The whole discussion sounds more like a lesson in the dark arts at Hogwarts than a gathering of double glazing sales people. Still it has definitely raised the tone somewhat as even @pocster has been somewhat restrained (perhaps evolving into some sort of scientist) - and now he is brining a third battery to the party (in the EV) - this should be fun. PS I still think this will only work if the two sub-systems (PW and SE) can talk to one another and decide what to do when the overall system (the house incl charge point) is put under load and/or when PV / cheap leccy is available. I worry that the nulling idea, simple as it sounds - and the best ideas are the simplest, will come down to the resolution of their respective ADCs and associated response times - I can't put my finger on it but something about +ve feedback is ringing alarm bells in my head but it might just be the beer.

I am still unclear what you are saying here adding the SE without installing some sort of interventions is not going to work?

Lets suppose I build my own silencer how about I add in one of these: url = https://www.carbuilder.com/uk/condensing-radiator-380-x-360-x-50 and give myself the chance of providing heating and / or cooling?

Bullet proof vest might be more useful, but you are correct and I, like you, never go far without a pocket full on 1N4001s.

Can I suggest a meet at 12 noon tomorrow at the OK corale to sort this out. @pocster will bring the ammunition I am not sure that the obvious problem here is not more simply seen from the big picture. Whatever the equations you need to be able to act on them / what they tell you, and it isn't obvious, to me, how such interventions might be achieved with these two devices, their associated systems and controls.

Sorry it was above I must have missed it - only England beating Germany at football on the telly so not sure why I missed it.

That works.

Have you shared that somewhere I must have missed it.

Thanks Joe, that's very helpful, I was wondering how I was gong to make the dampers work for each of the outlets (inlets depending).

I found a pic of @joe90's system here:

I am just working up the design for my distribution and silencing system - do you have any more details of yours you can share - I think there was a post on e-build about it but that is long gone now.

Firstly can I admire and respect your wish to give this setup a try. It feels relatively obvious that unless they were designed to, or can by use of their settings be made to, work symbiotically that they will work parasitically - everything tends to chaos. Both the PW & SE assumes that they are "the only battery in the village" and behaves accordingly. Which does what to which probably comes down to the sensitivity of the respective front end - IE what they think they see happening on the wires and a fractional difference in interpretation will be enough to upset the applecart. As I see it you will need some pretty tricky control electronics, perhaps a sort of rules based MQTT broker like device (function of not form of) to get these two talking to one another and their respective PV arrays nicely - have a word with @Radian cos he seems to be the master of this sort of stuff!

Not sure it sounds like that!

+1 to that.

It is a risk, we haven't yet, probably won't but it does get tetchy - just yesterday we verged on shouting at each other about the shape of a roof light reveal. I wholly missed the fact that although she has been in the house many, many times and looked at the roof light she didn't clock how the reveal would have to be done because of the way it was positioned - it just cannot flair in all directions because it is set up between two 300mm deep beams. Same thing a few minutes later when she realised how big the flat portion of the vaulted ceilings would be. The structure in which it must fit has been there for a year or more but she does not see the implications of that and I just didn't spot she didn't get it even though we chose to flat it out much earlier in the build to give us some service space at the top of the house. This naturally works both ways so don't think I know exactly what is going on all the time - I get caught out too. So although we have worked hard on communication over the build we still have our moments. "What you want a light there? - I wish you had told me that 3 years ago and we could have built a different house. SO COMMUNICATE, COMMUNICATE, COMMUNICATE....

Probably more if you go the full architect route but if you have vision and are ready for hard, often relentless, work you will make it to the end. You will have A. The satisfaction of having done it. B. Much better equipped in all kinds of situations you will find yourself in the future - because you understand the challenges of constructing a home, you have grown in confidence with a wide range of skills and, C. There will be this artefact on the street that will be testament to your work for generations yet to come who will, if you build it to be light on the planet, thank you for it.

No it won't, but in conjunction with other things it can help with cooling.

Well I never thought I was that clever but maybe I am by comparison to some - oh that's how IQ works, now I get it 😂.

Then they clearly have no understanding of number.

I suppose there is a chance that you have hit the sweet spot? I wonder how the ASHP is cycling do you have any details of that? Sorry if I don't recall your upstairs temperature management systems but you, and others, talk about it getting a bit warm upstairs over the past heatwave. So I have been looking at cooling for upstairs in our build but I do wonder if some sort of stirring system to pick up air from just above the slab or push warm air down to the slab (EG simple convection) might be a way forward.

Leaf blower it into a shed or some such then scoop it up from there?

Some might say worst thing that happened, others might say the best thing that happened - but mostly nobody noticed which in itself was a shame but generally the way of things. ‘THE PAST IS A FOREIGN COUNTRY: THEY DO THINGS DIFFERENTLY there.’ L. P. Hartley. Which I guess is why building control is very different today. We are actually all over the place - and like @SteamyTea we sometimes move about a bit, none the less you are very welcome to THE forum for people like us.

Just show them the patent - ?

So he wrote it up and started a fad.
