Currently have a 5 year old sunrun panel only system-

Any input on how complicated it would be to add this? Im not too worried about storage capacity (I'd probably get 2) but mainly want my system to work during outages.

LOL, yeah it does! My jaw hit the floor when I saw three 15KWH batteries and a 10KW inverter for that price. Indeed, too good to be true.

Use AC coupling with split phase inverter. Need turn off grid input when grid is down. Then use split phase inverter off grid mode to create 240v to make original solar inverter think grid is still on to turn on solar. Need to monitor solar production not overrun appliances and battery since no real grid to dump excess power.
