Tesla · on the approved battery list
Tesla Powerwall, and the listing that quietly lapsed.
The name most people arrive with, and the one where checking the model number on the quote matters most.
Quick answer
Tesla holds 4 approved product lines on the Clean Energy Council approved battery list published by the Clean Energy Regulator, across 20 registered configurations from 13.5 to 54 kWh usable capacity. 1 of those configurations have already lapsed and can no longer earn certificates. A battery only earns the federal certificates if the exact model is on that list on the day it is installed, so the model number on a quote matters more than the brand on it.

What this brand actually does
One system, inverter included — which cuts both ways.
Tesla is the name most people arrive with, and the register shows why the conversation has changed: the current listings are Powerwall 3 and its expansion units, with the original Powerwall now carrying a lapsed approval date. That matters more than brand loyalty, because an expired listing cannot earn certificates no matter how good the hardware is. Powerwall 3 also integrates the solar inverter into the battery rather than sitting alongside one, which is elegant when a system is being designed from scratch and awkward when it is being retrofitted to an existing array with its own inverter — the retrofit case often means replacing equipment that is working perfectly well.
Who it suits
And where it's the wrong pick.
It suits a new solar-and-battery install designed as one system, and a household that values a single manufacturer for the whole chain. It is a harder fit where good solar was installed recently with a separate inverter, because the saving on paper can disappear into replacing that inverter. Check which listing a quote actually refers to before signing: the model number on the quote is what determines eligibility, not the word "Powerwall".

A product line is one family, andsizes is how many separate configurations of it are registered — modular systems are registered once per stack size, which is why some lines show dozens. Usable capacity is the figure the certificate tiers are calculated on, and it is always lower than the nominal capacity printed on the box.Listing expires is the date the Clean Energy Council approval lapses; after it, that configuration can no longer earn certificates. All of it is as published in the Clean Energy Council approved battery list, so you can look up any line yourself.

Tesla batteries — common questions
Is the original Powerwall still eligible for the federal discount?
Check the model on the quote against the register rather than taking the brand name as the answer. The register carries the approval and expiry date for each listed configuration, and a listing that has lapsed cannot generate certificates from the date it lapsed — regardless of stock sitting in a warehouse. This is not unique to any one manufacturer; it is how the approved list works, and it is exactly why the model number matters more than the badge.
Which sizes does Tesla come in?
Tesla holds 4 product lines on the Clean Energy Council approved battery list, registered across 20 separate configurations, running from 13.5 to 54 kWh of usable capacity. That covers up to 14 kwh, 14 to 28 kwh, 28 to 50 kwh. Modular ranges are registered once per stack size, so a high configuration count means flexibility rather than a large catalogue of different products.
Are all Tesla batteries still approved?
No. 1 of the 20 registered Tesla configurations have already lapsed, and 1 product line has lapsed entirely. A lapsed listing cannot earn certificates from the date it lapsed, whatever stock remains in the warehouse. Take the model number from your quote — not the series name — and check it against the register before you sign.
Does Thunderman install Tesla batteries?
Thunderman does the licensed electrical side of a battery installation across Greater Melbourne — the switchboard work, the isolation and protection, the backup circuits and the grid connection — under REC 28523. Which brands Yiannis can supply depends on wholesaler arrangements, so ask rather than assuming from this page: it is a guide to what is on the government register, not a stock list. If you already have a quote for a Tesla system from someone else, he is happy to look at the electrical scope in it.
Whichever badge is on it, the switchboard still has to carry it.
