Power bills climbing? Family energy use growing? You’re not alone. Across Australia, medium-sized households are turning to smarter solar and battery solutions to stay in control of their energy. At NexaPower – the best solar company in Australia, we’ve seen one system stand out again and again for balanced performance and value: the 7.5kW solar system paired with a Sofar battery.
This setup isn’t about overloading your roof with panels or investing in more than you need. It’s about right-sized power, steady savings, and reliable backup for everyday Australian homes.
Let’s break it down in a clear, practical way — no buzzwords, just real answers.
Why the 7.5kW Solar System Is Ideal for Medium Homes
A 7.5kW solar system is often called the “sweet spot” for medium households. It’s powerful enough to cover most daytime usage while still being cost-effective.
This system is a strong fit for homes with:
3–5 people
Air conditioning and heating
Home office or remote work
Electric cooking appliances
Growing power needs
On an average sunny Australian day, a 7.5kW system can generate enough power to handle daily use and still export excess energy back to the grid.
At NexaPower, we design these systems for real household load, not just ideal calculations.
Why Pair It with a Sofar Battery?
Solar is only half the story. A battery makes your system truly smart.
The Sofar battery is built for:
Reliable energy storage
Stable performance in Australian conditions
Clean, efficient charge and discharge cycles
Long service life with strong safety controls
During the day, your solar panels power your home and charge the battery. At night or during peak grid times, your home runs on stored solar energy instead of expensive grid power. That’s where the real savings happen.

How This System Works in Everyday Life
Instead of thinking in technical terms, think in daily routines.
Morning: Your solar starts generating power as the sun rises. Kitchen appliances, washing machines, and early device charging are powered by your panels.
Midday: Excess energy charges your Sofar battery while still exporting power to the grid.
Evening: As solar production drops, your battery takes over, running lights, TVs, air-conditioning, and cooking appliances.
Night: You rely less on grid power and more on stored solar — keeping costs predictable.
That’s what smart energy really means: your home staying powered with minimal grid dependence.

Australia’s heat, dust, and power fluctuations demand tougher equipment. At NexaPower – the best solar company in Australia, we select systems that are tested for:
