Received everything a week later, only the electrical panel took 2 weeks.
Received the wrong cable for the home panel. I communicated with customer service by email, they shared multiple scenarios and asked what I preferred.

Refund was done within 24 hours for the cable.

Can't wait to set everything up.

UPDATE:

I was starting to prepare my installation. I open the box from my transfer switch. I wanted to seperate and attach each wire that goes together. Red A wire with Black A wire, etc...

3/4 of my wires are not identified. I will now need to open the complete panel and follow each wire to be able to identiy what transfer breaker it goes to. Each wire passes under the breaker to go to the transfer breaker.
Not very happy with this find. I know and understand that it's not Anker's fault, since the panel comes from Reliance controls.
But this transfer switch is sold as a kit with the Anker F3800 Plus, so I expect it to be up to par. And it's not, I just added 1 hour to my preparation, because my wires are not identiied on my transfer switch.

works like a charm... just wondering why the backup kit isn't automatic. that way we didnt get any downtime while were not at home. but other than that, its perfect.
