Qbits Solar Inverter Warranty Documents: What to Get in Writing

Before you accept a Qbits quote, ask for one document: the current written warranty for the exact inverter model printed on that quote. The public datasheet is not that document, and Qbits says so itself.

Short version. Every Qbits product page carries a note stating that the public datasheets describe an expandable warranty but do not define the base term, the remedy, the registration deadline, or the exclusions. Every product record on the site shows “Request current written terms” where a warranty period would normally sit. The support portal that handles warranty requests asks for a 12-digit serial number, so it serves existing owners rather than buyers. That leaves one correct action at the quote stage: obtain the written terms for your exact model, check them against the eleven clauses below, and decide afterwards.

What the public Qbits material does establish

Two things, and they are worth separating from what people assume.

It establishes that the warranty is expandable. The structure allows cover to be extended beyond a base period. That is a real and useful fact about the product family.

It establishes the model scope of the specification, because Qbits publishes per model datasheets. Efficiency, protection features, IP rating and communication options are model specific, and so is warranty cover. A term that applies to one series does not automatically apply to another.

That is the honest extent of it. Everything a claim actually turns on sits outside those documents.

What the public material does not define

The note published on every /our-products/ page is explicit. The public datasheets do not establish:

• the base term, meaning the length of cover before any extension;
• the remedy, meaning what Qbits will actually do when a unit fails;
• the registration deadline, meaning the window in which you must register to keep cover;
• the exclusions, meaning the conditions under which cover does not apply.

Those four gaps are not trivia. They are the entire financial substance of a warranty. A long headline period with a narrow remedy and an early registration deadline is worth less than a shorter period with a clear replacement obligation and no registration trap. This is the general point covered in our guide to solar inverter warranty in India, and it applies to every brand, Qbits included.

Because those four are undefined in public material, this article does not tell you a Qbits warranty period, and you should be careful with any source that does without showing you the document behind it. A number you cannot trace to a dated, model specific document is not a number you can rely on when you need to make a claim.

The warranty request route, and what it does not give a buyer

The Download Warranty link in the site footer points to the Qbits support portal. Checked on 26 September 2026, that portal loads correctly and presents a form that requires a 12-digit serial number before a warranty request can be submitted.

Read that carefully, because it has a practical consequence. A serial number exists on a unit you already own. It does not exist on a quotation. The portal is therefore designed for the claim stage, not the comparison stage, and it does not publish the warranty text, the covered model, the term, the remedy or the exclusions in its public response.

So the portal is the right route once you own an inverter and something has gone wrong. At the quote stage you need a different route: ask the dealer, or ask a Qbits engineer directly, for the current controlled warranty document covering the model you have been quoted.

The eleven clauses to obtain in writing

This is the checklist. Do not accept a summary, a marketing line, or a screenshot of a datasheet table. Ask for the document that contains all eleven, and read them in this order.

Print the reply, save the email it arrived in, and keep both with your invoice and commissioning certificate. Our warranty claim checklist sets out the rest of the evidence file you will want if you ever need to use it.

What most buyers get wrong here

They compare warranty periods across brands as though the number were the product. It is not. The number is the only part of a warranty that is cheap to advertise, which is precisely why it is the part that gets advertised.

A more useful comparison is to line up two written documents and read clauses 4, 5, 7 and 9 side by side. That is where the real difference between two offers usually sits, and it is the comparison our review of the longest inverter warranties in India is built around.

The second common error is assuming one warranty covers the whole rooftop. It does not. The inverter, the modules, the mounting structure and the workmanship are typically covered by different parties under different documents with different lifetimes. Installation warranty and product warranty are separate things, and the gap between them is where a surprising number of disputes live.

If the terms do not arrive

Ask once in writing. Keep the reply, or keep the silence.

If written terms for the exact quoted model still do not arrive, that is itself information about how a future claim is likely to go, and you are entitled to weigh it. Ask the same question of one competing brand and compare what each will commit to on paper. A supplier that produces a dated, model specific document quickly has told you something real about its service posture.

Also confirm who will physically attend a failure. Check whether there is a service partner near your pin code on the authorised service partner list, because the nearest technician, not the printed term, determines how long you sit without generation.

Your next step

If you are holding a Qbits quote, do this in order. Note the exact model code. Request the current written warranty for that code. Check it against the eleven clauses above. Then decide.

To get the document for a model you have been quoted, talk to a Qbits engineer with the model code and your pin code to hand, and ask for the current written warranty terms in the reply.
