So both units are working as should, thanks

Well Designed - Works as Advertised

Bought this to allow battery backups that capability to run entire house including 240V systems such as main AC and a mini-split AC that is very efficient. Combined with duel fuel smart generator. In the event of extended outages, with the backup propane supply I should be able to operate for a couple weeks by running the refrigerators, cooling just the room with the mini-split, and recharging via solar and smart generator. App is great, and communications between the Delta Pros and smart generator works as described for auto-start and shutdown. Others have commented how the cables for the Double Voltage Hub and connections into the side of the Delta Pro could be improved upon, either with 90 degree connections or some other modification. Thus far that would be my only comment, otherwise great products and combination to allow whole-house backup.

EcoFlow home generator

After looking at a total home Generac Generator. The total cost and hookup was surprising. I then started to do research on other options. I saw good reviews on the EcoFlow and decided to go with two Deltaflow pros and the 400W Solar Panel. I will pair this with a medium gas generator for backup. This way I can charge up the EcoFlow if the clouds take over and run my house with the gas for backup of the Ecoflow. I like the idea of being able to move the portable Ecoflows with me during a Hurricane.

The Best Solar equipment Company in America.

I am very happy that I bought all my portable Solar Home backup Kit this month.
