The grid goes down for more than hurricanes

Storm season gets the headlines, but the power cuts out here for all kinds of reasons — and a battery doesn't care which:

  • Hurricanes & tropical storms. The big ones — but far from the only ones.
  • Severe thunderstorms & lightning. The most frequent culprit here, spring through fall.
  • Winter & ice storms. Less common on the coast, but they hit hard when they land.
  • Heat-driven grid strain. Summer demand peaks can push the grid past its limit.

What a battery does about it

When the grid drops, a whole-home battery system — wired to a smart electrical panel — takes over automatically and keeps your essentials running: fridge and freezer, Wi-Fi, medical devices, a sump pump, a window AC. It's backup insurance: it covers what you size it for, for as long as the charge lasts, then recharges from the grid or solar. The question to answer is simple: what do you want to keep running, and for how long? Run your bill and we'll show you what a right-sized system covers — and tell you plainly if it isn't worth it.

An honest caveat for the big ones. A battery covers an outage up to its capacity — hours to a day or more, depending on size and what you run. That handles the outages you get most. But in a major, multi-day event it will run down, and with the grid out you'd recharge it from solar (if the sun's out) or a generator. Plenty of people who want to ride out anything pair the two: the battery for instant, silent, automatic backup, and a generator to top it back up over a long haul.

More depth: what a battery keeps running and battery vs. generator.
