Areas We Service Across the Blue Mountains
From the lower mountains to the upper mountains, we provide solar battery installation in Blue Mountains across eligible homes, subject to postcode, site suitability, and scheduling.
Lower Mountains
Lapstone, Glenbrook, Blaxland, Warrimoo, and Mount Riverview sit close to the foothills, with established homes, sloping blocks and plenty of properties where access and existing electrical infrastructure need to be considered before installation.
Springwood & Surrounds
Around Springwood, Valley Heights, Faulconbridge, Winmalee, Yellow Rock, and Hawkesbury Heights, properties range from established family homes to larger bush blocks. Shading, access, and the position of existing solar equipment can all affect system design.
Mid Mountains
Linden, Woodford, Hazelbrook, Lawson, and Bullaburra sit higher along the range, where colder conditions and steep or constrained blocks can make battery placement an important part of the site assessment.
Upper Mountains
Wentworth Falls, Leura, Katoomba, and Medlow Bath experience colder conditions than the lower mountains, making sheltered placement of solar batteries in the Blue Mountains particularly worth considering alongside clearances, ventilation, and access.
Blackheath & Mount Victoria
Blackheath, Mount Victoria, Bell, and Megalong Valley include larger blocks, bushland settings, and properties where heritage or conservation considerations may affect where equipment can be installed.

Solar Battery Costs in the Blue Mountains
What moves the solar battery price in the Blue Mountains isn't a single number, it's a handful of factors:
Usable capacity you need
Single-phase vs three-phase power
Whether a new inverter is required
Retrofit onto existing solar vs a new system
Rebates and current promotions applied
If you're comparing a battery solar systems in the Blue Mountains, it's worth looking at the whole system rather than comparing battery prices in isolation. The right setup depends on how much electricity your household uses, when you use it, and what you want the battery to do.

Where a Battery Can Go in a Blue Mountains Home
Not every home is a straightforward fit, and we'd rather tell you that upfront than after a quote.
What a site assessment checks
- — Clearances from doors and windows
- — Ventilation
- — Proximity to fuel sources
- — Access for servicing
- — Existing solar and inverter setup
- — Switchboard capacity and available installation space
Cold Weather and Battery Placement
Temperatures are lower across the upper mountains, particularly through winter. Batteries have specified operating and charging temperature ranges, so the location matters.
A garage, sheltered wall, or other suitable protected position can often be preferable to an exposed outdoor location. The right position depends on the battery selected, the property and the manufacturer's requirements, so this is something we assess rather than assume.
Bushfire-Prone Properties
Many Blue Mountains properties sit in bushfire-prone areas. That does not mean a battery is a bushfire protection measure, and it should never be presented as one.
It does mean property conditions and bushfire exposure need to be considered when determining where equipment can be placed. We assess this alongside the standard clearance and installation requirements before confirming a suitable position.
Heritage and Conservation
ConsiderationsProperties around Leura, Katoomba, and Blackheath can also have heritage or conservation considerations that affect where external equipment can go.
That may influence the position, visibility, or practicality of a battery installation. We check these property-specific constraints before committing to a proposed location rather than assuming every home has the same options.
Backup During a Power Outage
A compatible battery can provide backup power to selected circuits when the grid goes down.
That could mean keeping important lights, refrigeration, internet equipment, or other nominated circuits running, depending on the system design. It does not automatically mean every appliance in the home will continue operating, and whole-home backup should never be assumed unless the system has specifically been designed for it.
For Blue Mountains households where outages can be a genuine concern, getting those expectations right from the start is important.
Battery Installation Standards
Solar battery installations in the Blue Mountains must meet applicable electrical and safety requirements, including AS/NZS 5139. The standard covers battery positioning, clearances, and protection from potential hazards, which is why the proposed location needs to be assessed before installation.
For the full requirements, see our NSW installation page.
Possible Limitations
Apartments and most strata properties generally can't take a home battery because of shared electrical infrastructure, common areas and battery positioning requirements.
Steep, narrow or restricted-access properties aren't automatically ruled out, but nothing gets promised until the site has been assessed.
We'll tell you what's realistic for your home before you commit to anything.

