Meet Soltaro An Australian company's all-in-one battery that runs on the grid, as backup, or fully off-grid.
- Designed and engineered here
Soltaro says it designs and engineers the AIO2 in Australia, and its Australian company holds both AIO2 approved-list entries.
- Charges from solar you already have
The AIO2 can connect alongside an existing solar system and store its spare power, as well as charging from new panels.
- Grid, backup or off-grid
Use it on the grid, as backup, or off-grid; black-start technology lets it recharge from the sun without grid power.
Off-grid systems get 5 years of warranty, not 10.
- Up to 10 years of cover
Five years or 5,000 cycles as standard, plus five more free when bought through a Soltaro retailer and used on-grid.
Ask your installer to confirm they're Soltaro-licensed; the warranty requires it.

Is Soltaro right for your home? Fit and warranty checks
A good fit if…
- Buyers who place real weight on dealing with an Australian company and an Australian warranty counterparty
- Retrofits where keeping the existing solar inverter matters, since the system can be AC coupled
- Households that want battery, inverter and management in one enclosure rather than several boxes
- Owners who will confirm the retailer, the installer’s licensing and the portal connection before signing
Consider the limitations
- A minority of owners reporting long warranty delays is a risk you do not want to carry
- You are going off-grid, which is excluded from the free half of the warranty term
- You want whole-unit replacement rather than parts-only cover
- You want a large body of consistently positive Australian reviews rather than a polarised one
The Soltaro range
All-in-One 2, larger unit
The bigger size, also expandable by two more modules
Additional modules must match the size of the original, so the first choice sets the ladder.
Soltaro hybrid inverter range
Four output sizes inside the all-in-one
Covered by its own warranty term, which is shorter than the battery’s.
Soltaro specifications and source documents
Designed and engineered in Australia, the Soltaro All-in-One 2 combines a battery, inverter and management system in one enclosure. It can be AC or DC coupled, giving your installer options for adding storage to existing solar or designing a new system. Choose the starting size around your home’s needs, with room for up to two matching battery modules later. Your quote should confirm compatibility, usable capacity and the warranty conditions for your installation.
- Current Soltaro line-up in Australia: AIO2-BTLV-5KWH (4.5 kWh usable), AIO2-BTLV-10KWH (9 kWh usable). Source
- Usable capacity runs from 4.5 kWh to 9 kWh. Source
- Capacity can be added later without replacing the inverter. Source
- The manufacturer warranty is 10 years, with 70% of original capacity guaranteed at the end of it. Source
- It works with Soltaro's own inverters only. Source
- Listed models are on the Clean Energy Council approved battery list. Source
- Soltaro requires a manufacturer-certified installer for the warranty to hold. Source
- Both AIO2 battery models are on the Clean Energy Council approved battery list, the hardware condition of the federal Cheaper Home Batteries Program, which covers systems from 5 kWh to 100 kWh of usable capacity. The smaller of the two sits below that floor on its own, so a qualifying Soltaro system starts at the larger unit or at more than one module. Source
Soltaro questions, answered
- Is Soltaro really an Australian company?
- Yes, in the way that matters most. Its warranty document names Soltaro Pty Ltd as a company existing under the laws of Australia with a registered office in Melbourne, and the approved-product register lists the Australian entity as the certificate holder. The products are designed and engineered in Australia and manufactured at the company’s own facility in China. So the counterparty you would claim against is Australian, even though the hardware is not made here.
- What do the bad reviews actually say?
- They are about service rather than the product working on day one. The pattern in the negative reviews is a fault developing and then a long wait for resolution, in one case described as the better part of a year without action. The positive reviews, which are the majority, describe reliable performance and responsive, helpful support. SolarQuotes’ reviewer weighs the split and does not recommend the brand. Treat it as a real risk to price in rather than a certainty.
- Is the warranty ten years or five?
- Both, depending on how you buy it. The battery carries a base term, and Soltaro adds a free extension of the same length again — but only where the product came through its own retail channel, was installed by an installer it has licensed, and is not being used off-grid. Meet all three and you have the full term. Miss one and you have half of it, and nothing about the installed system will tell you which.
- Is Soltaro eligible for the federal battery rebate?
- Both All-in-One 2 battery models are on the Clean Energy Council approved battery list, which is the hardware gate for the Cheaper Home Batteries Program. Note that the smaller of the two sits below the program’s minimum usable capacity on its own, so a qualifying system means the larger unit or more than one module. Ask your installer to confirm the configuration clears the floor.
- What does AC or DC coupled mean for my house?
- It decides whether your existing solar inverter stays or goes. AC coupling puts the battery system alongside the inverter you already have, which suits a retrofit where that inverter is fine. DC coupling integrates the two, which usually suits a new solar-and-battery install. Soltaro supporting both is genuinely useful flexibility, and it means the quote should say plainly which one you are getting and why.
- What is a parts-only warranty?
- It means that unless Soltaro specifically agrees otherwise, a claim results in the defective parts being replaced rather than the whole unit, and the original product is returned to you. It also means that where a repair or replacement happens, the continuing cover does not include the labour of taking the unit off the wall and putting it back. Ask your installer what they would charge for that work, because it is a real cost that the warranty does not carry.
- Can I use Soltaro off-grid?
- You can, and the warranty addresses it directly, but with two consequences. Off-grid use is excluded from the free warranty extension, so the term is the base period rather than the full advertised one. Soltaro also states a minimum amount of storage for most off-grid household systems, which rules out the smallest configuration. If off-grid is your plan, get both points confirmed before you commit.
