The Sheriff family from The Hills Shire, NSW, have learnt how they can maximise their investment in a sonnenBatterie through data and insights. Their home battery storage was able to provide the family of 2 with energy independence, and also change their energy usage behaviour through monitoring their energy patterns in real-time.
The Sheriff family has an 8kWh sonnenBatterie Eco that was installed to complement their family home’s 5.7kWp rooftop solar system in 2018. They uses the sonnen app to monitor how much energy has been produced, stored, consumed and how much excess energy is exported to the grid.
“The sonnen app gives me a good view of how much energy is being produced and what gets stored in my sonnenBatterie. This data helps me evaluate what chores I might do in my house. I can run a load of washing and use the vacuum cleaner in the morning to take advantage of the excess energy stored before the sun rises. Instead of exporting any unused solar energy back to the grid, I’ve chosen to use this to power up my dishwasher, pool pump, clothes dryer and even ironing,” Mr Sheriff said.
Having built his family home back in 2008, they installed a 10kW centrally ducted heating and cooling system that serves their five-bedroom home. The heating and cooling system is programmed to operate in zones, to optimise energy efficiency by heating or cooling areas where the majority of occupants will reside for the day.
During winter, the heating system has been automatically timed to run between 5:30 am to 7 am as the Sheriff household prepares to head for work. In the evening, the heater runs from 4:30 pm to 7 pm and this is programmed to be switched on again from 10 pm to 11:30 pm as the family retires for the night.
