+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”
r/preppers
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.”

+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.”
