Solar plus storage is an Adelaide family’s way to zero electricity bills.


Electricity bills always find a way to surprise customers – and not in a positive way. Summer is especially daunting with air conditioners in full use. But even in winter, power rates are susceptible to increase. This makes households, and even businesses, think hard on how they can lower their bills.

For a family in South Australia, the objective is to eventually make the bill go away. And it seems they’ve found a way to make this happen. Their secret: solar plus storage.

Solar plus storage

Adelaide’s Scott Matthews and Kelly Nestor thought of improving their existing solar power system. Installing more solar and battery storage seemed reasonable. After all, they liked how their solar panels worked in slashing their power bills. They used not just any kind of solar storage but opted for one that’s state-of-the-art.

The family worried about their electricity consumption as, over time, the bills only increase. With solar panels, their household budget improved drastically. Now that they have powerful battery storage, they expect the bills to soon reach zero.

Aside from huge savings, the family loved the fact that they are not only helping the environment by reducing energy carbon emission but also teaching their kids about sustainability.

Fronius battery storage system  

The household’s 10kW rooftop solar system worked well with the newly-installed 6kWh Fronius Solar Battery. The family was, in fact, the first in the state to use the Fronius battery. Thanks to National Renewable Group (NRG), the local-based company that installed the battery.

Fronius is well-known for its PV inverter technology and has now branched into the battery storage space. Its product uses lithium-iron phosphate (LiFePO4) chemistry and ranges in capacity from 4.5kWh to 12kWh. The system’s size increases by adding 1.5kWh modules.

The new battery storage system is inclusive of Fronius Symo Hybrid inverter. It also includes the Fronius Smart Meter. The Smart Meter is specially designed to optimise self-consumption. It records the household’s load curve, too, delivering a high degree of flexibility in applications.
