Anker SOLIX F3800: the full buy-or-skip review

Is the Anker SOLIX F3800 worth buying? Short answer: buy it, if you want 240 V backup for less than the Plus. This review explains what this Anker model gets right, where it falls short, what it usually costs in the US and which home backup battery to buy instead if it is not the right fit for you.

What the Anker SOLIX F3800 does well

The headline: 3.84 kWh station with 240 V. Key specs: Capacity: 3,840 Wh; Output: 6,000 W (120/240 V); Expandable to: 26.9 kWh; Battery: LiFePO4. In our list it is the pick for: value 240 V. It usually sells for $2,499–$3,299.

Often discounted against the Plus.

The trade-offs

Good: 240 V, 6,000 W, expandable, wheels. Not so good: heavy, fewer extras than Plus. Read the skip-if line before you order: skip it if you need 6 kW output.

What to buy instead

Instead, consider the EcoFlow DELTA Pro 3 ($2,999–$3,999): 4 kWh expandable station with 240 V output. Better if you want backup for well pumps and big appliances.

Instead, consider the Anker SOLIX F3800 Plus ($2,999–$3,999): 3.84 kWh station with 6 kW output and 240 V. Better if you want strong home backup with expansion.

Instead, consider the Jackery Explorer 5000 Plus ($3,999–$4,999): 5 kWh station with 7.2 kW output. Better if you want a large, simple backup.

Before you buy

Output: 3,000 W or more (and 240 V on some models) is needed for well pumps, sump pumps and central air. Expansion: extra battery packs let you grow from 3–4 kWh to 10+ kWh as needs change. Connection: a transfer switch or smart panel, installed by an electrician, lets the battery power home circuits safely.

US buyer tip

Battery storage may qualify for the federal residential clean energy tax credit when installed as part of a home system; check current rules with a tax professional before you buy.

Prices on Amazon.com move in a pattern. The deepest cuts land on Prime Day in July, Prime Big Deal Days in October and the Black Friday to Cyber Monday week, with smaller drops around Presidents Day, Memorial Day, the Fourth of July and back-to-school. Judge a deal against the usual price we show, never against the crossed-out list price.

Order from Amazon itself or the brand's official storefront so the US manufacturer warranty applies, keep your order confirmation and register the product with the brand. Most items can be returned within 30 days, and holiday purchases often get an extended return window into January.
