Best praise vs top criticism for Anker SOLIX F3800
Best Praise
+4 pts“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”

+1 pts“>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.”

+3 pts“Was just going to post this. Plug it in the wall then plug in the computer or TV or whatever. It will always be ready. Have a number of them. The Ecoflow River 3 line is quite impressive for charging those devices.”

+2 pts“I have the EcoFlow River 3. It is great for running an LED light or two during a power outage. However, charging a couple phones and tablets knocked the battery down significantly. River was dead after second charging of all devices. I feel you will be greatly disappointed in its performance running those appliances on it.”
