Growatt · on the approved battery list
Growatt, a range that stops where the program does.
Current listings across the board, sized to the capacities the household program was built to support.
Quick answer
Growatt holds 6 approved product lines on the Clean Energy Council approved battery list published by the Clean Energy Regulator, across 50 registered configurations from 4.5 to 50 kWh usable capacity. As at 2026-08-20 none had lapsed. 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. Thunderman Electrical and Air Conditioning Services does the licensed electrical side of battery installation across Greater Melbourne under REC 28523 — which brands can be supplied depends on wholesaler arrangements, so ask.

What this brand actually does
Built for the band the certificates actually favour.
Growatt's listed lines are current across the board, with nothing lapsed on the register at the time of writing, and the range is built to stop at the ceiling the household program supports rather than pushing past it. That is a coherent position: the lines cover the sizes where certificates are actually worth claiming and do not chase the very large capacities where the certificate factor falls away. As with most stackable systems, the size is settled on site by module count, and compatibility with the chosen hybrid inverter is the constraint that decides the design.
Who it suits
And where it's the wrong pick.
It suits a mainstream household installation where the goal is a well-matched, currently-listed system rather than the largest possible one. It suits buyers who want the certificate side to be straightforward. It is a weaker fit for a large commercial or rural site whose load genuinely exceeds what the household program was built for — that requirement is real, it simply sits outside this range.

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.

Growatt batteries — common questions
Does a bigger battery always mean a bigger discount?
No, and since May 2026 the relationship has been deliberately uneven. Certificates are calculated with a factor that steps down as usable capacity increases — full weighting for the smallest band, substantially reduced for the middle band, and much lower again above that — with nothing claimable beyond the first 50 kWh of usable capacity. The government's stated intention was to keep the support proportionate across small, medium and large systems rather than to reward size. So the right question is not how large a battery you can get supported, but how large a battery your household actually empties overnight.
Which sizes does Growatt come in?
Growatt holds 6 product lines on the Clean Energy Council approved battery list, registered across 50 separate configurations, running from 4.5 to 50 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 Growatt batteries still approved?
As at 2026-08-20, none of the 50 registered Growatt configurations had lapsed, though 6 lapse within six months. That can change between one publication of the register and the next, so the model number on your quote is still worth checking — the earliest expiry currently listed for the brand is 2026-11-30.
Does Thunderman install Growatt 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 Growatt 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.
