Very funny.
It seems that running dual battery banks is more popular on boats because one battery will start the engine and the other to run the rest of the boat.
Dual Battery Bank Controllers do exist
They charge 2 battery banks without connecting them.
There would have to be some sort of switch which would change the connection to the inverter according to the master battery voltage,
once the cut off point on the main battery is reached it would change over to the backup battery when necessary.
There must be a lot of people out there who would like to have a system with 2 battery banks.
For example if the main battery starts to show signs of age and you want to get some new ones but the old ones still have some life.
Someone gives you some batteries etc.
Someone ought to market this.
I still have my original batteries: 2 large lorry batteries connected to 20 watt panel with a cheap charge controller.
They supply lighting to an outside area for having beers in the summer.
I don't like throwing stuff away that is still useful.
