The SolarEdge warranty extension: how it works and when to sell it
SolarEdge inverters carry 12 years as standard with nothing to register. The extension to 20 or 25 years has to be bought within 24 months of shipment, which makes it the only clock on the brand and a conversation that belongs at handover.

SolarEdge's standard inverter warranty is 12 years and needs no registration. Cover starts at the earlier of installation or four months from shipment. If the customer wants 20 or 25 years, the paid extension has to be bought within 24 months of shipment. That purchase window is the only deadline on the brand, and it is the reason the extension is a handover conversation rather than a later one.
The standard term needs nothing
This is worth saying first because it is the opposite of what installers expect.
SolarEdge gives 12 years on the HD Wave and Home Hub lines with no registration requirement. The commissioning app registers the unit itself. There is no form to submit, no portal deadline, and no condition that has to stay true for the term to hold.
Cover starts at the earlier of installation or four months from shipment. That is the one thing worth recording carefully, because it is not necessarily the install date. A unit that shipped in January and went in during July started its term in May, and you have burned two months of the customer's cover in the warehouse. The warranty deadline calculator works out which date applies from the two you have.
Labour is a separate matter. The HD Wave and Home Hub lines carry 12 years of parts cover and no labour cover at all, which means every visit after the fault is diagnosed is yours to fund. That is normal across the catalogue and it is the number that should shape your service pricing. Work out what a visit costs you with the truck roll calculator.
The one clock: 24 months from shipment
The extension to 20 or 25 years has to be purchased within 24 months of shipment.
Read the anchor carefully. It is 24 months from shipment, not from installation and not from the date the homeowner started thinking about it. On a unit that sat at the distributor for four months, the customer has 20 months from install, not 24. On stock that sat longer, less again.
That single detail is what turns this from a leisurely decision into a dated one. It is also the reason it gets missed: nothing about a two year window feels urgent at handover, and by the time it does feel urgent the window has usually closed.
There is a second reason it gets missed, and it is structural. SolarEdge is one of the brands where a commissioning app handles registration automatically, so your team learns there is nothing to do on this brand. That habit is correct for the standard term and wrong for the extension. Nothing on the site or in the app prompts anyone.

Why this is a sales conversation, not an admin one
An extension is a product the homeowner buys, so somebody has to offer it to them. If nobody raises it, it does not happen.
The best moment is handover, for three reasons.
The window is longest. Every week after commissioning is a week off a clock that started at shipment.
The value is easiest to explain. You are standing in front of the system, the customer has just paid for it, and the difference between 12 years and 25 years on the one component most likely to need replacing is a sentence.
You are still in contact. Eighteen months later you are a company they used once. Reaching them costs a phone call nobody wants to make, and the conversation starts with a deadline they did not know about.
If you would rather not sell it at handover, the fallback is a deliberate second touch: a scheduled contact well inside the window, on a list somebody owns. What does not work is intending to do it and having no record of which installs are inside the window.
When it is worth selling
Frame this the way you would frame any warranty arithmetic, with your own numbers rather than a rule of thumb.
For the homeowner, the question is the cost of an out-of-warranty inverter replacement in year fifteen, weighted by the chance of needing one, against the extension price today. You know the replacement cost better than they do, so you are the one who can put a real figure on it.
For you, there are two effects worth naming.
The first is service exposure. Once the inverter is out of warranty, every failure becomes a quote rather than a claim, and a quote to a customer who believes their solar was meant to last 25 years is an uncomfortable conversation whether or not you were right. An extended term keeps those conversations in claim territory.
The second is that labour still is not covered. Extending the parts term to 20 or 25 years does not make the visits free. It moves the parts cost off your customer, which is real, but the truck roll is still yours in year eighteen exactly as it was in year eight. Do not let the extension talk your service pricing into optimism.
Where it is an easier sell: hard-to-access installs, systems with a battery where a replacement means more than swapping a box on a wall, customers who intend to stay in the house, and any job where the homeowner is already buying on the longest-warranty argument.
Where it is a harder sell: properties likely to change hands soon, and customers who bought on price. Both are legitimate answers. The point is that the customer got asked.
How this compares to the rest of the catalogue
SolarEdge's structure is unusually clean, and the comparison is instructive.
| Brand | The clock, if any |
|---|---|
| SolarEdge | 24 months from shipment, on the paid extension only. Standard 12 years needs nothing |
| Alpha ESS | 30 days from installation, on the paid extension to 10 years. Standard cover is 5 years |
| SMA | No dated deadline. Extensions can be bought any time during the 10 year factory term, up to 20 years total |
| Fronius | 30 months from delivery ex works, for the free 10 year Warranty Plus |
| Silfab | 180 days from purchase, and missing it costs 13 years of product cover |
SolarEdge and Alpha ESS both put the clock on a purchase decision rather than on the warranty itself, which is the friendlier version: miss it and the customer keeps the standard term, they just do not get the longer one. Alpha ESS is the harsher of the two at 30 days from installation, which really only works as a handover conversation.
SMA shows the alternative design. No dated deadline on the extension at all, purchasable at any point during the factory term. That removes the urgency and replaces it with the risk that nobody ever gets round to it, which is the same problem REC's ProTrust has with no published registration deadline.
There is more on that pattern in warranties are conditions, not deadlines.
Running it as a process
Three things make the extension actually get sold rather than intended.
- Record the shipment date, not just the install date. The window and the start of cover both hang off shipment. If your record only has the install date, you cannot tell how much window is left.
- Put the decision at handover, with a fallback contact inside the window. One conversation, and one list of installs where the answer was "not now".
- Log the answer either way. A customer who declined is a closed item. A customer nobody asked is an open one, and the difference only exists if somebody wrote it down.
That is what Claim Timer is for: one record per piece of equipment, the shipment and install dates against it, and the brand's own conditions and windows tracked so an open item stays visible. It does not file with the manufacturer for you, and cost reporting across a quarter is not built yet.
Our SolarEdge entry was read against SolarEdge's Australian warranty pages on 30 July 2026. Terms differ by market and by distributor deal, so confirm the current document for the model you installed before you quote anything to a customer. The SolarEdge registration page has the fields, the claim page has the evidence list, and the inverter warranty comparison puts it next to the other brands.
Checked against
Warranty terms change and differ by country. Treat this as a starting point and check the manufacturer's current document before you rely on it.

Taking on orphaned solar customers when another installer closes
When a solar company closes, its customers keep their manufacturer warranties and lose their workmanship cover. That is a service pipeline, but only if you check which manufacturer conditions are still intact before you take the job.
OperationsSilfab's 180 day window is the most expensive deadline in US residential solar
Silfab's product warranty is 12 years from delivery, or 25 years if the install is registered through Silfab's portal within 180 days of purchase. Performance runs 30 years either way. Missing the window costs 13 years of product cover.
Keep the serial, the photo and the date on every install
Claim Timer stores one record per piece of equipment, with the nameplate photo and the registration confirmation on it, so the claim has its proof already.
