The inverter connects directly to the panel and has short DC leads.

Look at the "Component proximity" bit here:

There's probably other setups, but I bet this is how most of the small, cheap ones work.

I’ve not installed these balcony kits, but I’d be surprised if they used microinverters..

Either way, there is no issue using the panels in the kit you linked to in the way described; they are separate panels with standard MC4 connectors. Just unplug the inverter and plug in the grid forming one.

If you look in the menu, I've linked the setup that doesn't include any mounting hardware for the panels, but it's exactly the stuff that's used in the balcony kits.

We've move some distance away from toggling your transfer switch over to the battery charger. Just rewire all the panels, or put in relays at all the DC connections, or...

Huh, for some reason I assumed the balcony kits would be… “dumber”.

Either way, I’ve installed many panels with exactly these little boxes clipped to the back of them, and there is nice clean DC power to pull directly off the panel if you like by just disconnecting the inverter
