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.”

+7 pts“Ya I watched this video of him running the delta pro with solar and he showed how long it would run his fridge on solar only solar good video”

ViewTop Criticism
+1 pts“I've been looking at doing exactly what you describe: 2 Anker F3800+'s with the dual hub connector can provide up to 12KW same as your generator. 2 Ecoflow Delta Pro 3's can be similarly combined for 8KW. Costco had a sale for the 2 units for $4200 that just ended. Ecoflow looks cheaper, but their support from China is worse... firmware updates can turn the system into a brick. Ecoflow also advertises you describe with their smart generator started/stopped by the battery... they claim something like a 40% increase in efficiency by letting the generator run at peak performance. Your idea also lets you use a much smaller generator as you only need to supply the average load vs. the peak loads. It's also a lot quieter when only running the generator to top off the batts... probably won't run at all over night.”
