A practical framework for choosing between a fuel generator, a portable power station, and a home battery, by outage length, budget, and safety.
Home Backup Power
The day the power goes out, the advice online is loud and usually trying to sell you a specific box. KnowDepot’s home backup power guides do the opposite: we explain how the technology actually works so you can size and choose it yourself. Watts versus watt-hours, surge versus continuous load, gas generator versus battery versus whole-home storage, what runs indoors safely and what doesn’t. We read manufacturer documentation, government safety and energy guidance, and the hard-won experience owners share, then reconcile it into clear decisions. We’re honest about the math vendors gloss over, and about where credible sources disagree. We don’t publish payback promises or savings figures, and we send anything involving panel wiring or medical devices to the right professional. Enough understanding to buy once and buy right.
Most rooftop solar shuts off the instant the grid fails. Here is why anti-islanding does that, and what setup actually keeps your lights on in an outage.
How long food lasts in the fridge and freezer during a power outage: the FDA and USDA 4-hour rule, 48-hour freezer rule, and a keep-or-toss chart.
During a multi-day storm, solar input can collapse to single digits. Here is what realistically recharges a power station, and in what order.
A decision framework for choosing what to back up in an outage: build an essential-load list, tier it by need, and right-size your gear.
Why portable generator carbon monoxide kills without warning, the CPSC 20-foot rule, CO alarms, UL 2201 shutoffs, and why battery stations are safe indoors.
Rated watt-hours overstate usable runtime. How inverter loss, idle drain, cold, aging, and motor surge shrink it, plus an honest sizing method.
Rolling blackouts and storm outages differ in duration, warning, and frequency. Here is how each scenario should shape what you back up at home.
A pre-storm backup power checklist and 72-hour timeline: build your essential-load list, top up power and fuel, and stage supplies before a storm.
Why a power station rated for 2000 watts still cannot run a space heater, window AC, or well pump, and how surge and continuous loads differ.
Watts measure power, watt-hours measure capacity, and confusing the two is why a power station disappoints. How to size one correctly, explained.
