Best praise vs top criticism for Anker SOLIX F3800
Best Praise
+4 ptsāI 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/f3800ā

+1 ptsā>A dual Anker SOLIX F3800 with expansion batteries costs around $10,000 and provides about 15 kWh of power. š® 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.ā

+6 ptsāWife and I each have one of [THESE](https://www.anker.com/products/a1695-anker-power-bank-25000mah-165w?variant=44320657997974&ref=power-banks) from Anker (best battery backup I've ever used) and then [THIS](https://www.ecoflow.com/us/river-pro-portable-power-station) big boy from EcoFlow with a couple fold out solar panels. Done us great through multiple trips and power outages. Pretty much my perfect setup, not sure what I could improve if I wanted to beyond more solar for faster charging, maybe another big battery unit (they can daisy chain) but I haven't ran the one I've got dead yet so it's clearly not pressing. We also have [THIS](https://www.bougerv.com/products/crpro30-vip-30-quart-portable-fridge) electric cooler that can plug in or use a 9h battery for camping/travelling/power outages. VERY happy with it's first road trip from Seattle to Vegas and back, when we got home with covid we just plugged it in and our leftovers were still 31f a week later when we felt good enough to unpack.ā
