Phoenix spent the summer of 2023 under a record that still sounds unreal: 31 straight days at or above 110°F. Now picture the grid dropping out in the middle of that streak. Arizona doesn’t belong to a regional grid operator the way Texas leans on ERCOT or the Mid-Atlantic leans on PJM — APS, SRP, and Tucson Electric Power each run their own system on the Western grid, and a monsoon haboob or microburst can knock a neighborhood offline in minutes. When that happens during a heat wave, the only question that matters about backup power is blunt: can it keep something cold running? If you’re already comparing Arizona solar quotes, note that a grid-tied rooftop array shuts off the instant the grid fails (anti-islanding safety rules), so panels alone won’t help mid-outage unless you pair them with storage.
That’s the job a Jackery solar generator does. The three HomePower units below solve three different versions of the same problem, from keeping a Mesa fridge alive to running central AC in a Scottsdale house. Here’s how they compare.
| Model | HomePower 3000 | 3600 Plus | 5000 Plus |
|---|---|---|---|
| Capacity | ~3,072Wh | 3,584Wh | 5,040Wh |
| Output | 3,600W | 3,600W | 7,200W |
| Expandable to | Not expandable | 21kWh | 60kWh |
| Runs central AC | No | No (window AC yes) | Yes |
| 240V | No | No | Yes |
| Best for | Fridge + Wi-Fi + lights, 1–2 days | Essentials + a window AC | Whole home, central AC |
Reading the table for a Phoenix summer
The line that decides everything is “Runs central AC.” Only the Solar Generator 5000 Plus clears it: 5,040Wh of capacity, 7,200W of output, both 120V and 240V, and expandable to 60kWh. That’s the surge and split-phase voltage a central air handler and condenser need to start and keep running. For a larger north Phoenix or Scottsdale home where losing the AC in July isn’t survivable for an older resident or a pet, this is the unit to size around.

If you only need to keep one room livable — a bedroom cool enough to sleep through a monsoon-season outage — the HomePower 3600 Plus is the flexible middle. It offers 3,584Wh and 3,600W, expands to 21kWh, and ties into your home’s circuits through a transfer switch, so it can carry the essentials plus a window or portable AC without wiring in a whole-home system.

And if the goal is simply to protect the fridge, Wi-Fi, lights, and a fan or two, the HomePower 3000 covers those essentials for one to two days and ships with solar panels that refill it in Arizona’s near-constant sun — so it keeps going even if APS or SRP takes longer than expected to restore. It can’t run central AC, but for a Tucson apartment or a smaller Chandler home it’s the value pick.

Don’t wait for the next haboob
Monsoon storms arrive fast and sell out backup power just as fast. Charged and sitting in a closet before the season, any of these three is ready the moment the lights flicker. It’s worth checking the current deals before you need one.