What Our Customers Say
Stellar Workmanship and Professional Installation
“VoltX Energy's customer service and workmanship has been stellar. They are also very competitive. The technical team is well-versed in all aspects of battery and electrical technology. I had my 48kW system installed within 4 days of paying my nominal deposit. The installation team were very professional and collaborative. They did a super neat job taking the cabling through our double brick walls and through the roof cavity to the meter box. They installed the additional circuit breaker at the main power board and connected everything up very professionally. They cleaned up after the work and left the place tidy.”
Ram, NSW
Huge Difference in Our Monthly Electricity Bill
“Our electricity bills, even with solar and a small battery, were still $400-$600 per month, so we got a VoltX Energy system installed. From receiving the quote to installation was about a week! We realized our usage was so high we struggled to charge the battery, but they set it up so we could get a feed-in from the grid at off-peak. Changed providers and now our bill is around $170 per month! It definitely has made a huge difference. Everyone we have dealt with has been amazing.”
Clay Potts, NSW
Professional Setup Built for Smart Off-Peak Charging
“I got the VoltX Energy battery system installed at our semi. The installation team were very quick and efficient and installed the system exactly where I wanted it with minimal disruption. There were no hidden extra costs. The system works perfectly with no problems. Once setup, it’s easy to see consumption from the batteries. If the batteries need a grid top-up, you can set the recharge time to when the rates are the lowest cost for you, taking full advantage of off-peak pricing.”
Rick & Janie, NSW

If you're looking for solar batteries in Blue Mountains, send us your suburb and postcode and we'll confirm availability. In case you postcode or suburb is not on the list, you may still fill-out this form so we can add you on our waitlist. You'll be one of the first to know in case we start installing on your suburb.
How much does a solar battery cost in the Blue Mountains?
The cost depends on the battery capacity, inverter configuration, whether you're adding storage to existing solar or installing a new system, switchboard requirements, and site access.
Eligible NSW households can currently access VoltX Energy battery systems from $3,999, combining applicable government incentives with an exclusive VoltX Energy discount. Final pricing depends on eligibility and technical assessment.
What's included in a solar and battery package?
A complete package can include the battery, inverter where required, installation, commissioning, and relevant electrical work. The exact configuration depends on your existing solar system, household energy use and property.
If you already have solar, an AC-coupled battery can sometimes be added without replacing a compatible existing solar inverter. We'll assess your current system before recommending an approach.
Do batteries work properly in cold weather?
Yes, provided the battery is installed and operated within its specified temperature range. This is particularly relevant in the upper Blue Mountains, where winter temperatures can be much lower than Sydney.
Battery placement can help. A suitable garage or sheltered location may provide a more appropriate environment than an exposed outdoor position, depending on the system and property.
Will a battery keep my power on during an outage?
A compatible system can provide backup to selected circuits during an outage. Which appliances and circuits remain powered depends on your battery, inverter and installation design.
It does not automatically provide whole-home backup. We'll explain exactly what your proposed system can and cannot run before installation.
Can I add a battery to my existing solar panels?
Often, yes. A site assessment will check your existing solar inverter, panels, switchboard, system configuration and available space.
Adding storage to compatible existing solar can be a practical option if your panels are still performing well. We'll assess the system you already have rather than assuming you need to replace it.
Does a heavily shaded roof rule out solar and battery?
Not necessarily. Heavy shading can reduce solar generation, but it does not automatically rule out a battery.
The important question is how much solar your system actually produces and how that generation lines up with your household's energy use. Existing solar generation data can help us determine whether adding storage makes sense.
How long does installation take in the Blue Mountains?
Installation timing varies depending on the property, system selected, approvals, site requirements, equipment availability, and scheduling.
We'll confirm the expected process and timing once your property and system requirements have been assessed.
