The best solar generator for home backup, picked on solar input limits, voltage window, expansion and recharge days in winter sun, with the calculations shown.

On this page

The short answer

Our pick at PreppedPower for a solar generator for home backup is the Jackery Explorer 5000 Plus. It accepts the most solar power of these three, has a separate high-voltage input for long panel strings, and stores the most energy, so a sunny day can carry the house through the night. The Anker SOLIX F3000 is the smaller entry point with its own high-voltage solar input, and the Bluetti Apex 300 has the longest-rated battery life and 120/240 V from a single unit. In winter, the solar input limit matters as much as the battery: a station that caps its input wastes the panels you add past that point.

What a solar-backed outage day needs from a power station

One day of reference loads

≈ 4330 Wh

rated capacity · calculated

The reference loads use 3,680 Wh/day. At 85% usable energy, this requires about 4,330 Wh rated capacity per day, before solar. Standby draw and actual cycling can change this estimate. These are reference inputs for a winter outage, not measurements of your appliances: the furnace blower is counted for about four hours a day. Solar recharge assumes a large array and short winter days; your local sun hours decide the real figure.

Reference loads

  • Refrigerator: 400 W running ; 1,200 W starting ; 1,200 Wh/day; 120 V
  • Gas furnace blower (1/2 hp): 500 W running ; 1,600 W starting ; 2,000 Wh/day; 120 V
  • Router and modem: 20 W running ; 480 Wh/day; 120 V

920 W known simultaneous load; 3,680 Wh/day calculated using stated daily energy or 8 running hours per day.

Energy-only loads do not establish output compatibility. Check each motor's start demand; this model assumes one motor starts at a time.

The maths, shown

Every runtime here is calculated from rated capacity. Here is the first pick, step by step.

5,040 Wh rated × 0.85 ÷ 3,680 Wh/day = ≈ 1.2 days calculated coverage, before solar.

Daily energy uses each explicit dailyWh, otherwise runningW × 8 hours/day. Output and surge checks use running watts separately.

Before you buy

Solar panels connect to the station's own solar inputs. Getting the station's power into your home circuits is a separate step: a power inlet with a panel interlock, a listed manual transfer switch, or the brand's own home panel, installed by a licensed electrician. Never backfeed a house through a wall outlet.

Read our connection and power-station safety guidance before connecting home circuits.

Questions

What is a solar generator?

A battery power station paired with solar panels. There is no engine and no fuel: the panels recharge the battery, and the station's inverter powers your appliances. Size the battery to your loads and the panels to the station's solar input limit.

How many solar panels do I need for home backup?

Start from the energy you use per day. Divide it by your location's peak sun hours and by 0.86 for typical system losses (NREL's PVWatts default) to get the panel watts that would replace it. Then check the station's maximum solar input: panel watts above that limit add nothing. PVWatts gives sun hours for your address, and winter figures are much lower than summer ones.

What does the solar voltage window mean?

Each solar input accepts a range of panel voltages, shown in the table. Panels wired in series add their voltages, so the string's open-circuit voltage has to stay inside that range. Open-circuit voltage rises in cold weather, so leave margin below the top of the window. A high-voltage input lets you run longer strings with less current.

How long does solar take to recharge one of these in winter?

The table's recharge days are calculated, not measured: our reference array and winter sun hours, capped at each station's solar input, minus the reference loads the house uses that day. Cloudy days, panel angle, shade and snow cut that output, so treat the result as a best case for clear weather.

Will my rooftop solar charge a power station during an outage?

Usually not. A standard grid-tied rooftop system shuts down when the grid goes down so it can't send power onto lines that crews are working on. Unless your system was designed with backup capability, the panels that charge a portable station during an outage are the portable ones you connect to it directly.

Can I claim the federal solar tax credit for a solar generator?

Not for new purchases. The IRS says the residential clean energy credit (25D) is not allowed for expenditures made after December 31, 2025, and an expenditure counts as made when installation is complete. Some brand pages still advertise a 30 percent credit; we don't repeat that claim. Check DSIRE and your utility for state or local incentives.
