It’s all about the give and take when it comes to planning out your home battery storage solution. When designing your energy storage system, it is essential to find a balance between the total capacity of the Powerwall(s) with the demand of everything you need to power up. Each Powerwall can deliver up to 48 amps, and up to 4 Powerwalls can be connected side by side. However, even if there is enough amperage to cover all of your loads, we need to consider the pace of how quickly electricity will be drawn to maximize the effectiveness of your back-up system.
A common misconception is that your solar output will recharge your battery at the same rate you’re using it. This depends greatly on uncontrollable factors like weather and user consumption habits. An easy way to look at battery storage is to think of how driving tendencies vary by operator and by vehicle. You may be a more efficient driver of your new Prius while your cousin Karen drives a 2001 Jeep Wrangler like she’s running a desert race. Similarly, Powerwall performance will be dependent on user consumption tendencies and what you are powering up. A small, highly efficient home with energy efficient appliances might power more than a larger, older home with leaky windows. By monitoring your usage and storage abilities, you’ll gain greater insight into what you can power and how quickly your Powerwall might recharge.
Ultimately, to determine what’s best for you, we need to take a look at your average historic usage and discuss what you’re looking to get out of our battery storage.
