Greetings Benn, There may be another option which would avoid extra controls/devices. The point of interconnection of the inverter output circuits could be a supply side connection; the inverter outputs could be combined and interconnected between the service point/utility meter and the utility supply connection to the automatic transfer switch. This may be an installation option to consider if allowed in the jurisdiction where your project is located and if practical given the existing electrical work and nature of the site/building.

The generator is located in a shed about 300' or more away and the feeders to the house are underground. Inverters are located in the house basement mechanial room along with the house electrical panelboard. We are looking for relay options to shut down the inverters when there is a power interruption, before the generator kicks in. This could be a manual reset. What are some options you have seen/used for something like this?
