Diagram Split AC bus with an inverter

[Newtugnut]

Please see link below for diagram of a split AC bus with an inverter.

Not only the hot wire connections are shown.

If you proceed, make sure it's done by a qualified electrician and done to ABYC standards eg: not shown, the neutral bus must also be split etc.

I know there are different kinds of inverters, and I am not an electronics expert. But, normally, an inverter on a boat converts DC to AC. Your drawing converts AC to AC. If it is AC to AC, wouldn't be called a transformer? Please explain.

He is showing an Inverter/Charger. The battery connection is not shown. An Inverter/Charger will pass through source AC when available and automatically switch to inverter power when the source is not available, like a UPS.
The Charger function is also active when the AC input source is available.

Howard is correct. Though strictly speaking I have shown an inverter not an inverter charger. Notice on the second Ac bus there is a connection for a charger shown.

If the inverter box was truly an inverter/charger you would eliminate the ac charger connection.

I could have shown dc connections to the battery from the inverter but thought the diagram would start looking messy.

The inverter as explained in another post is a pass through , due to the requirements if ABYC rules, treatment of neutral buses and ground buses etc.

Therein lies one of the problems, if the inverter fails all the Ac loads are lost in the boat. Hence, the single emergency ac outlet where all the heavy loads are connected.
