Battery inverter connectivity layout

This is probably a silly question, but I'm to understand what a battery-only installation would physically look like. A lot of the diagrams online show the inverter sitting inline between the incoming power board and the main distribution board in the house (such as https://images.squarespace-cdn.com/content/v1/5354537ce4b0e65f5c20d562/1491982203583-0ZWU80YSVXWT6XO3H8DX/basics+layout+of+a+grid+connect+solar+power+system?format=750w ).

However, others show it alongside the incoming circuit (for example https://491156-1550122-raikfcquaxqncofqfm.stackpathdns.com/wp-content/uploads/2021/03/solar-panel-diagram1-1024x614.png) 

(I appreciate these pictures also show solar but it's difficult to find diagrams of battery-only installations)

I'm just trying to understand what the cabling would look like as I would like to install the batteries on the outside wall if possible, next to where the main supply and meters are

Thanks

Hi Mike, generally speaking if you are going for what we tend to call an AC system which is that its charged from house electricity rather than directly from the panels themselves,  something like the sofar me3000sp or lux 3600 as then it should probably be shown as a circuit on a leg of its own rather than in the middle of something like your solar.

Outside wall beside main supply is perfect, as the system will use current clamps (CT) to look at your live line into your meter and by viewing it, decide if it needs to supply energy to your house or not to stop you buying electricity. 

The CT clamp is what controls everything. 
If you are buying electricity it ramps up your inverter until is sees nothing coming in, that way you are running from the batteries.

Hope that makes sense

Ignore the stuff in the circle and ignore the pv inverter if you have no solar
