Turn Sunlight Into Hot Showers: How Fronius Ohmpilot Supercharges Solar Self-Consumption

With electricity prices on the rise and more Australians switching to solar, getting the most out of every kilowatt-hour your PV system produces is essential. One of the best ways to maximise your self-consumption and shrink your bills is to put surplus solar power to work in heating your water and no device makes this easier than the Fronius Ohmpilot.

Make Every Ray Count: Convert Excess Solar to Hot Water

A well-designed photovoltaic system will often generate more energy than your home can use during the sunniest parts of the day. Traditionally, this surplus is exported to the grid for a small feed-in credit. But what if you could keep this valuable energy on-site, saving even more money and boosting your independence from the grid?

The Fronius Ohmpilot is the smart link that directs excess solar energy straight into your hot water system. Instead of letting precious rays go to waste or earning a minimal return from your retailer, Ohmpilot automatically senses when surplus solar is available and ramps up your electric hot water heating, storage tank, or panel heater. This simple shift means more of your solar investment pays off for your household not someone else’s.

Reduce Bills, Raise Comfort, and Lower Your Carbon Footprint

Heating water is one of the highest energy expenses for Aussie homes, but with Fronius Ohmpilot, you can cover a substantial portion of this cost with your own green power. By utilising the free sunshine streaming onto your rooftop, households can raise their energy self-sufficiency dramatically often pushing solar self-consumption above 60%, far better than the typical 20–40%.

The benefits don’t stop at your budget. Because your heating system isn’t relying on gas, oil, or expensive grid power as often, you can extend its service life and reduce environmental wear and tear. In many cases, homeowners can even switch off their boiler or main heating during the summer months, slashing costs even further and minimising maintenance. It's a real win for both your pocket and the planet.

Automated, Intelligent Management, No Guesswork Required

Designed to be used with Fronius PV inverters and fully integrated into the Fronius Solar.web platform, Ohmpilot puts intelligence and automation at the heart of your hot water solution. The system continuously monitors household electricity consumption, solar generation, and hot water temperature, automatically adjusting output for the smartest use of every surplus watt.

Set-and-forget operation means you won’t need to lift a finger: your system senses when there’s surplus solar and puts it to work immediately, prioritising hot water or heating whenever extra power is available. With remote monitoring via Solar.web, it’s easy to see the benefits in real time, spot opportunities to further increase your savings, or plan for future upgrades like batteries or EV charging.
