The verdict: the Jackery Solar Generator 5000 Plus is the unit to buy when the appliance you cannot lose runs on 240V. That means a rural home on a well, a house in Phoenix or Houston where losing central AC in August is a safety problem, and anyone with an electric water heater on the must-keep list. Its 7,200W output on 120V and 240V starts those loads, its 5,040Wh carries the essentials for about two days on its own, and it expands to 60kWh. If your list is the fridge, Wi-Fi, lights, phones, and a CPAP, buy the HomePower 3000 and keep the difference. If you need a gas furnace blower through a long winter outage and nothing on 240V, the HomePower 3600 Plus is the better buy.
The rest of this page shows the working, so you can check it against your own house before you spend anything.
Why 240V and 7,200W are the whole point
Two specs change what a battery can do at all; everything else on this unit is a bigger version of the smaller Jackerys.
240V is the reason the 5000 Plus exists. A well pump, central AC, an electric water heater, an electric dryer, and a heat pump are wired for 240V, and no 120V-only unit will run them, however large its battery. The 5000 Plus supplies both voltages, so the unit that runs the fridge on a cord also runs the well pump through a transfer switch.
7,200W is what makes that 240V outlet useful. Motors do not start at their running wattage. A well pump that draws about 1,000W running pulls 2,000 to 3,000W for a second or two as it spins up. Central AC draws 3,000 to 4,000W running and surges above that at every compressor start. A 3,600W unit can stall on those surges even when the running load looks fine on paper. At 7,200W the 5000 Plus starts them with headroom for the fridge and lights alongside.
Together they cross a line the smaller units cannot: this one can carry a house’s hardwired circuits, not just what plugs into a wall.

What it runs, and for how long
Capacity, 5,040Wh, is the size of the tank; output, 7,200W, is how big a load it can run at once. Every runtime below is on battery alone with no sun and nothing else plugged in. The last column is the same load at full expansion to 60kWh.
| Load | Typical draw | Energy used | On 5,040Wh alone | At 60kWh |
|---|---|---|---|---|
| Refrigerator or fridge-freezer | ~150W running | 1,000 to 1,500Wh a day | 3 to 5 days | 40 to 60 days |
| Chest freezer | ~100W running | 600 to 900Wh a day | 5 to 8 days | Two months |
| Wi-Fi router and modem | ~10W | ~240Wh a day | About three weeks | Months |
| Ten LED bulbs | ~50W | 50Wh an hour | About 100 hours | Weeks |
| Phones and a laptop | ~20 to 60W | 150 to 300Wh a day | 2 to 4 weeks | Months |
| CPAP (no heated humidifier) | 30 to 60W | 300 to 500Wh a night | 10 to 16 nights | Months |
| Gas furnace blower and ignition | 400 to 600W running | 3,000 to 5,000Wh a day in deep cold | A day to a day and a half | 12 to 20 days |
| Small window AC | 400 to 600W | 4,000 to 8,000Wh a day | 15 hours to a day | 7 to 15 days |
| Sump pump (1/3 hp) | ~800W running, higher to start | Depends on the rain | Starts it; ~130Wh per ten minutes | Any storm |
| Well pump (240V) | ~1,000W running, 2 to 3x to start | An hour of pumping a day is ~1,000Wh | Starts it; about 5 days of normal use | Weeks |
| Electric water heater (240V) | Large; check the nameplate | Depends on use | Starts it; heat water in short bursts | Days of showers |
| Central AC | 3,000 to 4,000W, big surge | 20,000Wh and up a day | ~1.5 hours of compressor time; a few hours of cooling | 2 to 3 days |
| Electric space heater | 1,500W | 1,500Wh an hour | About three hours. Do not plan on it | A day or two |
Three lines deserve a second look. The well pump costs less energy than the fridge, because normal household use is a few dozen minutes of pumping a day; what it needs is the 240V and the surge. The central AC line is the honest one for hot climates: the base battery buys a few hours of cooling, enough for the worst of an afternoon, not for a night, and expansion turns that into days. The space heater line is the same warning as on every battery: 1,500W drains 5,040Wh in about three hours.
Two days without the grid, on a well
Here is a two-day outage for a rural house with a fully charged 5000 Plus, the well pump on the transfer switch, and the essentials on the outlets: fridge, chest freezer, Wi-Fi, a few lights, phones.
Evening one. The power drops at 6 p.m. The well pump comes back through the switch, so taps and toilets work as normal. The first night costs about 1,700Wh: roughly 600Wh for the fridge over twelve hours, 400Wh for the freezer, 200Wh for four hours of lights, 120Wh for Wi-Fi, 100Wh of phone charging, and about 300Wh for twenty minutes of pump time across dishes, showers, and toilets.
Morning two. You have about 3,300Wh in hand and you set the panels out. Daytime costs about the same again: fridge 600Wh, freezer 400Wh, Wi-Fi 120Wh, phones 100Wh, and another 500Wh of pumping for showers and watering the animals. By evening you have used 1,700Wh more and the panels have put some back.
Evening two, if the day was bright. A clear summer day returns 1,500 to 2,000Wh, so you go into night two with roughly what you had on the first morning and wake on day three with more than a third of a tank. Nothing has been rationed.
