Anker SOLIX F3800 Plus with BP3800 Expansion Batteries: Buy the Runtime You Actually Need
Every BP3800 adds 3,840 Wh to the F3800 Plus. Choose one for 7,680 Wh total, or step up to five for 23,040 Wh, which is genuinely multi-day whole-house territory. What does not change is output: 6,000 W continuous with 120 V and 240 V from the built-in L14-30 port, regardless of how many batteries are attached. Batteries buy hours, not headroom.
One thing worth knowing before you choose. Anker rates generator bypass at 3,300 W for a bare F3800 Plus and 6,000 W with one or more expansion batteries installed, so even a single battery meaningfully improves how fast a 240 V generator can refill the system. Beyond that first battery, each additional one is purely storage.

Why the F3800 Plus
From 7,680 Wh to 23,040 Wh
One to five BP3800 batteries on this listing, and the platform accepts six for 26.9 kWh on a single unit. Every battery is the same 3,840 Wh module.
The First Battery Doubles Generator Bypass
3,300 W bare against 6,000 W with one or more batteries. If you own a 240 V generator, that first battery pays for itself in recharge speed.
Runtime, Not More Power
Output stays at 6,000 W continuous no matter how many batteries you stack, because the inverter lives in the power station. Plan around hours rather than watts.
6,000 W With Both Voltages From One Box
A built-in NEMA L14-30 delivers 120 V and 240 V from a single unit, so a well pump or a dryer works without pairing two power stations. Two units in parallel reach 12,000 W.
3,200 W of Solar on a 165 V Window
Dual MPPTs accepting 11 to 165 V at 17 A each. The wide voltage range is what lets you series rigid panels instead of running many parallel strings.
3.84 kWh to 53.8 kWh
Six BP3800 expansion batteries take a single unit to 26.9 kWh. Two units with twelve batteries reach 53.8 kWh, which is weeks rather than days.
What's Included
In the Box
Anker SOLIX F3800 Plus Portable Power Station, 3,840 Wh
Anker SOLIX BP3800 Expansion Batteries, quantity per the option you select, 3,840 Wh each
AC Charging Cable
Battery connection cabling
Quick Start Guide and Safety Documentation
Battery quantity follows the option selected above. A single F3800 Plus accepts up to six BP3800 batteries for 26.9 kWh total. Each BP3800 weighs 72.8 lb, so a five-battery stack is well over 500 lb in total and needs a floor and a route planned for it. Solar panels, transfer switches and Home Power Panels are sold separately.

Anker SOLIX F3800 Plus with BP3800 Expansion Batteries: Buy the Runtime You Actually Need: Frequently Asked Questions
How many batteries do I actually need?
Work backwards from your daily consumption during an outage. A fridge, lighting, networking and a furnace blower typically land between 4 and 8 kWh a day. At 7,680 Wh the base plus one battery covers roughly a day; five batteries and 23,040 Wh gets you to three or four. Add solar and those numbers extend considerably. Call us at (303) 876-7654 with your must-run list and we will do the arithmetic with you.
Does adding batteries let me run bigger appliances?
No, and this is the most common misunderstanding. Output stays at 6,000 W continuous with either one battery or five, because the inverter is in the power station rather than the batteries. If you need more than 6,000 W, the answer is a second F3800 Plus on a Double Power Hub for 12,000 W, not more batteries.
How is the F3800 Plus different from the original F3800?
Three things. Solar input goes from 2,400 W to 3,200 W, on a much wider 11 to 165 V dual MPPT window instead of 11 to 60 V, which is what allows series-wired rigid arrays. It adds true generator bypass, which the F3800 does not have, at up to 6,000 W on 240 V. And the special AC sockets differ: the Plus has a TT-30 rated 3,000 W plus an L14-30 rated 6,000 W, where the F3800 has a NEMA 14-50 and an L14-30. Capacity is the same 3,840 Wh on both.
How far can I expand it?
Up to six BP3800 expansion batteries on a single F3800 Plus for 26.9 kWh. Pair two units with twelve batteries and you reach 53.8 kWh. Anker confirms that an F3800 and an F3800 Plus can be used together on a Double Power Hub or a Home Power Panel, so an existing F3800 owner can add a Plus rather than starting over.
Can I run my whole house on it?
Depends on the house and how it is connected. 6,000 W with 120 V and 240 V from a single unit covers most essential circuits including a well pump or a furnace. Two units in parallel give 12,000 W, which reaches most homes outside of central air conditioning on a hot day. The connection method matters as much as the wattage, which is where the Home Power Panel, a transfer switch or an inlet box comes in.
What does the generator bypass actually do?
It lets a 240 V generator pass power straight through to your loads while also charging the battery, at up to 6,000 W. Anker rates a full recharge from a generator at about 1.5 hours and claims up to 50 percent better fuel efficiency than running a generator continuously. Note that the Anker SOLIX Generator Adapter is required and bypass supports a single F3800 Plus unit only.
Which output ports work in which situation?
This catches people out, so it is worth reading Anker's port conditions before you buy. With no AC input connected, all ports work. Plugged into a 120 V wall outlet, only the TT-30R and the three leftmost UPS-backed NEMA 5-20R ports are usable, with a 1,440 W bypass limit, and the L14-30R is not available. With a 240 V generator connected, the TT-30R gives 3,000 W and the L14-30R gives 6,000 W, but the NEMA 5-20R ports are not available. Call us at (303) 876-7654 if that decides your setup and we will walk through your specific case.
Can I charge my EV with it?
Yes. Double-press the AC outlet button to enable EV mode and set the vehicle charging rate below 25 A. No adapter is needed; you plug the EV's own cable in. It is a range top-up rather than a full charge, since 3,840 Wh is a small fraction of a car battery.
Can rooftop solar recharge it during an outage through the Home Power Panel?
No, and this surprises people. During an outage you connect panels directly to the F3800 Plus solar inputs at 11 to 165 V. Exceeding 165 V will damage those ports, so calculate string voltage at your coldest expected temperature before connecting.
What is Storm Guard?
The system watches for severe weather alerts and charges automatically ahead of the storm, so the pack is full rather than half full when the outage arrives. Note that Storm Guard requires the Anker SOLIX Home Power Panel.
