Sizing a home battery in Tampa: what you actually want to back up
Battery sizing is a loads conversation, not a kilowatt-hour contest. Here's how to pick backed-up circuits for a Tampa home and what each one costs you.
The right question is not "how many kilowatt-hours" — it's "what do you want running when the power is out, and for how long."
Start with a loads list
Typical priority order for a Tampa home:
- Refrigerator and freezer
- Lights and outlets in a few rooms
- Internet and phone charging
- Well pump or sump, if you have one
- One air conditioning zone or a mini-split
- Whole-home cooling
Items 1–4 are cheap in energy terms. Item 5 is the jump. Item 6 is what turns a one-battery project into a multi-battery project.
Air conditioning is the whole conversation
A central air system in a Florida August can pull a substantial share of a single battery's usable capacity in a day. Backing up cooling is legitimate, but it should be a deliberate, priced decision — often the better answer is one backed-up mini-split in a bedroom rather than the whole house.
Solar changes the math
A battery alone gives you a fixed amount of energy. A battery paired with solar recharges every sunny day, which turns a one-night device into a multi-day one. In a Tampa hurricane outage, that difference is the point.
