannot be purchased at a later time.
Compatibility: with the Prism range (all variants) and Homer. Not applicable to Silla accessories.

FAQ
Can I purchase the warranty extension after I’ve already bought the wallbox?
No. The warranty extension must be purchased in the same order as the wallbox. It cannot be added at a later time. If you’re purchasing Prism Basic or Prism Solar, now is the right time to consider it.
Does it apply to all Prism models?
Yes, to all variants of Prism and Homer. It is not applicable to Silla accessories.
If I buy two wallboxes, do I need to buy two extensions?
Yes. Each extension is valid for a single wallbox. If you buy two Prism Solar units, you’ll need to purchase two warranty extensions to cover both.
What happens if my wallbox breaks down during the extension period?
Same procedure as the standard warranty: open a request via Silla Support (https://silla.industries/centro-assistenza/), describe the problem, and attach proof of purchase. Silla will assess whether the defect falls within the coverage and will proceed with repair or replacement.
Does the extension also cover damage caused by lightning or power surges?
No. Like the standard legal warranty, the extension doesn’t cover damage caused by external sources such as power surges, lightning, vandalism, or extreme weather conditions. It only covers manufacturing and material defects.
