Why did the solar panel break up with the grid? Because it wanted to store its energy for later! Speaking of storing energy, we get asked the same five questions about home battery installation in Melbourne every single day. The good thing, as a Master Electrician with over 170 five-star Google reviews, we have answers for all these questions.
Here’s your complete guide to home batteries in Melbourne – five minutes, five questions, zero confusion. We promise to keep it as straightforward as our installation process (and yes, we’re always on time and always clean up after ourselves!).
What Size Home Battery Do I Need in Melbourne?
This is hands down our most popular question, and for good reason. Getting the size wrong is like buying jeans online – disappointing and a hassle to fix.
Here’s the simple rule: a 6-7 kWh battery covers about 90% of an average Melbourne household’s evening energy needs. If you’re running a larger household with teenagers who think the fridge door is a form of entertainment, you’ll want to look at 10+ kWh systems.
Think about it this way:
- Small household (1-2 people): 5-7 kWh battery
- Average family (3-4 people): 8-12 kWh battery
- Large household (5+ people): 13+ kWh battery
The beauty of modern battery systems is that many are modular. You can start with one unit and add more capacity later – kind of like LEGO, but way more expensive and infinitely more useful.
A quick sizing tip: look at your electricity bill and find your evening usage (typically 4pm-10pm). That’s roughly the battery capacity you’ll want to aim for.

How Much Does Home Battery Installation Actually Cost in Melbourne?
Ah, the money question. Why do electricians make good comedians? Because we know how to deliver the punchline with perfect timing – just like our quotes.
Here’s the real talk on Melbourne home battery costs in 2025:
Typical battery system costs:
- Small system (6-8 kWh): $8,000-$12,000
- Medium system (10-13 kWh): $12,000-$18,000
- Large system (15+ kWh): $18,000-$25,000+
Remember, these are a ballpark only depending on your situation and what’s required to install a battery at your place. For example, tricky installations might cost more.
But wait, there’s good news! Victoria is throwing money at battery installations like confetti at a wedding:
Victorian interest-free loan: Up to $8,800 over four years (that’s literally free money). Want more information on this? Read our article: Victorian Home Battery Rebates and Incentives in 2025: Your Guide to Solar Victoria Programs.
New federal battery rebate: Starting July 2025, you’ll get approximately $330 per kWh off the cost – that’s about 30% off your total system price.
Real example: A popular 13 kWh system might cost $15,000. With the federal rebate (~$4,300) and the Victorian loan covering the rest, you could be looking at almost no upfront cost. Your main expense becomes the loan repayments of around $110 per month – which is often less than what you’ll save on your electricity bill.
At Luno Electrical, we provide transparent pricing with all rebates calculated upfront. No nasty surprises, no hidden costs, and definitely no pushy sales tactics.
How Long Do Home Batteries Actually Last?
Good question! How long does a home battery last? Longer than your phone’s battery life, shorter than your mortgage, and hopefully longer than your last relationship!
The straight answer: 10-15+ years minimum, with most manufacturers offering 10-year warranties. Modern lithium-ion batteries are incredibly reliable – they’re essentially the same technology powering electric cars.
Here’s what affects battery lifespan:
- Quality matters: Stick with CEC-approved brands like Tesla Powerwall, Sungrow, or BYD
- Installation quality: Poor installation kills batteries faster (hint: choose Master Electricians like us)
- Melbourne’s climate: Actually perfect for batteries – not too hot, not too cold
Maintenance requirements? Practically zero. No moving parts, no oil changes, no cleaning required. The battery management system handles everything automatically. Software updates happen remotely.
Most batteries will still retain 70-80% of their original capacity after 10 years, which is when the warranty typically ends. But many keep working well beyond that.
Are Home Batteries Actually Worth It in Melbourne?
Is a home battery worth it? That’s like asking if coffee is worth it – technically optional, but life’s just better with it.
Let’s crunch some real Melbourne numbers:
Typical Melbourne household with solar + battery saves $1,300-$2,250 per year. Here’s how:
- You’re currently selling excess solar for about 5 cents per kWh
- You’re buying evening power for 25-40 cents per kWh
- Store that daytime solar instead of selling it cheap, use it when power is expensive
Real example:
- 10 kWh of stored solar per day
- Save 25 cents per kWh (difference between buy/sell rates)
- Daily savings: $2.50
- Annual savings: ~$900+
With the new rebates, payback periods are now 5-7 years. After that, you’re essentially getting free electricity from your stored solar.
Bonus benefits in Melbourne:
- Backup power during storms (remember the 2022 floods?)
- Protection from rising electricity prices
- Increased property value
- Sleep better knowing you’re energy independent
