A crisp January morning in 2019 marked the inception of a personal revolution as I embraced renewable energy with a 5 kWp solar panel installation and a home battery system. The evolution continued that September, when my driveway welcomed the futuristic silhouette of a Tesla Model 3 Performance, a testament to innovation and sustainability. It then transformed into a Model Y Performance, a vehicle that married comfort with eco-conscious engineering. Yet, this journey was not just about acquiring technology; it was a voyage into the heart of energy autonomy.
At the core of my renewable setup beats the sonnen eco 9.43 battery, produced by the renowned German manufacturer. Initially designed with a 10kWh capacity, it now boasts an impressive upgrade to 15kWh, with 13.8 kWh of usable power. Although its 3.3 kW output might not rival cutting-edge standards, it offered ample capacity to support a self-consumption mode—capturing the sun’s generous rays during the day to stave off the grid’s demand at night.
Charging my Tesla involved a dance between convenience and cost-effectiveness. The home wall charger, a relic of a time when Tesla gifted them alongside their cars, provided the means. Yet the allure of free local chargers proliferated in the vicinity: three 11 kW destination chargers complemented by a robust 50 kW NRMA DC charger. My electricity bill, meanwhile, shrunk from a staggering $2,600 annually to a mere $750—a testament to the savings power of renewable energy coupled with smart technology.
Embracing the broader network of Virtual Power Plants (VPPs), I partnered with sonnen’s VPP option, further slashing my expenses. But as electric vehicles transitioned from curiosity to ubiquity, the once-abundant free chargers dwindled. Suddenly, my VPP’s cap became a limitation, as surpassing its 7500 kWh annually ushered in exorbitant costs.
Faced with this conundrum, I uncovered Amber Electric, an innovative retailer offering wholesale energy market exposure for a flat monthly fee. The dynamic tariffs of the National Energy Market replaced static costs with electrifying opportunities—and pitfalls. Navigating this volatile market to optimize my energy use and battery management required ingenuity. Yet, sonnen’s systems weren’t open to outsider manipulation.
Necessity ushered me towards creating a custom solution, crafting a bespoke system with Home Assistant to take full advantage of real-time market fluctuations. This was modern energy alchemy, transforming sunlight into substantial savings.
On this path, I discovered EMHASS, an open-source addition that could weave solar forecasts and energy tariffs into a harmonious symphony of efficiency. With its help, I orchestrated my home’s energy use down to the second, ensuring not only that my electric vehicle thrummed with power, but that my entire household basked in the glow of energy independence.
The takeaway from my odyssey extends far beyond technology. Mastering the art of load shifting, I reshaped the energy landscape of my home, even swapping gas heating for efficient reverse cycle air conditioning, allowing for further annual savings. As the sun sets on my gas hot water and stovetop, the promise of a fully renewable fortress lies on the horizon.
This journey from a curious consumer to an energy virtuoso underscores a fundamental shift: every homeowner can become a guardian of their own energy future, crafting their path toward sustainability with creativity and commitment.
