BYD · on the approved battery list
BYD Battery-Box, built to be added to.
Modular boxes rather than fixed models, which means the size of your system is a decision made on site.
Quick answer
BYD holds 7 approved product lines on the Clean Energy Council approved battery list published by the Clean Energy Regulator, across 46 registered configurations from 5 to 29.69 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. 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
Specified as a module count, not a model.
BYD's Battery-Box lines are among the most widely installed in Australian homes, and the register shows a design philosophy rather than a product: several parallel families, each built from stackable modules, so the same line covers a small starter system and a much larger one by adding boxes. The practical consequence is that BYD systems are usually specified as a module count rather than a single model, and that the eventual size is a decision made on site. The other consequence, and the one worth knowing before you plan around it, is that these lines are aimed squarely at the household end of the range rather than the large commercial end.
Who it suits
And where it's the wrong pick.
It suits an owner who wants to start at a sensible size and add capacity later without replacing the system, and who is pairing it with a third-party hybrid inverter — compatibility between a specific Battery-Box model and a specific inverter is a real constraint and needs confirming before order, not after. It is a weaker fit for very large installations, where the range runs out before the requirement does.

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.

BYD batteries — common questions
Can I add more modules to a battery later?
With a modular system, often yes — that is the point of the design — but it is not automatic and it should be planned at the first install rather than assumed. Three things decide it: whether the same module is still an approved, available product when you come back to it; whether the inverter you already have can handle the larger stack; and whether the space, mounting and isolation were set up with the expansion in mind. Expanding a system also means the electrical work gets revisited. Ask for the expansion path in writing at the first quote — it costs nothing to ask and it is the difference between adding a module and replacing a system.
Which sizes does BYD come in?
BYD holds 7 product lines on the Clean Energy Council approved battery list, registered across 46 separate configurations, running from 5 to 29.69 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 BYD batteries still approved?
No. 1 of the 46 registered BYD configurations have already lapsed. 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 BYD 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 BYD 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.
