Our take on the 2× Anker SOLIX F3800 Plus + Power Backup Kit

This bundle pairs two Anker SOLIX F3800 Plus portable power stations with a Power Backup Kit, giving a home a large dual-voltage battery bank with transfer-switch style backup. Each unit delivers 6,000W AC output across 120V and 240V, takes up to 3,200W of solar through dual MPPT controllers, and can be charged from a 240V gas generator. Capacity starts at 3.84kWh per station and expands toward 26.9kWh with add-on batteries, using EV-grade LFP cells rated for 10+ years. It suits homeowners who want whole-home or critical-circuit backup without a permanent generator, and it competes with large home batteries on output and expandability rather than on portability.

Questions and answers

How much can this kit power at once?
Each F3800 Plus delivers 6,000W AC output at 120V and 240V, and the pair can reach 12,000W combined. That covers most home appliances, including dryers, well pumps and EV charging.
Can I charge it from a gas generator?
Yes. It accepts 240V gas generator charging with a 6,000W bypass, so a generator can run loads and recharge the batteries during long outages.
How much solar can it take?
Up to 3,200W of solar input through dual 11-165V MPPT controllers, which lets you recharge quickly with a sizable array.
How far can capacity be expanded?
It starts at 3.84kWh per station and expands up to 26.9kWh with additional batteries, which are sold separately.
What is included in the Power Backup Kit?
The kit adds the hardware needed to connect the two stations for home backup. Check the box contents for the exact transfer and cabling parts.
Can it charge an EV or RV?
Yes. The NEMA TT-30P and L14-30 ports let it charge EVs and RVs directly, though large EV charges will use capacity quickly.
