If you’ve already read What Is a Public Safety Power Shutoff?, you know the safety case against generators during wildfire conditions. This guide picks up from there with a more direct question: given every option on the market, ranked, which one should you actually buy? We’ve included one option that guide didn’t cover, using an EV as backup power, since it’s genuinely changed the landscape in the last year.
How We Ranked These
Four criteria, in order: safety during the specific conditions that cause a PSPS or wildfire evacuation (dry vegetation, wind, the need to leave quickly), usable capacity for real household loads, whether it switches on automatically or needs manual setup, and installed cost. See our full guide on how to prepare for California PSPS power shutoffs for the trigger conditions this ranking is built around.
#1: Whole-Home or Critical-Loads Solar Battery
Best overall. A home battery, ideally paired with solar, wins on every safety criterion that matters during wildfire conditions: no exhaust, no fuel, no fire-spark risk, and it can be left running unattended if you need to evacuate. It switches on automatically within milliseconds of a grid outage. According to 2026 EnergySage data for California, a typical 13 kWh system installed runs $11,864 to $16,052. The tradeoff is cost, this is the most expensive option upfront, though it’s also the only one that keeps working, and keeps recharging, for as long as a multi-day PSPS event lasts.
#2: EV with Vehicle-to-Home (V2H) Backup Power
Best if you already own, or are shopping for, a compatible EV. This is the newest entry on this list, and it’s a legitimate one now. A modern EV battery holds roughly 60 to 130 kWh, compared to 13 to 15 kWh for a typical home battery, meaning a single charged EV can carry the equivalent of five or more Powerwalls. The Ford F-150 Lightning’s Intelligent Backup Power system can deliver up to 9.6 kW continuously, enough to run a home for two to three days on a full charge. Kia’s EV9, GM’s Ultium lineup (Silverado EV, Blazer EV, Equinox EV, and others), and Tesla’s Cybertruck via Powershare all support similar setups with the right hardware.
Two real caveats worth knowing before counting on this option: first, it requires a bidirectional charger and, for most systems, a transfer switch or home integration panel, running roughly $3,500 to $8,000 installed depending on the vehicle and hardware, Tesla’s Cybertruck Powershare tends to be the cheapest path in. Second, the market is moving fast and not always forward: Ford discontinued its Charge Station Pro, the hardware new Lightning home-backup setups depended on, in 2026. If you’re considering V2H, verify current hardware availability for your specific vehicle before assuming a past review still applies.
#3: Portable Power Station (With a Solar Panel Add-On)
Best budget option, or a solid backup-to-the-backup. A large battery pack with built-in outlets, typically 1 to 3 kWh, running $300 to $2,000 depending on capacity. Safe in terms of fire and carbon monoxide risk, and genuinely portable, you can take it with you if you evacuate, which nothing else on this list offers. The real limitation is capacity and manual operation: it doesn’t wire into your panel, doesn’t switch on by itself, and without an add-on solar panel it can’t recharge once depleted during an outage. Good for a single room, medical device, or as a mobile supplement; not a substitute for whole-home coverage during a multi-day event.
#4: Gas or Propane Generator, Use With Real Caution
Ranked last specifically for wildfire conditions, not because it doesn’t work. A generator offers real power and relatively low upfront cost, $500 to $5,000 depending on size, but it’s the only option on this list with a documented death toll attached to its use: the CPSC links portable generators to more than 100 carbon monoxide deaths a year, and PGMA-referenced safety guidance requires a 5-foot cleared radius around the unit specifically because hot engine surfaces can ignite dry vegetation, the exact conditions present during a PSPS. It also can’t be left running safely if an evacuation order arrives. We cover both risks in detail in What Is a Public Safety Power Shutoff? If you already own a generator, that guide covers how to use it as safely as possible; it’s not a reason to avoid backup power altogether, just a reason to rank it last among the real alternatives.
FAQs
What’s the safest backup power option during wildfire season?
A whole-home or critical-loads battery, ranked #1 above. Among the four real options, it’s the only one with no exhaust, no fuel storage, no fire-spark risk, and no manual intervention required if you need to evacuate suddenly.
Why are generators risky to use during a wildfire evacuation warning?
