Household solar, batteries and smart inverters can improve the stability and quality of power supplied by the electricity grid, early results from a pioneering trial in regional homes across NSW and Victoria suggest.

The Networks Renewed study – led by the UTS Institute for Sustainable Futures (ISF) and funded by the Australian Renewable Energy Agency (ARENA) – shows that, if managed well, solar and batteries can not only improve power quality but also provide support to vulnerable parts of the grid. Such support will reduce the need for costly network infrastructure upgrades and provide a financial benefit for homeowners.
