I already have solar panels and 5kw battery installed and I am looking to increase battery storage....spoke with Octopus who installed my solar/battery and they are saying £3500-£6000 for another 5kw battery installed. Thats a little steep so I have been looking at adding the Indevolt to the house which my electrician is going to add through a spur.

Will this get fed from solar this way or does it need to be connected directly to my panels?

I am looking for more storage to fill at night on cheap rate and the solar is not a real concern going forward.
