All that and only 120v. Ouch. I do have a Mega 2 and like it, but for my 240v needs, I had to get the Anker F3800

Not disagreeing, but what 240V are you guys using? I recently got delta 2 max, but can't quite imagine what you're running, a dryer?

Don't know about the quality of this company but this looks far and away to be the best deal on a power station that I've seen over the last couple days

Would it be possible to wire this with a transfer switch if you dont need 240v?

split phases. IF you wire this into your house you've want both sides.

just ordered the ecoflow delta pro with 2x220 w panels.

now seeing this. specs here seem better, but not seeing much about this brand in researching in. I know ecoflpq isn't perfect, but it's the devil we know.

anyone have a POV on this brand? and how it compares to ecoflow in terms of quality, app and service?

I've reached out to the manufacturer to confirm - it is possible to connect this to DC (solar) and AC (mains) at the same time and draw power from both, as well as passthrough. There seems to be conflicting information available, but the Oupes site claims a max solar input of 2,100 watts over its Anderson port. This is a significant improvement over the Ecoflow Delta Pro at 1,600 watts max solar input. However, the Oupes MPPT is hard limited to 18-140V, 15A. It may be difficult to match an rigid panel config to maximize the MPPT and stay within spec. With my 550w panels, it seems the best I can do is 3x550 for ~1,650 watts wired in series, which should recharge the Mega 5 in about 4-5 hours of ideal harvesting conditions.

My water well pump. That is my biggest need when my grid supply isn't working. Most everything else is just conveniences.
I'll be sticking with a liquid fuel-powered generator until these battery systems become more reasonable for my needs.
