Franklin aPower
The Franklin aPower is a newer whole-home battery system gaining positive reviews. It prioritizes whole-home backup during outages, boasting a 10 kW peak and 5 kW continuous power output. It requires the Franklin aGate smart energy management unit, which allows charging from solar, the grid, or a generator. A key advantage is its scalability, allowing you to connect up to 15 aPower units for a massive 204 kWh of storage. However, this expandability and whole-home focus come at a higher price compared to some other battery options. Essentially, the Franklin aPower offers a robust, scalable solution for those prioritising extensive backup power and willing to invest in it.
While the Tesla Powerwall often leads the conversation, it’s not the only option. As we’ve explored, several compelling alternatives exist, each with its own strengths and weaknesses. From the scalable Franklin aPower for whole-home backup to the versatile Enphase IQ Battery for optimizing solar usage and the reliable LG Chem RESU 10H offering a balance of performance and cost, Australians have a range of choices. Ultimately, the “best” battery depends on your specific needs and budget. Consider your energy consumption, backup power requirements, and long-term goals. Don’t hesitate to consult with qualified solar installers to get personalized advice and make an informed decision. Taking control of your energy future is an investment in both your home and a sustainable future.