Two documented risks: carbon monoxide poisoning, linked to over 100 deaths a year by the CPSC, and fire ignition from hot engine surfaces near the dry, windy conditions that define PSPS-triggering weather. A running generator also can’t be safely abandoned if an evacuation order arrives, unlike every other option on this list.
Can a home battery system run air filtration during smoke events?
Yes. A HEPA air purifier typically draws 40 to 100 watts, a small addition on top of a critical-loads setup already running your refrigerator and communication devices. An EV in V2H mode has even more headroom given its much larger capacity.
How does whole-home battery backup compare to portable power stations?
Home batteries hold roughly 5 to 10 times the capacity, wire directly into your panel to switch on automatically, and recharge from solar during an outage. Portable power stations are cheaper and genuinely portable, useful if you evacuate, but they’re a single-room supplement, not whole-home coverage. An EV with V2H sits above both in raw capacity but requires dedicated hardware most homes don’t yet have installed.
What backup power systems does HomeLink Solar install for wildfire season?
HomeLink Solar (CSLB License #1117534) designs solar-plus-battery systems sized around your household’s actual critical loads and California wildfire risk, with owner Mandy personally overseeing every install and no subcontractors. See real completed installs on our our installs page, explore no-large-upfront-cost options through our Power Choice Program, or get a free personalized quote.
What is the best backup power solution for home emergencies?
For most homes in wildfire and PSPS areas, a solar-plus-battery system sized around your critical loads is the best fit. It switches on automatically and has no fuel, exhaust or fire-spark risk. A portable power station covers small needs, an EV with vehicle-to-home (V2H) works if you already own a compatible one, and a generator is the last resort because of carbon monoxide and fire risks.
What battery is best for home backup?
No single battery is best for every house. Compare usable capacity (kWh), continuous power (kW), whether it can start big loads like an AC, warranty, and whether a local installer will service it. HomeLink installs Tesla Powerwall and Franklin batteries. See our side-by-side battery comparison for the specs.
How does using an EV for home backup compare to a home battery?
An EV battery is much bigger, about 60 to 130 kWh against 13 to 15 kWh for a typical home battery. But it needs a compatible EV, a bidirectional charger and usually a transfer switch or integration panel, around $3,500 to $8,000 installed. The car also may not be home, and running the house uses range you may want for driving. A home battery stays put, recharges from your solar, and switches on automatically.
How much does it cost to connect a backup generator, and will it stop a PSPS outage?
A generator can’t stop a PSPS. It only supplies power while the grid is off. To run your house safely it must connect through a transfer switch or interlock kit, so power can’t flow back into utility lines. A manual transfer switch typically costs about $400 to $1,300 installed (Angi, April 2026), and permit fees are often $80 to $450. That is on top of the generator itself, roughly $500 to $5,000. Check local permit rules first.
What combinations of home backup equipment work best in wildfire-prone areas?
A common setup is rooftop solar plus a battery sized for critical loads, so the battery recharges daily and keeps running through multi-day outages. Add V2H if you own a compatible EV, and keep a portable power station for small items. Keep a generator only as a last resort, used outdoors and away from the house.
What temporary power options exist during a PSPS?
SCE opens Community Resource Centers and mobile Community Crew Vehicles during PSPS events. They offer outage information, water, light snacks, resiliency kits, and charging for phones and portable medical equipment. SCE posts open locations on its Outage Map, usually a day before, and not every contracted site opens. These are short-term help, not a way to run your home. SCE lists cooling centers separately for heat.
What does a turnkey battery backup install include?
One contractor handles the whole job: free quote, custom design around your critical loads, permits filed, install day, and system activation. HomeLink does it with our own in-house crews and no subcontractors, so one team is accountable from design to power-on.
How do home battery, EV, portable station and generator backup compare on capacity and cost?
– Home battery: 13 to 15 kWh typical, about $11,864 to $16,052 installed in California for 13 kWh (EnergySage, 2026).
– EV with V2H: 60 to 130 kWh, plus $3,500 to $8,000 for V2H hardware.
– Portable power station: 1 to 3 kWh, $300 to $2,000.
– Generator: $500 to $5,000, plus fuel and transfer switch costs.
Do solar panels work during a power outage?
Not by themselves. Standard grid-tied solar shuts off during an outage for utility worker safety. With a battery and backup setup, your panels can keep running and recharge the battery during the day.
