Best praise vs top criticism for EcoFlow DELTA Pro
βYa 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 videoβ
βI'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.β

Best praise vs top criticism for EcoFlow DELTA Max
βcheck out ecoflow, I used one of the more expensive models to run the refrigerator and a portable ac unit after the hurricane. You can charge them with solar panels.β
βBack to back snow storms both being blizzards is pretty crazy. I lost power for a little over an hour this morning and of course my Ecoflow that I normally dedicate to the refrigerator was off getting its warranty tested.β
