We purchased an EcoFlow Delta Pro Ultra and Home 2 panel and had an electrician install it.
I love the app interface and 12 slot transfer box that now contains 90%.of our circuits.
The local electrician wasn't familiar with the new Home 2 panel, but it was so straightforward he was quite glad as he was familiar with the Home panel of old, which is far more difficult to install.
He called his colleague electricians over to watch the last hour of install as kind of a tutorial, so I am happy with the stupendous ubiquitous Delta Pro Ultra and panel with 3 multi use inputs!