Evening two, if the day was grey. A grey day returns a few hundred watt-hours, so you go into the second night with around 2,000Wh against a 1,700Wh night. You get through with a little to spare, but day three starts near empty: short showers, freezer shut, a headlamp for light, and the pump and fridge get everything that is left.
On the base 5000 Plus a house on a well keeps its water for two days with normal habits and three with careful ones. With expansion packs the trimming stops being necessary. The smaller Jackerys cannot run the pump at all.
Expansion and the transfer switch
The 5000 Plus starts at 5,040Wh and expands to 60kWh with add-on battery packs, the largest expansion of the three Jackery home units and what separates a two-day unit from a two-week one. Check the product page for pack sizes and how many the unit accepts.
Pair expansion with a transfer switch and the unit stops being a big power bank and becomes home backup. The switch sits beside your breaker panel and lets the 5000 Plus feed chosen circuits directly: the well pump, the furnace, the fridge circuit, the air handler. It is also the only way to reach the appliances a cord cannot; a well pump has no plug, and neither does most furnaces or a hardwired water heater.
Two rules, and neither has an exception. It must be fitted by a licensed electrician. Never backfeed a wall outlet with a cord from the unit; it can energise the line outside your house and kill the worker fixing it, and it is illegal almost everywhere.
Solar recharge, honestly
On a bright summer day, with the panels angled at the sun and moved once or twice to follow it, expect to put back 1,500 to 2,000Wh. Against a 5,040Wh battery that is a third of a tank a day: enough to keep the essentials and the well pump running indefinitely in good weather, not enough to carry central AC on its own. On a grey winter day, expect a few hundred watt-hours, which covers the router, the phones, and a few starts of the pump, not the fridge.
Treat those as a rough range; panel wattage, latitude, cloud, and shade all shift the number. Charge to full from the grid before a forecast storm, and set the panels out first thing in the morning.
What it will not do
Three things, said plainly.
- It is not a whole-house generator that runs everything for a week without sun. The base battery carries the essentials plus a well pump for two days, or central AC for a few hours. Running the house as if the grid were up, AC at 70°F and the dryer going, empties any battery fast. Choose the circuits that matter and size expansion for those.
- It is not small. A 5,040Wh battery with a 7,200W inverter is a substantial piece of equipment. Check the product page for size and weight and decide where it will live before it arrives: near the panel, indoors, above freezing.
- It will not outrun physics on a space heater. 1,500W of resistive heat costs 1,500Wh an hour on any battery. A gas furnace blower at 400 to 600W heats the whole house for a fraction of that.
None of those are faults; they are the boundaries of every battery in this class, and the 5000 Plus sits at the generous end of them.
5000 Plus vs HomePower 3000 vs 3600 Plus
The three Jackery home units solve three sizes of the same problem. Here is how they line up.
| Unit | Capacity / output | Best for | Buy |
|---|---|---|---|
| Jackery Solar Generator 5000 Plus (this review) | 5,040Wh · 7,200W · 120V/240V · expandable to 60kWh | Well pump, central AC, water heater, hardwired circuits | Check price → |
| Jackery HomePower 3600 Plus | 3,584Wh · 3,600W · expandable to 21kWh · transfer-switch ready · 120V | Essentials plus a furnace blower or window AC, multi-day outages | Check price → |
| Jackery HomePower 3000 | 3,072Wh · 3,600W · panels included · 120V · not expandable | Fridge, Wi-Fi, lights, phones, CPAP for 1 to 2 days | Check price → |
The 3600 Plus is the unit to weigh against this one if your must-keep list is all 120V. It is smaller at 3,584Wh and half the output at 3,600W, but it expands to 21kWh and is transfer-switch ready, so it handles a furnace blower and the essentials for days, for less.
The HomePower 3000 is the essentials unit: 3,072Wh, 3,600W, panels included, not expandable, 120V only. It is the right buy for a day or two of fridge, Wi-Fi, lights, and a CPAP, and the wrong buy for anyone reading a 240V review. Our full comparison of the three works through each.
Who should buy it, and who should not
Buy the Solar Generator 5000 Plus if:
- You are on a well. A house with no water is not a house you can stay in, and this is the smallest Jackery that runs the pump. Our well pump guide sizes it against pump horsepower.
- You live where losing central AC is a safety problem. The Phoenix guide and the Texas guide both land here.
- Your must-keep list includes an electric water heater, an electric dryer, or a heat pump.
- You want hardwired circuits through a transfer switch and room to grow to 60kWh.
Buy something else if:
- Your list is the fridge, Wi-Fi, lights, phones, and a CPAP, and your outages last a day or two. That is the HomePower 3000, panels included, for a good deal less.
- Your list is 120V plus a gas furnace blower, and you need more days rather than more volts. That is the HomePower 3600 Plus with expansion packs.
- You are shopping on price for 240V alone. Our cheapest 240V home backup guide lines this unit up against the Anker and EcoFlow kits.
Our best solar generators for home backup guide sets all three Jackery units against those kits, and the state-by-state backup guides size each unit against your own state’s outages.
