A summer microburst can slam out of a Nevada sky and drop a Las Vegas or Henderson neighborhood off the grid in seconds: no real warning, no storm that lasted more than twenty minutes, just downed poles and a dark house in 108°F heat. NV Energy runs the grid across most of the state, with Valley Electric Association serving Pahrump and pockets out west. When the power goes in that heat, the danger is not discomfort: it is how fast a closed-up house climbs toward unsafe for older residents, small children, and pets. If you are already comparing Nevada solar quotes, it is worth knowing what installers rarely lead with: a grid-tied rooftop system shuts off during a blackout (anti-islanding rules) unless you also have storage. The cooling-first pick for Nevada is the Jackery Solar Generator 5000 Plus, and the rest of this guide explains why and when a smaller unit is enough.
Two real Nevada outages, two different causes
The first is a heat-season outage. On Tuesday 1 July 2025 a dry microburst (rain evaporating before it reaches the ground, so the cooled air drops and spreads out fast) pushed gusts of up to about 70 mph across the Las Vegas Valley. More than 33,000 NV Energy customers lost power within minutes, nearly 50 poles were reported damaged in the first hours, and about 70 poles were eventually replaced. NV Energy reported all affected customers restored by 9am on Friday 4 July, which means some households spent most of three days in early-July heat on a repair queue. Nothing about the storm was unusual for Nevada summers. That is the point.
The second is a wildfire outage, and it hit the north of the state. On the evening of Saturday 22 August 2026, the Hawk Fire on Peavine Peak ran toward homes in northwest Reno. As the fire approached its equipment, NV Energy made an emergency decision to cut power, de-energizing more than 60,000 customers in northwest Reno and the North Valleys at about 6pm. Power returned for roughly 50,000 of them soon after midnight, but several thousand customers stayed dark while crews rebuilt about 100 damaged or destroyed utility structures. NV Energy has since issued Public Safety Outage Management watches for 13 areas of Northern Nevada, warning that power may be shut off on purpose in high wind and fire weather. A shutoff you were warned about is easier to prepare for than a storm, but only if the battery is already charged.
Two different parts of the state, two different triggers (wind, then wildfire), and both left customers with no say in when the lights came back.
Start with the cooling load, not the battery
In most states you size backup power around the fridge. In Nevada you size it around the air conditioner, then add the fridge. Reno and the high desert cool off at night, so a single unit that runs an AC for a few evening hours often gets a home through. Down in Las Vegas and Henderson, where overnight lows can stay in the 80s, the cooling has to keep going far longer, which usually means more capacity.
Size against energy used per day, not the wattage printed on the box. These are typical figures; your own appliances will differ, so check the label on each.
| Load | Typical draw | Energy per day |
|---|---|---|
| Fridge/freezer | ~150W running (cycling) | ~1,200Wh |
| Wi-Fi router | ~10W | ~240Wh |
| LED lights (ten bulbs) | ~50W | ~300Wh (6 hrs) |
| Phone and laptop charging | ~20 to 60W | ~150 to 250Wh |
| Fans (two or three) | ~50 to 150W | ~600 to 1,800Wh |
| Window or portable AC | ~900 to 1,200W while running | ~4,000 to 6,000Wh |
| Central AC (240V) | ~2,000 to 3,500W | ~8,000 to 14,000Wh |
Fridge, lights, Wi-Fi, and phones add up to roughly 1,900 to 2,000Wh a day. Here is how long each unit lasts on its stored charge alone, before any sun comes back, allowing for about 15% lost in conversion.
| Unit | Stored energy | Essentials only (~1,950Wh/day) | Fridge alone | A window AC cycling (~700W average) | Central AC cycling (~1,500W average) |
|---|---|---|---|---|---|
| HomePower 3000 | 3,072Wh | about 1.3 days | about 2 days | about 3.5 hours | not suited (cannot start it) |
| HomePower 3600 Plus | 3,584Wh | about 1.6 days | about 2.5 days | about 4.5 hours | not suited (cannot start it) |
| Solar Generator 5000 Plus | 5,040Wh | about 2.2 days | about 3.5 days | about 6 hours | about 3 hours |
The takeaway: a battery alone carries the fridge and lights for a couple of days, but anything that cools a room drains it in hours. In Nevada that is not a reason to give up on batteries, because the sun that causes the heat is also the best recharge you will ever get. A few hundred watts of panels refilling in the afternoon turns hours into days, and a battery that cools one bedroom overnight does more for safety than one that tries to hold the whole house at 74°F.
