Solar Backup Generators with Transfer Switch

Portable Solar Generator for Home Backup: Sizing for a Real Outage

A portable solar generator is a battery power station sold together with the panels that recharge it. During an outage it keeps the refrigerator, internet, lights, a sump pump or medical equipment running with no fuel, no exhaust and no noise, and the panels stretch that runtime as long as the weather cooperates. Compared with a gas unit, a solar backup generator starts the moment you press a button and can sit in a hallway closet, not the garage.

This collection contains 200 products from Anker and Bluetti. Entry points start at $899 for a 2,073.6Wh Bluetti Elite 200 V2, and the largest Anker SOLIX F3800 bundles reach 7,680Wh with rigid or portable panels for $4,799 to $4,999.

How to choose solar with backup generator capability

• Outage length you plan for. A few hours means any unit here works. A two or three day storm outage points to 6,000Wh and up: the Anker SOLIX F3000 + BP3000 Expansion Battery holds 6,144Wh, the F3800 7,680Wh kit with portable panels holds 7,680Wh.
• 240V loads. A well pump, a dryer or a central air handler needs 240V. The F3800 family delivers 6,000W with 240V output; the F3000 line is 3,600W and 120V-focused. Check your panel before you buy.
• Panel count for refilling. The F3800 + PS400 400W panel is a one-panel starter; the F3800 PLUS + 440W rigid panels ships with an 880W array and accepts 3,200W of solar, which refills 3,840Wh in a single decent day.
• Budget and footprint. The Bluetti Elite 200 V2 is 53.4 lb and 2,600W. It handles a fridge, router and phone chargers overnight and can take B80, B230 or B300 expansion batteries later.

Setup and usage tips

• Start with your outage load list, not the biggest unit. The Solar Kit Calculator takes your appliances and ZIP code and returns the battery, inverter and panel sizes that fit.
• Keep the station plugged into a wall outlet between outages so it is full when you need it. The F3800 PLUS models can start backup automatically before a storm.
• Put panels where you can reach them. Rigid panels on a rack or roof produce more per day, but folding panels stored indoors survive hail and can be moved out of shade.
• Run a test outage. Flip the main breaker, plug in the fridge and furnace blower, and watch how many watts the display shows. This tells you exactly how many hours you have.
• Do not run a whole-house load through an extension cord. For hardwired circuits, look at the F3800 PLUS models with a home power panel, sold in our electric generators collection.

Frequently asked questions

What is the best portable solar generator for home backup? For most single-family homes the F3800 with the PS400 panel is the balance point: 6,000W and 240V for pumps and HVAC, 3,840Wh in the box, and expansion up to 7,680Wh in the larger bundles. Smaller households do well with the Elite 200 V2.

Can it replace a gas generator entirely? For lights, refrigeration, communications and a furnace blower, yes. For running central air for a week in overcast weather, a battery unit needs more panels than most yards hold, so plan on rationing the big loads.

How long does solar take to refill it? Divide capacity by real panel output. A 400W panel on a clear day typically returns 1,500 to 2,000Wh; the 880W F3800 PLUS array roughly doubles that.

Every portable emergency backup solar power generator here ships free to the mainland US from our brand partner warehouses, generally within a few business days, with 30-day returns. Call us with your appliance list and we will size the backup with you.
