    I run my whole house on two anker f3800 with a double power hub. I run a 13000w predator generator 3-4 hours a day, a 6000w would be enough if that is all its used for. I plan to add solar in the spring. https://www.ankersolix.com/products/f3800

    >A dual Anker SOLIX F3800 with expansion batteries costs around $10,000 and provides about 15 kWh of power. 😮 Damn! Glad I went DIY. 48V 100ah batteries are as low as $700 each right now. I could make a bank that is 68.5kWh for the same investment. Maybe at some point, but with a good amount of panels or using a generator to top them off as needed like you mentioned, I think the 8-ish I have now will suffice.

    I watched countless YouTube videos and read countless reviews about this market over the last two weeks and Ecoflow comes out on top basically every time. The only thing I’m not getting through Ecoflow is the panels and that’s because you can get a lot more for your money if you don’t go for foldable ones. I wish I would have bought on the last Amazon Prime sale, but I’m going to get the Delta Pro Ultra on Black Friday. I’m just some dude though, so what do I know.

    I might just need one F3800 with two expansion batteries, which provides 12kwh power to run my essential appliances. I just checked their website and found out they're around $6K. That looks reasonable. Bluetti ac500 and ecoflow delta pro might not in my lists cuz they cannot support 6000W, while delta pro ultra is too expensive. I need one can go up to 6000W and support high-voltage appliances like AC, fridge and my LG dryer.
