The correct low-budget way to connect one of these is using an interlock kit: https://www.se.com/us/en/product/HOMCGK2C/load-center-accessory-homeline-interloc

  Yes! Not only is a mechanical interlock a code-compliant method to properly protect downstream line workers but it is also a simple and comprehensible component that costs very little and never breaks. We have a whole-house generator connected to our main panel and I made a very deliberate decision not to add the complexity and fragility of an automatic transfer switch. The little metal tab will always work and nobody will ever be confused.
