Most battery problems start before the system is installed. They start with a quote that skipped a few questions. A GoodWe all in one battery can suit many Australian homes, but the result depends on how well the installer plans the job.
This guide covers what to ask, why it matters and what a good answer sounds like. You can use it as a checklist when you compare quotes.
What an All in One Battery Actually Includes
An all in one system combines the battery and the hybrid inverter in a single unit. That means fewer separate boxes on your wall and a simpler installation than a traditional setup with a standalone inverter and battery.
A GoodWe all in one battery is built to manage solar generation, battery charging and power supply to your home together. The GoodWe ESA series, for example, is a modular LiFePO4 battery that starts at 5.12kWh and can be stacked up to 49.92kWh as your needs grow.
The tidy design does not remove the need for good planning. The questions below are where most of the value is.
Questions About Your Home and Your Existing Solar
Will the system suit my current solar setup?
If you already have solar panels, ask whether your existing inverter will stay or be replaced. An all in one unit has its own inverter, so some homes end up with two inverters on site.
Your installer should explain how the new unit will connect to your panels and whether your current system needs changes. A vague answer here usually means they have not looked at your setup properly.
How will you size the battery for my household?
Sizing should come from your actual usage, not a standard package. Ask the installer to look at your electricity bills or smart meter data, especially your evening consumption.
A household that uses most of its power after sunset needs different capacity from one that is home all day. Ask them to explain why they chose a particular size and what happens if your usage changes. With a stackable system, expanding later may be an option, so ask about that too.
Is my switchboard ready for this?
Older switchboards sometimes need upgrades before a battery can go in. It is better to hear that during the quote than on installation day.
Ask whether any switchboard work is included in the price or would be quoted as an extra.
Questions About Backup Power
What will actually run during a blackout?
This is the most misunderstood part of home batteries. Having a battery does not always mean your whole house stays on during an outage.
Ask these directly:
- Is backup power included, or does it need extra wiring or hardware?
- Which circuits will be backed up?
- Can the system run heavy appliances such as an oven, ducted air conditioning or a pool pump?
If you live somewhere with regular storms or grid interruptions, the answers may change which model or setup you choose.
How quickly does backup power switch on?
Ask how the changeover works when the grid drops out. If you work from home or run medical equipment, the detail matters more.
A GoodWe all in one battery may suit your needs well, but only if the backup configuration matches what you expect from it.
Questions About Installation and Compliance
Who will install it, and are they accredited?
Battery installations in Australia need to follow set standards. Ask whether the installer holds the right accreditation and whether the work will follow AS/NZS 5139, the standard that covers battery system installation.
Ask who does the work too. Some companies send their own team, while others subcontract. Both can be fine, but you should know which one applies to you.
Where will the unit be placed?
Location affects safety, performance and appearance. Installers should be able to explain where the unit can go, what clearances it needs and whether it suits indoor or outdoor mounting.
Ask for the proposed spot to be marked at the site visit. It avoids surprises later.
Will you handle network approval?
Your local electricity distributor usually needs to approve changes to your solar and battery setup. Ask whether the installer lodges the paperwork and how long approvals typically take in your area.
Also ask about export limits. Some networks cap how much solar you can send back to the grid, which changes how much value you get from a battery.
Questions About Money, Rebates and Savings
What does the quote include?
A low headline price can hide missing items. Ask for a written breakdown covering the unit, installation, wiring, compliance paperwork, any switchboard work and monitoring setup.
Compare quotes line by line, not just by total.
Questions About Warranty and Long-Term Support
What does the warranty cover?
Ask for the warranty terms in writing. You want to know how long the battery and inverter are covered, what the warranty says about capacity over time and who handles claims.
This matters with a GoodWe all in one battery because the inverter and battery share one unit. Ask whether they are covered under a single warranty or separate terms.
Who do I call if something goes wrong?
Find out whether support comes from the installer, the manufacturer or both. Ask how long the installer has been operating, and whether they will still be around in five or ten years.
A company with local service and a track record is worth more than a small saving upfront.
Can I monitor the system myself?
Most modern systems come with an app that shows solar production, battery charge and home usage. Ask for a demonstration of how it works and whether the monitoring setup is included.
Being able to see your system in real time helps you spot problems early and understand your energy habits.
Red Flags Worth Noticing
Be cautious if an installer:
- Quotes without checking your usage or switchboard
- Pushes you to sign the same day
- Cannot clearly explain backup limitations
- Avoids giving warranty details in writing
Good installers welcome questions. If the answers feel rushed or evasive, take that as useful information.
