I purchased an Anker Solix F3800 in March of 2024 with the intention of using it as I develop my property in Idaho. It has proven to be an invaluable tool, and as I've used it in various scenarios, I've learned a lot about its quirks and undocumented "features".
I use the F3800 to power my tools and recharge batteries, to provide light where I'm working, run my well pump and more recently to provide power to my 40ft. Class A diesel pusher motorhome. It's been quite reliable, but it does have a few issues.
First, should you purchase one, be sure to hook it up to wifi and update the firmware. Prior to doing that, I was unable to use AC power (from my RV Generator) along with solar to recharge it. I'm currently running firmware 2.1.5, which does allow simultaneous AC and DC charging.
Second, the MPPT controllers built in for solar are optimized for Anker's proprietary solar solutions, which are relatively expensive. Pay close attention to how you configure your solar panel wiring to optimize charging. Assuming you can find the right combination of serial/parallel connections, you can charge the F3800 with up to 2400 watts of solar power, but it's not easy to get to that number.
Third, the built-in BMS limits charging current when the batteries are colder than 10c/50f. I've discovered that you won't be able to put more than about 710 watts DC or 685 watts AC into the F3800 if the battery temp reads below these figures. (Quick tip - put a heavy AC load on it to get those electrons flowing and warm up the batteries in the morning!)
IF the batteries are above 10c, it will charge quickly with solar or AC input. I manage to push about 1500 - 1600 watts into it at peak sunlight with my two strings of panels, and at that rate it only takes a few hours. If you're charging a warm unit with AC power, it will charge completely in under two hours, assuming you have not limited the AC power for charging via the app.
Overall I'm very pleased. the phone app (I use IOS) is good, but could be improved by adding input and output power over time. It has graphs, but since those numbers are constantly changing, there's no way to track usage.
Overall, I'm very pleased with my purchase. Anker support is responsive, although it took almost a week of emails back and forth to find out that my "charging problem" was because the batteries were cold and current was being limited by the BMS. For those of us who understand solar, batteries, BMS, etc. 50 degrees F is a pretty high threshold under which to limit current. Hopefully Anker will reduce that to a more reasonable level in a future firmware update. With such a high temp. hurdle the usefulness of this device will be less than desired as the cold weather approaches.
For those wondering, it *does* allow you to use a plug-in EV charger to charge your EV. I've tried it on my Rivian R1T, although the capacity of the Anker is a drop in the bucket for an EV with a 131kW battery!
Highly recommended due to typical Anker quality, flexibility of use and expansion capabilities. It offers a reasonable value proposition when purchased on sale or in bundles.

The Anker F3800 is well thought out and provides great backup power when needed. A single unit can handle up to 240v and 6000 watts. However the base unit is 3880kw of battery storage. Know what you are trying to run and if you don't plan on adding expansion batteries (or a second unit) then you may be disappointed in the run time during an extended outage. I have 2 units and 4 expansion batteries but that can get costly so understand what your use case is. You should also figure out if you need a plan if your outage goes on for days, how you are going to charge the F3800. You can use solar but for many that may not be an option. My choice is to use a EG4 chargeverter hooked up to my gas generator to recharge if I need to. If you at all interested in this product join the official Facebook Anker Solix F3800 group. There are literally thousand of posts describing solutions on how best to use your F3800 as a primary source of power for a home or RV or as backup power utilizing a standalone unit, one hooked up to the Anker Home Power Panel or using the dual power hub. And if you have a problem the group is there to help.

The Anker SOLIX F3800 has proven to be an impressive addition to my power setup. The setup process was straightforward and user-friendly, which was a pleasant surprise given the complexity of some power systems. The unit's ability to connect via Bluetooth or Wi-Fi made monitoring and controlling the system convenient, especially using the iOS interface, which was a breeze to install and navigate.Visually, the SOLIX F3800 looks fantastic once installed. The design is sleek and modern, blending well with the surrounding environment. The unit's build quality is outstanding, and it was also very well packed, ensuring it arrived in perfect condition. The inclusion of wheels and a telescoping handle, along with locking wheels, makes the 130-pound unit much easier to maneuver despite its weight.I’m currently using the SOLIX F3800 with an AC Transfer switch via the 220 VAC output. While this setup works well, I've encountered a limitation: the 220 VAC output is disabled when the unit is connected to AC input power with the 220 VAC output enabled. This prevents me from leaving the AC Transfer switches in the "Generator" position. However, this issue does not occur if connected to the DC charging inputs, typically used for solar panels. To work around this, I'm considering purchasing DC power supplies for the DC inputs, which would add approximately $500 to the project but should resolve the problem.One area where I feel the product could improve is the manual. While the instruction manual is available in the app and can be downloaded, I would have preferred a professionally produced hard copy. Overall, though, the Anker SOLIX F3800 is a robust, well-designed power solution that has met my needs with only minor caveats.
