DISCOM Approval for Solar Inverters: How to Verify Your Model

There is no national list of DISCOM approved solar inverters in India, and any quotation that implies otherwise is worth a second look. Acceptance is decided by the distribution utility that will connect your system, against its own current document, for your exact inverter model.

Why no single national list exists

Under the Indian constitutional split, electricity is a concurrent subject and distribution sits with the states. Each state has its own electricity regulatory commission, and each DISCOM operates its own network with its own conditions for connecting generation to it.

That produces a regime with a predictable shape. National bodies set standards and scheme rules. State regulators decide whether and how net metering is offered. The DISCOM decides what it will physically connect to its network, and it documents that in equipment lists, technical circulars and interconnection rules that it revises on its own schedule.

The practical result is that “DISCOM approved” is not one status. It is a statement about one utility, at one point in time, for one model. MSEDCL, TANGEDCO, BESCOM and Torrent are four different decision makers, and a list from one is not evidence for another.

This also means a national best of list of approved inverters cannot honestly be written. Ranking models by an approval that varies by jurisdiction, scheme and document revision would imply a status none of them uniformly hold.

What ALMM does and does not cover

This is the single most common confusion in Indian rooftop quotations, so it is worth stating plainly.

MNRE’s Approved List of Models and Manufacturers publishes List-I for solar PV modules and List-II for solar PV cells. Those lists govern module and cell sourcing. Neither of them tells you whether a given inverter model will be accepted for your connection.

Verify the module and cell position against the current MNRE ALMM pages, and verify inverter acceptance separately against your DISCOM. The positions are checked as of September 2026 and both can change, so confirm the current documents rather than relying on this article or on a quotation footnote.

Certification works the same way. A conformity mark records that a model met a named standard when it was tested. Your DISCOM may still require particular protection functions, a specific test report, a current certificate revision, or presence on its own list. Certification is evidence you will be asked for, not the decision.

What actually decides whether your inverter is accepted

Five layers, and they are decided by different bodies at different times.

Nothing in the upper rows guarantees the bottom row. A model can satisfy every standard in the country and still be refused on a specific feeder for a reason that has nothing to do with the product.

The verification sequence, before you pay

Run these six steps in order. They take a few days and they sit entirely before your equipment instalment.

1. Write down the exact model code. Not the brand, not the capacity, not the series. The full model identifier as it appears on the datasheet, because acceptance decisions are made at that level.
2. Identify your DISCOM by name and your division. Your electricity bill carries both. Acceptance is a property of that utility, not of your state in general.
3. Obtain the current controlling document. Ask the DISCOM, or your installer, for the current equipment list, technical circular or interconnection rule that applies to rooftop net metering in your division. Note its issuing body and its effective date.
4. Match the model against that document. Check that the document covers residential net metering rather than a tender, a vendor empanelment, a module list or unrelated equipment, and that your phase and capacity fall inside its scope.
5. Collect the conformity evidence the document names. Request the specific test reports or certificates it asks for, for your exact model, with their revision dates.
6. Get the confirmation in writing. Ask whoever is submitting your application to confirm in writing that the named model is acceptable to the named DISCOM under the named document. Keep it.

If you are earlier in the process, the stage by stage net metering application route covers what happens after this, and our net metering guide covers how the credits themselves work.

What to put in writing with your installer

The verification above is only worth the paper it produces. Three sentences in your order confirmation do most of the work.

Name the exact inverter model that is being supplied, and state that substitution requires your written agreement. Model substitution after approval is a common cause of rework, because the approval attaches to the model, not to the order.

State that the installer confirms the named model is acceptable to your named DISCOM for net metering under a named, dated document. This moves a verbal assurance into something checkable.

State who carries the cost if the inverter is refused at inspection for an equipment reason. Without that sentence, the default answer tends to be you.

Red flags in a quotation

Timelines are the other place expectations slip. Approval clocks and the points where applications actually stall are covered in net meter approval time in India, and it is worth reading before you commit to a commissioning date.

Your next step

Write down your exact inverter model code and your DISCOM name, in that order, then work through the six steps above before you release payment for equipment.

If you are still choosing a model, start from the Qbits inverter range and note the exact model code for the capacity and phase you need, so you have something specific to verify. For help identifying which model matches your load and phase before you begin the DISCOM check, talk to a Qbits engineer with your pin code and sanctioned load to hand.
