Checking the inverter and battery against the register at design stage saves a rejected notification or a stalled G99 application later. Here is where the register is now, how to search it, what the statuses mean and what to do when the product you want isn't there.

From the live register, Connect Direct's FAQs, the ENA's connection guide and NGED's G99 Form A1-1, read on 9 November 2026.

Where the ENA Type Test Register is now

The ENA's connection guide says the Type Test Register closed on 16 April 2024 and all its data and functions moved to the Connect Direct portal. Connect Direct's FAQ confirms it has replaced the register: every device on the old register was migrated, and the old register no longer takes new registrations. For manufacturers it also replaced the ENA's separate EV charger and heat pump spreadsheets.

So when an installer, wholesaler or DNO says "the ENA register" or "the ENA database", they mean the Live Device Register on Connect Direct. On 9 November 2026 it listed 9,743 devices. The same portal is where installers make domestic connection applications; our ENA Connect Direct guide covers that side.

What type tested and Fully Type Tested mean

EREC G99 defines type tested equipment as a product tested to show the design meets its requirements, where the manufacturer declares that every similar product supplied is built to the same standard and performs the same. Inverters, generating units and interface protection can all be type tested. The manufacturer follows the test methods in the annexes of G98 or G99 and produces a Type Test Verification Report (for G98, that is Form C).

When the whole Micro-generator or Power Generating Module is type tested, not just part of it, it is Fully Type Tested. The ENA guide says every Micro-generator connecting under G98 must be Fully Type Tested, and that the same idea applies in G99. It also reminds owners that procuring and installing compliant equipment is their responsibility, which on a job you supply means checking it yourself.

How to look up an inverter on the ENA register, step by step

1. 1

   Open the Live Device Register

   Go to connect-direct.energynetworks.org and choose Live Device Register. The page is headed "Search the ENA Type Test Register". We searched it without logging in on 9 November 2026.

2. 2

   Filter by manufacturer and model

   Open Filters and pick the Manufacturer, then the Model. You can also filter by Category, Type (for example PV, Energy Storage Device or Plug-in Solar), Compliance Status, Phase, System Reference and Jurisdiction.

3. 3

   Match the exact unit

   Check the capacity in kW and the phase against the unit on your design. Models in one range are listed one by one, each with its own rating and reference.

4. 4

   Check the compliance status

   Look for Compliant. A Non-compliant unit must not be connected, and one with a minor non-compliance or document error isn't accepted as compliant until the manufacturer fixes it.

5. 5

   Copy the System Reference

   Clicking a row copies its System Reference to your clipboard. Keep it with the job for the G98 or G99 paperwork.

6. 6

   Put it on the form

   On G99 Form A1-1 it goes in the Manufacturer's Ref No. column; the ENA guide says that for a Fully Type Tested unit registered on Connect Direct, quoting it is all you need to show compliance.

Each result shows the System Reference, compliance status, date published, manufacturer, model, category, type, capacity (kW) and phase. The newest entries come first. On 9 November 2026 the references looked like five letters, a number and a version, such as AIRAG/21914/V1/A2.

What each compliance status means

From the ENA's connection guide. Only Compliant means the ENA has accepted the product:

What to do if a product isn't listed

• Check the spelling, then the rating. Manufacturers name their own entries, sometimes with a trading name in brackets. Filter by manufacturer first and scan the models, then check kW and phase.
• On a G98 job, you need a listed, compliant unit. Every Micro-generator connecting under G98 must be Fully Type Tested. The only exception in the ENA guide is where the DNO agrees it is impractical, such as a micro hydro unit designed for its site. Otherwise pick a product that is on the register as Compliant.
• On a G99 job, send compliance evidence instead. Equipment that isn't Fully Type Tested needs a Compliance Verification Report (Forms A2-1 to A2-3) before commissioning is arranged, and possibly on-site tests (Form A2-4). If only part of it is type tested, quote the reference you have and send the A2 form with the application, as Form A1-1 says.
• Ask the manufacturer to register or update it. Only the manufacturer can add a product: it uploads and maintains the Type Test Verification Report on Connect Direct, and the ENA reviews it. A new or amended entry starts as Awaiting Assessment, which can take up to 4 weeks.
• Check older stock. The ENA guide warns that changes to G98 and G99 that alter the technical requirements can end a product's Fully Type Tested status for newly manufactured units until the manufacturer has it reassessed.

The A2 forms and when each is due are in our G99 application guide and the printable G99 checklist. Export limiting devices have their own rules: the ENA says G100 devices used for G99's small installation procedures must be Fully Type Tested too, as our G100 guide explains.

Where the reference goes on the G98 and G99 forms

• G98 Form B: each Micro-generator gets a line with its type test reference. Our G98 form guide goes through Form B field by field.
• G99 Form A1-1: each existing and proposed generating unit has a Manufacturer's Ref No. column. The ENA guide says a Fully Type Tested unit registered on Connect Direct has a manufacturer's reference (or Product ID), and quoting it means you don't need to send anything more to show compliance.
• Connect Direct applications: you pick the make and model from the same register as you apply.

Not sure which network operator the form goes to? Our DNO application guide finds it from the MPAN.

The ENA register vs the MCS product directory

They answer different questions. The ENA register shows whether a product meets the network operators' connection rules. The MCS Product Directory lists MCS certified products, which matter when the installation is MCS certified (for example, for a customer who wants the Smart Export Guarantee). Check both at design stage; our guide to the MCS database and product directory covers the MCS side, and MIS 3002 the MCS design rules.

Getting the kit right is half the job; the other half is having commercial jobs to put it on. Solar Surveys UK books qualified commercial solar survey appointments with business owners, and you only pay for appointments that are actually attended.
