Home backup

Anker SOLIX F3800 Plus: connecting it to your house

Stock: the F3800 Plus on its own was sold out on Anker's US site on November 14, 2026 (and on Nov 6). Anker was selling it in stock as a bundle with the Home Power Panel kit.

Anything that connects to your breaker panel is a job for a licensed electrician, with a permit and inspection. That covers inlet boxes, interlock kits, transfer switches and the makers' smart panels.

Never power house wiring by plugging a battery or generator into a wall, dryer or range outlet with a double-ended ("suicide") cord. That is called backfeeding: it is illegal, it can electrocute utility lineworkers and neighbors on the same transformer, and it bypasses your home's circuit protection (CPSC, OSHA).

The three options for an F3800 Plus

Anker prices are the regular prices on its US store on November 14, 2026, before its timed discount codes. Installed ranges are HomeGuide's (figures dated April 5, 2023); your electrician's quote is the real number.

Which one to pick

Lowest cost, every circuit reachable: inlet box and interlock. You are the load manager: turn off what the F3800 Plus cannot carry before you turn it on.
Fixed circuits, hard to overload:the 30 A version of Anker's 10-circuit switch. Do not buy the 50 A version for one unit; Anker labels it for an F3800 or two F3800 Plus units.
Want it automatic, or plan to add solar or a second unit: the Home Power Panel. It is the only option here that switches over by itself and the only one that ties in rooftop solar. Anker notes that grid-tied solar shuts off in an outage, so it cannot recharge the battery until the grid is back.

Before the electrician wires anything, settle the neutral: Anker warns that a missing neutral or ground at the inlet box or switch can damage appliances on the circuit. Size the outage first with the power outage backup calculator: one F3800 Plus holds 3.84 kWh and expands to 26.88 kWhwith Anker's expansion batteries.

Frequently asked questions

Can I connect an Anker F3800 Plus to a transfer switch without the Home Power Panel?

Yes. Anker says the F3800 works with a home transfer switch or inlet box: connect the right cable from its 240 V outlet, and make sure the neutral and ground wires of the inlet box or switch are properly connected, because a missing neutral or ground can damage appliances. The F3800 Plus has one 240 V outlet, a 30 A NEMA L14-30R. A licensed electrician installs the switch or inlet, with a permit.

Which Anker transfer switch fits one F3800 Plus?

The 30 A version of Anker's 10-circuit manual transfer switch (a Reliance Pro/Tran 2, regular price $789.99 on November 14, 2026). Anker's 50 A version is for an F3800 or two linked F3800 Plus units; its page says it is not suitable for a single F3800 Plus.

Does the F3800 Plus switch over automatically in an outage?

Only with Anker's Home Power Panel. Anker says that when the grid goes down the panel switches by itself and powers the circuits on its subpanel, up to 25 A with one unit or 50 A with two. With an inlet box and interlock, or a manual transfer switch, you flip it over yourself.

How many circuits can one F3800 Plus run?

It depends on what is on them, not how many there are. One unit gives 6,000 W at 120/240 V (25 A, per Anker). A manual transfer switch caps you at the circuits wired to it (10 on Anker's switch); an interlock lets you reach any breaker, so you must keep the total under the unit's output yourself.

Is the Anker F3800 Plus in stock?

Not on its own when we checked: it was sold out on Anker's US site on Nov 6 and again on November 14, 2026. Anker had it in stock as the F3800 Plus + Smart Home Power Kit bundle on November 14, 2026.
