โ€œA shame that the original post has gone, but I'll share my experiences anyway. I used to own an Ecoflow Delta 2 for my log cabin which I loved - it worked really well with about 1.8kW power delivery (could boil a travel kettle using it), but I found that it wasn't quite enough capacity to last a full weekend. We had a 50W coolbox attached to it, and it would be flat after a day. One thing you've got to realize is that the capacity that the manufacturer says you're getting is not what you actually get - this is because the inverter, display and fans all take energy, and in fact the useable amount of capacity on the Delta 2 was only about 800Wh. Talking of fans - the fans on the Delta 2 were REALLY loud, and that was one reason I decided to sell it. About 6 months ago I upgraded to an Anker power station (it's the Solix F2000 for anyone who's interested). It's got the all important Li-Po battery tech and a much more chunky 2048Why of capacity - (of which about 1700Wh is useable). I've coupled this with some solar powers and can now last almost indefinitely on free solar if I'm reasonably careful with what I use through the day. Overall I'd definitely recommend these things but they're not cheap - make sure you get a decent warranty - most of the big players are offering 5 years now as standard. I've not had any technical problems with either manufacturer though to be fair - hopefully it'll last me a long time!โ€

โ€œI 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/f3800โ€

โ€œ>A dual Anker SOLIX F3800 with expansion batteries costs around $10,000 and provides about 15 kWh of power. ๐Ÿ˜ฎ 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.โ€
