I'm really surprised the light and heavy loads backup options are so much more expensive compared to the main breaker separation.For a basic install that only connects, does not go inline between the meter and the box its still over $4500. I did talk to the installer and he had frustrations with the options available for them to enter. Everything was dropdowns and they could not put in their numbers.
I watched most of the install and it was 2 people for most of the working day. My install was just under $2,400 and including moving 1 circuit (fridge) from my 2nd 200A panel to the one being backed up for an additional $110.
The installer provided the 200A (new) main breaker for the Gateway and the 3/0 Cu wire to go from the meter to gateway to panel. Likely less than 15 ft total in wire, but expensive wire. Since one of my existing main panels was now a sub, they needed to split ground and neutral for all of the existing circuits.
There should be less labor for either load backup option, since you don't even need to pull the meter. It should just be running an appropriate breaker for the gateway as a sub panel and splicing over whatever loads (5-10) you decide to backup. Even needing 10 new arcfault breakers and splicing over 10 circuits should be less labor and parts than the main breaker separation rate.
I would expect light load backups to be the same rate as main breaker separation and heavy loads backup maybe $500 more.
