Two years years ago, Greg had a 6.6kW system installed on his new home in Applecross. Wanting a top-quality system, he chose SunPower Performance solar panels and a 5kW Fronius Symo inverter.

Fast-forward 2 years, Greg decided it was time to add a battery, but unfortunately the original solar company was no longer in business. So instead, he contacted SunPower Australia directly and asked to be referred to a local SunPower partner. Positive Energy Solutions came recommended as “The Best in the West“

After analysing Greg’s energy usage data, we determined that the existing 6.6kW system simply wasn’t big enough to cover his high daytime power usage and also fully charge a battery. Not to mention, the existing Fronius Symo inverter was the older non-hybrid model i.e. not “battery-ready”. So what was the plan…

To provide the extra power needed, we installed an additional 8.6kW of All-Black SunPower Performance panels to match the existing SunPower panels. And rather than replacing a perfectly good inverter, we installed a 2nd inverter instead – the latest Fronius GEN24+ hybrid model. 

By sticking with Fronius as the inverter brand, both the new and old system work together cohesively and are monitored online as one. Solar power from both sets of solar panels are used to charge the 16kWh BYD battery.

Greg is now the proud owner of a 15.2kW system. This Solar & Battery installation in Applecross can produce an average of 60 kWh per day, and even more in Summer; plenty for running the air-conditioner freely. The system is also ready to provide Backup Power in the event of a grid-outage.
