Recommended Solar Power Generator for Home Backup

Best Solar Generator for Home Backup: Sizing for Outages That Last

A solar generator is a battery, inverter and charge controller in one cabinet, with panels that refill it while the grid is down. It burns no fuel, runs silently indoors and starts the instant power fails. The best solar generator for home backup is the one whose watt-hours match how long your outages run and whose output matches the largest appliance you refuse to lose, whether that is a fridge, a sump pump or a 240V well pump.

This collection holds 190 configurations from Anker and Mango Power. A standalone Mango Power E with 3.5kWh starts at $1,299; bundles with expansion batteries, panels or a home power panel reach $5,300 for twin Anker SOLIX F3800 units at 12,000W and 7.68kWh.

How to choose a backup solar generator

• Hours of outage you plan for. Essential loads in a typical house (fridge, freezer, internet, lights, phone charging) run 3 to 5kWh a day. The Mango Power E 3,000W 7kWh Home Backup bundle covers about two days; the Anker SOLIX F3800 + BP3800 stores 7,680Wh for a similar window at double the output.
• 120V or 240V. Well pumps, electric water heaters and dryers need split-phase 240V. The Mango Power E 6,000W 7,060Wh 240V Kit with mSocket Pro pairs two stations for split-phase output; the F3800 delivers 240V from a single unit.
• Whole-house connection or extension cords. The 2 x Anker SOLIX F3800 Smart Home Power Kit adds the Home Power Panel so circuits switch over through the app; the Mango Power 14,120Wh kit includes the mPanel Pro for the same job. Simpler bundles power appliances plugged directly into the unit.
• Solar recharge. A home solar power backup generator only earns its name with panels. The F3800 accepts up to 2,400W of solar; the Mango Power E ships in a package with two 200W folding panels for buyers starting small.

Setup and usage tips

• Size before you buy with the Solar Kit Calculator. Enter the appliances you want running during an outage and your ZIP code; it returns the battery, inverter and panel numbers to compare against each bundle.
• Decide on the transfer method early. A home power panel or mPanel Pro is installed by an electrician once; extension-cord backup needs no install but limits you to what reaches the unit.
• Keep it plugged in. Any solar home backup generator should sit at full charge on grid power so it is ready when the lights go out.
• Place panels where you can reach them. Portable 200W panels stored in the garage can be set out on a driveway after a storm; rigid panels on a roof keep charging through the outage without attention.
• Expand storage, not output, for long outages. Adding a BP3800 to the F3800 doubles run time; the inverter rating stays 6,000W, which is already more than most homes draw at once.

Frequently asked questions

How big a solar generator for home backup do I need for a fridge and furnace blower? Together they draw around 2 to 4kWh a day. A 3.5kWh Mango Power E gets you through a night; the 7kWh bundle or the F3800 + BP3800 gets you through a weekend.

Can these run central air conditioning? A 6,000W, 240V unit such as the F3800 or the paired Mango Power E kit can start and run many residential condensers, but check your unit's locked-rotor amps and expect the battery to drain in a few hours.

Do I need panels on day one? No. Every station here charges from the wall. Add panels when you want a home backup solar generator to outlast a multi-day outage.

All bundles ship free to the mainland US from the brand partner warehouse, usually within a few business days, with 30-day returns. Call us if you want help matching a kit to your panel and circuit layout.
