How Many Batteries Do You ACTUALLY Need to Power a House?

Описание: How many batteries do you actually need to power your house? I break down the exact 3-step formula so you can stop guessing and start sizing right.
Most battery sizing advice online gives you a national average and calls it a day. That's not how this works. Your house, your climate, your outage risk — they're all different. In this video, I walk through the three steps to figure out YOUR actual number, and then I match it to three real battery options with exact unit counts for both whole-home and essentials-only backup.
Batteries covered:
Tesla Powerwall 3 (13.5 kWh) | Enphase IQ Battery 5P (5 kWh) | FranklinWH aPower 2 (15 kWh)
