Thomas Smarter Home with a Battery Upgrade | Winston Hills
System Type – Existing SMA solar system (installed by RK Solar in 2020) upgraded with a Sigenergy battery
Installation Date – July 2025
System Phase – Single-phase system and meter
Rebate – Eligible for the 2025 Federal Government Battery Rebate
In July 2025, Thomas from Winston Hills decided it was time to take his solar setup to the next level. He upgraded his existing SMA and solar system with a smart new battery and with the help of the Federal Government’s Battery Rebate, he was able to lower his upfront costs while boosting energy independence.
Thomas already knew the RK Solar team well. Back in 2020, we installed his original SMA solar system. Happy with the performance and service, he came back to us when he was ready to add battery storage.
For his upgrade, Thomas chose the SigenStor EC 5.0SP inverter and Sigen Energy Gateway SP, paired with 2 x Sigenergy SigenStor BAT 8.0 modules. This setup gives him plenty of stored energy to –
Cut down on electricity bills – Instead of buying power from the grid during peak times when it’s most expensive, he can use the energy stored in his battery. This means he makes the most out of the solar power his system produces during the day, leading to lower bills each month.
Reduce reliance on the grid – By storing excess solar energy, he doesn’t have to depend as much on the electricity grid. The more of his own solar power he uses, the less vulnerable he is to rising energy prices and supply issues.
Enjoy backup power during outages
We also upgraded his meter and configured everything for his single-phase system, ensuring the battery works seamlessly with his existing solar setup and meets all network requirements.
His home now has smarter energy storage, reliable backup, and a system ready for the future.

James Powers Up His Home with a Second Tesla Powerwall | East Ryde, NSW
System Type – Second Tesla Powerwall 2
Installation Date – July 2025
System Phase – 3-phase meter setup
Rebate – Eligible for the 2025 Federal Government Battery Rebate
James, a homeowner in East Ryde, already knew the benefits of having a Tesla Powerwall. His first battery had given him peace of mind, backup protection, and big savings on electricity bills. But as his family’s energy needs grew and his household relied more on electric appliances, he realised one battery wasn’t enough.
That’s when James decided to add a second Tesla Powerwall 2 to his home.
Why a Second Powerwall?
For James, this upgrade wasn’t just about storing more energy, it was about future-proofing his home. With a second battery, he could –
Double his backup power for longer outages – One Powerwall can keep the lights and essentials running, but two give him extended backup capacity. This means he and his family can stay comfortable and powered up for much longer when the grid goes down.
Run high-demand appliances like his oven even during blackouts – Cooking is an important part of daily life. With the added capacity, James doesn’t need to compromise, he can continue using his oven, even if the grid isn’t available.
Store more excess solar energy for night-time use – His solar panels generate plenty of power during the day. With two Powerwalls, James can store much more of that clean energy and use it after the sun goes down, reducing how much electricity he needs to buy from the grid.
Further cut down on energy bills – By maximising self-consumption of his own solar power, James is relying less on expensive grid electricity. Over time, this adds up to even greater savings on his household energy bills.
Complete Control at His Fingertips
With the Tesla app, James can monitor his energy usage in real time, reserve power for blackouts, and optimise savings during peak tariff times. He now has full control over how his home uses and stores electricity.

Benefits of the System
Peter’s upgraded solar and battery solution allows him to –
Significantly reduce energy bills – By generating and storing his own solar power, he uses less electricity from the grid, which lowers his monthly energy costs.
Use clean, sustainable energy even when the sun isn’t shining – The batteries store excess solar energy during the day so he can use it at night or on cloudy days, ensuring he still relies on renewable energy rather than grid electricity.
Lower his household’s carbon footprint – Using solar energy instead of electricity from fossil fuels reduces the greenhouse gases his home produces, making his household more environmentally friendly.
Enjoy a reliable, high-performance energy system tailored to his home – The system is designed to meet his specific energy needs, providing consistent power, handling high-demand appliances, and ensuring everything runs smoothly even during outages.
