Battery Benefits: Real Stories, Real Results
Grant’s solar & battery system powered his home for six days during Cyclone Alfred
When Cyclone Alfred hit, Grant’s suburb lost power for six days. But thanks to his solar and battery system from Nectr, his home stayed powered — and connected. Grant was able to keep his fridge, lights, internet and TV running. That internet connection became a lifeline for the community, allowing neighbours to contact loved ones when no one else could.
If we didn't have a battery, we wouldn't have free power at night
Rosie from Brisbane used to pay up to $900 a month for electricity. Now, with a Nectr solar and battery system, her bills are $0. After a personalised home assessment, we installed rooftop solar and a Sungrow battery—now her entire home, including TVs, appliances, and even the outdoor spa, runs on solar.
