My Solix F3800 has been nothing other than a disappointment. Poor battery performance, especially when using AC, as it seems the inverter saps huge amounts of power just being on. The app is hopeless, and constantly wants you to reconnect with the unit. Switches work when they feel like it, the list goes on. I wish I'd stuck with Jackery, whose explorer 1000 I've used for many years, trouble free.
Anker Solix F3800, probably the worst buying decision I've made this decade.

Great customer service, and awesome product.

The F3800 arrived in excellent condition, already charged to an impressive 80%. Charging it to full capacity was effortless, and the firmware update went smoothly. Although I haven't had the opportunity to use the solar panels yet, it's reassuring to know the system is ready for future needs.

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.
