Maybe someone has been in this situation and can say…
What happens in the situation that one purchases the extended warranty (10 years) and when having a justifiable problem - lets say towards the end of the 10 year period - the product is EOL in that moment?
Depends on the exact product and what the defect is.
A smaller/cheaper device will probably replaced with a newer model, the bigger/expensive devices will be repaired.
Victron will have spare parts in stock for a while to repair old units.
In some cases you will get some money back (not the whole original price) or you get a used/refurbished unit or an offer to buy a new unit for a good price.
