Can I still add a battery to a SolarEdge system?

Yes, you can still add a battery to a SolarEdge solar system, and you do not need a SolarEdge battery to do it. A battery with its own inverter connects at the switchboard and works beside whatever solar you already have. Your SolarEdge inverter and optimisers stay exactly as they are. With SolarEdge closing its Australian operations, that is now the way we would go for almost every SolarEdge owner.

Why not a SolarEdge battery?

Because you would be buying a long life product from a company that is leaving. SolarEdge has told its installers it will take final Australian orders on 20 November 2026 and deliver the last of them by 18 December 2026. It will stop renewing its product certifications, and support moves to its International Tech Centre. SolarQuotes reports that the new stackable battery SolarEdge showed at the All Energy trade show will not be sold here.

A SolarEdge battery connects straight into a SolarEdge inverter, so it relies on SolarEdge for parts, software and warranty for its whole life. The warranty should still be honoured, as SolarEdge is still trading overseas. But a battery is the part of a system most likely to need a maker's help, and we would not want a customer's only path to that help to be an overseas call centre.

How does a battery work beside a SolarEdge system?

It is wired in on the AC side, which the trade calls AC coupled. The battery has its own inverter and its own meter at the switchboard. That meter watches what the house is using and what the solar is making. When the solar makes more than the house needs, the battery charges from the spare. When the sun goes down, the battery runs the house.

The SolarEdge side does not know the battery is there, and does not need to. Nothing on the roof changes. Your optimisers, your panel level monitoring and your SolarEdge warranty carry on as before.

What you end up with is two apps: mySolarEdge for the panels, and the battery maker's app for the house, the battery and the grid. Most owners end up using the battery app day to day, since it shows the whole picture.

Do I still get the federal battery discount?

Yes, if the battery itself qualifies. The Clean Energy Regulator says a battery can be installed with new or existing solar, must be on the Clean Energy Council's approved battery list, and must be between 5 and 100 kWh. It also says the existing solar system does not need to be on the approved list. So an older SolarEdge system does not stop you claiming the discount on a new battery of another brand.

The discount comes off the price through your installer and steps down over the years to 2030, so the amount depends on when the battery goes in. The Regulator's solar batteries page has the current rules.

What should I check before I sign?

A battery added to an existing system needs a few things settled first. A good quote answers all of these in writing.

• Network approval. A battery inverter adds to the inverter capacity at your address. Your network, which is Powercor across most of Central Victoria, has to approve it and may set a limit on what you can send back to the grid. Your installer makes the application.
• Backup in a blackout. Not every battery install gives you power in a blackout, and those that do need a backup circuit or a gateway at the switchboard. Ask what will run in an outage and for how long.
• Whether the solar keeps working in a blackout. With some batteries the existing solar can keep charging the battery while the grid is down, and with others it switches off until the grid returns. It depends on the battery and how it is wired. Ask the question directly.
• Switchboard room. An older switchboard may need work to take the new breakers and the meter.
• Where the battery goes. There are rules about how close a battery can be to doors, windows and living areas. The spot you have in mind may not be the spot it can go.
• Single phase or three phase. The battery inverter has to suit your supply.

What if my SolarEdge inverter is getting old?

Then look at the whole system, not only the battery. If the inverter is near the end of its warranty, there is a case for replacing it with a hybrid inverter that runs both the panels and the battery, which gives you one maker, one app and one warranty. The cost of going that way with SolarEdge is on the roof: the optimisers only work with a SolarEdge inverter, so they all have to come off. We explain that in what your options are when a SolarEdge inverter fails.

If the inverter still has years of warranty left, leave it alone and add the battery beside it.

What we install

We are Trentham Energy, licensed electricians and solar installers based in Trentham, working across Central Victoria and the Macedon Ranges. We install the Sigenergy SigenStor, the Fronius Reserva, GoodWe and FranklinWH batteries. Which one suits a SolarEdge home depends on the switchboard, the supply and what you want it to do in a blackout, and we will say so plainly if one of them is the wrong fit.

Send us a recent bill, your address and a photo of your SolarEdge inverter label, and we will come back with a right sized design: get in touch.

Questions

Does adding another brand of battery void my SolarEdge warranty?

A battery wired in on the AC side does not alter the SolarEdge equipment, so there is nothing in it for the SolarEdge warranty to object to. Any work that opens or rewires the SolarEdge inverter itself is different, and should be checked against the warranty terms first.

Can a battery charge from SolarEdge solar?

Yes. The battery's meter sees the spare solar at the switchboard and charges from it, whatever brand of inverter made it.

Is the SolarEdge Home Battery still available in Australia?

Only from stock already ordered. SolarEdge's final Australian orders close on 20 November 2026.

Will I need a new inverter to add a battery?

Not for the solar. The battery comes with its own inverter, and the SolarEdge inverter keeps running the panels.
