Ecoflow has a good deal right now on this bundle.

Delta Pro 3 alone is $3199 after coupon code EF500OFF

Delta Pro 3 + 400 watt solar panel is also $3199 after 7% off (automatic in cart) and coupon code EF7PCTOFF

You are basically getting the 400 watt solar panel for free. This is a very good panel and easily worth $600 for used/refurbished or more for new

Can the 110v charging input be reduced so it only draws like 300 watts? I want to use this for power outtages and my base load is around 250 watts with peaks for well pump turning on. I think I could add a 400 watt inverter to my electric car and have access to my 72kw battery to slowly keep the ecoflow topped off.

I think this new Delta Pro 3 only goes down to a minimum of 400W AC input. That said, If you want charging from a vehicle, don't mess with AC inverters. Car AC inverters aren't typically pure sine wave, and Ecoflow units (along with virtually all other battery/inverter units like this) simply won't work off of simulated.

Consider something like a 12-24V DC converter for the car, because you can plumb that DC into the solar input of a Delta unit. I've tested mine with ~420W input off of a $140 Victron 12-24V 20A DC converter.

How do you limit the 12-24v 20 dc converter? 20amps is the max before it cuts out, but what actually limits it to below that? The app? Will it let you limit the solar inputs?

I ended up ordering the Delta Pro Ultra from the home depot price mistake for $2899 but I still need to get the charging figured out for storms.. I really want to tap into my EV battery.

You don't, that's kind of the trade off - the victron's a simple device.. 'take 12V in, provide 20-30V output up to 20A' - so it can pull up to around 50A if you let it, BUT.. the Ecoflow Delta 2 will limit itself to around 500W and in my testing will settle in around 420W @ the max 30V output, because the D2 has a solar input limit of 15A.

That translates to this converter using a max of about 33A from a running alternator or other dc power supply, to charge a Delta 2.
