When Hurricane Ian came ashore in Southwest Florida in September 2022, it knocked out power to millions of homes statewide, and some waited a week or more to get it back in September heat. Five years earlier, Irma had done nearly the same thing on a near-statewide scale. Florida has no single regional grid operator to borrow power from in a crisis — the lights here run through FPL, Duke Energy Florida, and TECO, and after a major storm every one of them faces the same slow, line-by-line rebuild. That’s the backdrop for the question almost every Florida solar shopper eventually reaches: are the panels enough, or do I need a battery too? If you’re still weighing the basics, start with our Florida solar incentives & costs guide.
Why your rooftop array goes dark with everyone else
Here’s the part installers tend to gloss over: a grid-tied solar system shuts itself off the moment the grid fails. It’s an anti-islanding safety rule that keeps your panels from pushing power onto lines a repair crew may be touching. So during the exact hurricane you bought solar to weather, an unbatteried rooftop array produces nothing — you sit in the dark alongside neighbors who never went solar at all. Storage is what closes that gap.
In Florida, size for the heat first
The load that defines a Florida outage isn’t lights — it’s cooling. Decide up front whether you only need to protect essentials or you want to keep air conditioning running, because that answer picks your unit.
For a fridge, Wi-Fi, phone charging, and a few lights over one to two days, the HomePower 3000 is the practical choice. At roughly 3,072Wh and 3,600W it covers the core of a home, runs near 30 decibels, is safe indoors because it vents nothing, and ships with solar panels that refill it during daylight — so it stretches across a multi-day outage instead of dying overnight.

If keeping central AC on through the worst of the heat is non-negotiable, step up to the Solar Generator 5000 Plus: 5,040Wh, 7,200W, both 120V and 240V, and expandable to 60kWh — enough to carry an air conditioner plus the rest of the house.

Buy before the cone points at you
The worst time to shop for backup power is when a system is already spinning in the Gulf or off the Atlantic coast and every store in the state is sold out. Set it up at the start of hurricane season and it’s charged and ready when the next storm forms. It’s worth checking the current deals before you need it.
