I have purchased the HA Green already LOL. I was determined. Now less so.
In that case, sit on it for a bit. Have a gentle play as and when the mood takes you and simply get a bit more familiar with it when you feel up to it. If at any stage you want to get a bit more adventurous and need a spot of help you can always drop me a line.

@transparent I hope that Mars thinks such a topic would have legs, for even if I cannot contribute anything useful myself, I would like to read what others think! Regards, Toodles.

I've got a few things integrated such as my TV, Melcloud, Solar Forecast and others. But they were easy as pressing a few buttons. I will eventually wish to understand how to instal the HACS so that I can have a go at getting more control of my battery storage etc. But I can wait and as you say, play until I gain more understanding. Never know the penny might just drop in one day re the HACS.
Thanks for your time and patience.

There's some background research required before the proposal can be made appealing to Social Housing providers.
For a start, have a think about the need to have 3-phase input to charge batteries from the grid, but still have single-phase supplies to each house.
A. Is there an inverter which could operate like that?
B. Or would it need to be one type of 3ph inverter for charging, and another single-phase type to take the battery voltage and supply it to houses at 240v AC?

Or you could possibly have 3 single phase inverters, connected from each phase of the grid supply to a common storage battery. The inverters may be able to reduce phase imbalance, by drawing power from a lightly loaded phase and feeding it to a more heavily loaded phase via the battery, with the DNO supply seeing approximately equal loading on each phase.
This arrangement could also help smooth out the peaks and troughs of demand, by charging the batteries during periods of low demand and then using the stored energy to help supply periods of peak demand, while also helping to reduce phase imbalance.
One possible benefit of this arrangement would be that not all the demand is going through the inverters, since power would still be coming from the distribution network. A further benefit is that one or more inverters failing should not cut off supply to the consumers.
@transparent I will leave you to do the graphic at which you are much more accomplished.
