Our community has rated this post as helpful. If you agree, why not thank

For anyone interested in this, I have a shp2 and 12kwh in my townhome. Only critical circuits, including air handler(furance) but not the outdoor unit.
EcoFlow only wants the batteries charged to 80% and cutoff at 10%, unless "storm guard" is activated, then it charges to 100.
It's not enough to run your entire house for a day. If i had two of these, it would.

48v 200a battery = 9.6 KWH, So Unless the inverter is worth 4K I don't see this as a great deal//

You can do 0-100, just adjust the settings. Lfp is meant to deep cycle, just dont let it stay at 0

Great deal on these. I have two stacks with 3 batteries each. Runs the house about two days without the AC, dryer, stove, and dishwasher.

Still need to be grid tied. No options to be self-generation mode.

They are getting cheaper though. Hopefully they will release a full off the grid version of this.

I've been searching the marketplace in the Los Angeles/Inland Empire area for several weeks now, and this deal appears to be the best one I've found. Essentially, you're paying $1,666 (before tax) for each unit, inverter and two batteries. I'm not sure if there's been a better deal available.

Should you buy this, Costco has a better return policy.

Also new units have 5 year warranty, refurbs have 2.
