The build

Paul asks, will you have an IHD (in home display) to monitor generation export etc. remotely?

It's all on an app rather than a display, that way I can be a solar nerd from anywhere in the world rather than only when I'm in the house ?

Paul says (being a solar nerd) we're with Scottish Power and he finds a lot more useful info on the IHD than the app. He had a two year long battle with SP regarding a usable IHD  involving the ombudsman and finally quoting government requirements to SP before they gave him a working IHD. He won in the end  but it took ages. It was well worth the battle. There's been no solar today so he's grumpy.
