These solar transfer switches are typically mounted between the utility meter and the solar inverter. The switch will then monitor both sources, and connect to the alternate source whenever necessary –
Combiner boxes, isolator switches, and disconnects are the traffic controllers of your solar array. They manage the flow of power, provide vital protection, and allow for safe
Safely turn on, shut down, or restart your solar inverter with this step-by-step guide. Ensure proper operation and troubleshoot issues.
An AC disconnect is generally mounted to the wall between the utility''s meter and the solar inverter, and can either be a separate switch or a breaker in an electric service panel.

Combiner boxes, isolator switches, and disconnects are the traffic controllers of your solar array. They manage the flow of power, provide vital protection, and allow for safe maintenance.
A PV switch disconnector is an essential safety component of any solar setup. It can stop AC or DC power before it reaches the inverter or the grid meter.
Get the whole system up before you plug in shore power. Then on disconnect you would unplug shore power first, not last. Your posted order of operations looks good. I would consider
