Hi
I have two victron products
Quattro 8kva
Mppt 150/100
These was supplied by my original installer in feb2020.
I want to know what warranty there is on these two products ?
Due to my PV array being damaged in hail storm, I have to replace the PV array. The new supplier may have to supply and install a new mppt to 250/100.
How do I validate that the new supplier is in good standing with victron ?
5 year warranty from day of purchase. If no proof of purchase, then 5 years from day of manufacture. Victron knows through what reseller the product was purchased. Perhaps not the exact shop, but they will know who bought it first.
Manufacturing date is on the serial number. It will start with HQ, followed by 4 digits which represent the year, and the week of the year it was made.
There isn’t really such a thing as “good standing”, at least an installer that goes awol or even a reseller that goes out of business does not invalidate the warranty. It is however easier to return something through the same channel that you bought it, but outside that, any Victron shop should be able to help you out with a replacement. Installers “in good standing” will often replace it on the spot and handle the RMA afterwards.
Can this warranty be extended?
I extended by 4.5yo MPII 5kva with another 5 years.
Ask your dealer.
Yes it can be extended from the standard 5 years to 10 years.
Victron started the warranty extentions a while back, I can’t remember exactly when. I’m not sure if they will extend warranties on products bought before that date as well, best to ask your friendly dealer / installer with your serial numbers at hand.
I am assuming it is extension at a cost though? How much is that? Or rather what it was in your cases though it might not be the same for me.
10% added to the price if I remember.
This text is included in the Price list, bottom of second last page:
Warranty to end users:
Li-ion batteries: 3 year limited warranty
Other batteries: 2 year limited warranty
All other products: 5 year limited warranty
All other products: 10% surcharge on actual net price for 5 year warranty extension (10 year warranty)
Warranty extensions need to be applied for ultimately one year before expiration of the original term.
So, an extra 10%. And you have to do it before the equipment is 4 years old.
Sounds fantastic to me. Missing some context - what price list? Probably the document from dealer to reseller?

Oh wow! Never thought this would be public or applicable to SA
