Question about EcoFlow Delta 2
What is your own consumption with the Ecoflow Delta 2? The following self-reported practical values make me doubt the sense of this emergency supply solution. With only 13 watts of LED lighting at the 230V AC output, a total of 87 watts are consumed. That means 74 watts for the inverter operation alone! After 12 hours the battery would be empty! 2. unit in standby, 230 V output ON so that e.g. the room lighting can be switched on at any time without further manipulation. This 230 V standby mode consumes 47 Wh per hour, so that the battery is empty in approx. 22 hours, despite no load. 3. 3. all outputs OFF. Unit in standby so that the outputs can be switched on remotely via the app at any time. Test consumption per hour, despite zero load, 15 Wh. This means that the battery would be empty in approx. 68 hours despite zero load. In cloudy weather, the 305 W solar panel installed on the inside of the balcony (rented flat) cannot compensate for these energy losses either.
Hello René,
Realistically, the thing is not an emergency power group, it would be dimensioned completely differently. But I can probably keep the fridge and freezer undamaged in the event of a power cut until the electrician arrives. I can imagine many other scenarios where the device would be very useful, but first I have to calculate the power requirements.
Sure, rechargeable batteries have self-discharge. Sure, any standby operation consumes power, and so does a running inverter. And if I want to protect the device, I narrow the charge limits somewhat (no deep discharge, full charge only when needed), which reduces the capacity again.
The question for me is not primarily how much power I am promised, but rather how can I use the thing sensibly, simply and above all flexibly? From temporary power failures to garden parties, working outdoors, emergency radio operation, camping, using it as a buffer, regulating small solar systems, and so on. The strength is flexibility. If capacity is the most important thing, then I tend to research larger storage systems.
Helicopters come to mind: energetically horrible as a means of movement, but sometimes the only salvation. I could get upset at how much energy it wastes hovering still at one point until I might need it urgently one day....

The same problem was found. For this reason, the Delta 2 can only be used as a solar power buffer to a limited extent.
