How Much Solar Battery Cost for Small, Medium, and Large Homes
More and more homeowners in Australia are using solar batteries to help them keep track of their energy consumption as electricity prices keep going higher. Solar panels provide power during the day, but a solar battery lets you store extra power and utilize it at night or when the power goes out. When picking the correct size solar battery for their home, one of the most common questions people ask is how much solar battery cost.
The truth is that the cost of solar batteries depends on the size of the residence, how much energy it consumes, the battery’s capacity, and how it needs to be installed. This information from Electrical Masters tells you how much solar batteries really cost for small, medium, and large homes. This will help you make a smart choice.

Understanding Solar Battery Systems for Homes
It’s important to know what a solar battery can do before you start talking about prices. Instead of sending extra electricity from your solar panels back to the grid, a solar battery keeps it. You can use this saved energy at night, during peak tariff hours, or when the electricity goes off.
When people look to how much solar battery cost, they often forget that the size of the battery affects how well it works and how much money it saves. A battery that is the right size for your needs can help you use less electricity from the grid and get a better long-term return on your investment.
Electrical Masters makes battery solutions based on the real energy needs of homes, so consumers don’t pay too much or too little for power.
How Home Size Affects Solar Battery Cost
The size of the house is a big factor in how much battery power is needed. The more people, gadgets, and everyday routines you have, the more energy you need. That’s why you need to break down how much solar battery cost by the size of your home.
Let’s look at how much more it costs for small, medium, and large homes.
Solar Battery Cost for Small Homes
Small homes typically include apartments, townhouses, or houses with 1–2 occupants. These homes usually consume less electricity, making them ideal candidates for smaller battery systems.
Typical Battery Size for Small Homes
- Battery capacity: 6.6–7 kWh
- Best for: Lighting, refrigeration, internet, basic appliances
Average Cost Range
For small homes, solar battery systems generally cost between $5,000 and $8,000, including installation. This price depends on battery brand, lifespan, and system compatibility.
If you’re wondering how much solar battery cost for a small home, the key is matching capacity to actual usage. Oversizing a battery for a small household can reduce financial returns.
Is a Solar Battery Worth It for Small Homes?
Yes—especially if:
- You already have solar panels
- You want protection from rising electricity rates
- You use power mostly at night
Electrical Masters often recommends compact lithium batteries for small homes, offering excellent efficiency and long warranties.
Solar Battery Cost for Medium Homes
Medium-sized homes are the most common category and typically include families of 3–4 people. These households use more power due to multiple appliances, air conditioning, and extended evening usage.
Typical Battery Size for Medium Homes
- Battery capacity: 8–13 kWh
- Best for: Kitchens, laundry, cooling systems, entertainment
Average Cost Range
Medium home battery systems usually cost between $8,000 and $12,000 installed. This price reflects higher capacity, improved discharge rates, and greater backup potential.
Many homeowners ask how much solar battery cost for a medium home because they want noticeable bill reductions without overspending. With the right battery size, households can offset peak tariffs and significantly reduce grid reliance.
Savings Potential
A well-sized battery for a medium home can:
- Reduce electricity bills by up to 70%
- Improve solar self-consumption
- Deliver faster payback when combined with rebates
Electrical Masters performs energy audits to design cost-effective systems that balance performance and affordability.
Solar Battery Cost for Large Homes
Large homes typically house 5+ occupants and consume high levels of electricity due to multiple bathrooms, pool pumps, EV chargers, and large HVAC systems.
Typical Battery Size for Large Homes
- Battery capacity: 15–30+ kWh
- Best for: Whole-home backup, EV charging, high-load appliances
Average Cost Range
For large homes, solar battery systems generally cost between $12,000 and $20,000+, depending on capacity and whether multiple batteries are installed.
If you’re evaluating how much solar battery cost for a large household, scalability is essential. Many large homes use modular battery systems that can expand as energy needs grow.
Benefits for Large Homes
- Maximum independence from the grid
- Backup power for critical systems
- Long-term savings on high electricity usage
