I have two of these units now and an extra battery for one of them for more runtime. I also have the 500 watt solar panel setup which does get a full 500 watts in full Florida sun and charges them in a couple hours each normally. I use them as continuous power for criitcal things like the Starlink connection and charging the phones and if there is an extended outage I'll use one for the refrigerat Mark · walmart.com

The EcoFlow Delta Pro Ultra was easy to set up. Everything came in two boxes. One for the inverter and one for the battery(6 kw capacity). Looks like the picture and already has the 14-30 outlet to deliver 7200 w to your transfer switch. This is a plug and play unit. Easy to recharge with 120 outlet when your power returns. This unit worked perfectly with the free APP. Delivery was 2 business days Ned · homedepot.com