Sizing a solar generator to your Nevada home
Start with the heaviest load you care about, then work down. If you want central air to keep running through a Las Vegas summer outage, only the Solar Generator 5000 Plus has the output for it: 5,040Wh of capacity and 7,200W with both 120V and 240V, expandable to 60kWh. That is enough to start a central system and carry several rooms at once, which makes it the unit to consider for a larger home that needs cooling through a July outage.

For many Reno and Henderson homes, cooling one room is enough to ride out the night. The HomePower 3600 Plus (3,584Wh, 3,600W, expandable to 21kWh, and able to tie into your circuits through a transfer switch) runs your essentials plus a window or portable AC without a whole-home install. See the HomePower 3600 Plus specs and price at Jackery.
And if you just want the fridge, Wi-Fi, lights, and a fan protected for one to two days, the HomePower 3000 is the lowest-priced of the three, with about 3,072Wh and 3,600W output. It ships with solar panels, and in Nevada’s near-constant sun it recharges mid-outage, so it can last as long as the outage does. It will not run central AC, but it keeps the core of a home alive. Check the current price of the HomePower 3000 (panels included).
| Unit | Capacity / output | Best for in Nevada |
|---|---|---|
| HomePower 3000 | 3,072Wh, 3,600W, panels included | Fridge, Wi-Fi, lights, and fans for one to two days |
| HomePower 3600 Plus | 3,584Wh, 3,600W, expandable to 21kWh | One cooled room plus essentials through a windstorm outage or a fire-weather shutoff |
| Solar Generator 5000 Plus | 5,040Wh, 7,200W, 120V/240V, expandable to 60kWh | Central AC on 240V, or a larger home that needs several rooms cooled |
Solar versus a gas generator in the heat
The heat that follows a Nevada outage is the real hazard, and that is where fuel-burning generators fall short. Every one of these Jackery units is LiFePO4, runs near 30 decibels, and produces zero exhaust, so it can run in a sealed, cooled room and be stored in a closet in a Boulder City or Pahrump house between outages as long as it is kept charged.
- Indoor safety and carbon monoxide. A battery station vents nothing and can run with the house closed up against the heat. A gas generator has to run outdoors, well away from windows.
- Noise. About 30 decibels versus the 60 to 90 a gas generator runs at.
- Fuel. The battery is charged before the event and refills from the sun after. During the Hawk Fire, roads near the burn area were closed, and a fire or a downed-pole cleanup can shut the route to the nearest working station.
- Wildfire risk. A running gas generator is a hot engine and a fuel can in dry brush country. Shutoff watches in Northern Nevada come precisely on high-wind, high-fire-danger days.
- Maintenance. Oil, carburetor, and monthly test runs for gas. A monthly top-up for the battery.
- What gas still does better. A very long outage with no sun, and whole-house 240V at a lower upfront cost.

Set-up checklist before summer and fire season
- Charge to full and top up monthly. Do it again when NV Energy issues a shutoff watch for your area.
- Keep it indoors in a closet, garage, or utility room, away from direct heat. A garage in a Las Vegas July can be hotter than the battery likes, so a shaded interior spot is better.
- Write down which loads go on it. Fridge, one window or portable AC, router, fans, one lamp per room. Tape the list to the unit.
- Buy extension cords rated for the load. A short 12-gauge cord for the fridge and AC runs.
- Test the AC on the battery once before July, so the first time is not during an outage.
- Keep the panels accessible for daylight recharging, and aim them when the sun is strongest.
- Pair the HomePower 3600 Plus with a transfer switch for hardwired circuits. Licensed electrician only.
- Pick your cool room now. The smallest interior room with a door that closes is the cheapest to keep safe.
- Keep a battery-powered CO alarm regardless. A neighbor’s gas generator can still put CO in your house.
If you are not sure which size fits, list what must stay on, add up the wattage, and match it to a unit with room to spare.
