Australia is a world leading country for domestic photovoltaic (PV) solar power, with over 2 million solar power systems installed. PV owners and electricity networks are increasingly looking for ways to store electricity and maximise this enormous solar investment while maintaining network stability.


Solahart, Australia’s original solar brand since 1953, has developed Australia’s first smart electric water heater, the Solahart PowerStore, to provide a cost-effective way of rapidly introducing large amounts of controlled energy storage into the electricity network; stabilising the grid, enabling more uptake of renewable energy and ultimately reducing power bills for Australian households and businesses.


Unlike conventional water heaters, Solahart PowerStore uses advanced technology developed at its R&D facility in Sydney, to take excess energy from solar power panels and use it to heat water gradually throughout the day, rather than allowing it to be fed back into the grid. The concept works much like a battery but is far more affordable.


Solahart PowerStore includes a Home Energy Management System (HEMS) that supports the integration, control and orchestration of other distributed energy resources including batteries, pool pumps, air conditioning, PV, floor heating and Electric Vehicle Charging for further significant savings. The HEMS optimises performance based on weather, tariff and price signalling and is ready for cost reflective tariffs. It also enables participation in AEMO Frequency Control Auxiliary Services (grid security of supply) for customer’s financial gain.


With over 9 million water heaters currently installed in Australia and 25% of household energy consumption being used for hot water heating, smart controllable water heating is a rapid and cost-effective way to improve the electricity network and reduce consumer energy bills.


Solahart PowerStore recently featured in several news articles including “Wise ways with water” from the Nov-Dec 2018 issue of the Smart Energy Council’s Solar and Storage magazine.
