Riding Out a Multi-Day Outage, at a Glance

Most outages are short, and a battery sails through them. The honest test is the multi-day outage, because a battery holds a finite charge that a long wait can outlast. You stretch it by shedding heavy loads — central air, electric heat, an electric range, a well pump — running only essentials, cycling loads, and keeping the fridge and freezer closed. During an outage a battery can only refill from solar, in daylight, so for the truly long wait a generator is the honest partner, with the battery covering the quiet hours. There's a printable 29-page version up top.

Common Questions

1 How long will a home battery last in an outage?

It depends on your capacity and exactly what you're running, so I won't guess a number. On light essentials it stretches; on heavy loads it empties fast. A licensed installer can size it to your real must-run list.

2 Can the battery recharge while the power is out?

Only from solar, and only in daylight — nothing overnight, and less on a gray day. With no solar, it can't refill until the grid returns, so plan a long outage around that limit.

3 What should I turn off to make a battery last longer?

Shed the heavy loads first: central air, electric heat, an electric range or water heater, and a well pump running non-stop. Run only your essentials and cycle them in turns.

4 Do I need a generator as well as a battery?

For the truly long, multi-day outage, a generator is the honest partner — it runs on fuel for endurance while the battery brings silence and an instant handoff. Many homes pair the two.

5 I'm on a well — what happens to my water?

The pump stops when the power does, and a battery may run it only in bursts. Store drinking water ahead of storm season, and keep some for flushing — it's your surest bridge.

6 Does keeping the fridge closed really help?

Yes. A closed fridge or freezer holds its cold for a good while, so the battery only has to nudge it now and then. Open the doors as little as possible during a long outage.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
