Air to Water Heat Pump

I am not suggesting that the battery management system should be user accessible, in fact ways of controlling that management interface are essential, though we are all aware some restricted or controlled interfaces do have a habit of being opened up, not always the way everyone might want.

However, a user interface to the building management aspects might be required if you want the user to have some sort of control over time of day, the prioritising a power sources etc. If you throw in power costs management , ‘charge up now for only 50% of normal’ the game really could change. Would you need an interface to an external system, etc.? You would probably want to ensure that was not given external access to the battery management functions, that is where the clever stuff would be needed. Build it in at the start and you should be fine. Get the set up built by Wyatt Erp’s Nemeses 2018 Inc and you are on your own. A typical IOT, (or more realistically named IDIOTIC Internet Direct Integration of Threats Including Chaos) device should not apply for the role.

Looking back a few years I could sit at home and log into all sorts of systems in other countries and do all sorts of things that I would seriously hesitate to have access to these days.

While we share a more or less common view that there are some things even semi skilled users should be totally bared from accessing we are only expressing that stand point in different words, not different philosophies. Do many dismantle their gas boilers, TVs or PVRs and they have far less potential for harm. Besides one access  already being illegal.

Steve, my left shoulder was giving me gyp all night and into most of today. Yesterday I had two more vaccinations to boost the activity that my spleen used to provide: Meningitis B and C. One in each shoulder: whilst the right one is unbothered, I kept turning onto my favoured left side last night and waking up with pain in my left. Combine that with the Prostate-inspired 3x toilet visits per night, and I seemed to be awake all night, until awoken from 2 solid hours by my dear Gert. I recall having jabs for various Eastern postings during Army service, and it was always the left side shoulder that reacted worst. Chemo again tomorrow, one more week after that takes us up to a week’s holiday in a quiet Suffolk village lodge. I am looking forward to that. I like Suffolk and Norfolk.

Bob,

I hope it went well.

My wife’s chemo went well with a cherry on top. She met a few who are now on tablets have previously opted only for radiotherapy and not been a clear as they might have hoped. Hence the ongoing battles with tablets as their troubles have spread and cannot be solved, only ‘managed’. She is glad she did not opt to avoid anything to give herself the best chance for the future.

I am glad she does not have to drive at the moment as one treatment contains enough alcohol to put her over the limit, there are warnings on that and the other drugs demolish boundaries while giving almost reckless drive to do things and talk. She was up at 05:00 this morning rushing about and not always getting it right along the way.

There may well be the cell level monitoring you suggest but tbh I did not find it during my delving. Over-arching all this of course is a very simple user level interface, and shutdown/start-up controls. The house trips ‘should’ protect anyone working on the house circuit, but it is nice to know that there are ways of powering down a 6KwH box just in case!

I would be stunned if any of them had no monitoring. I even found a crude version in a NiCad battery pack from years ago. OK there was no feed back to a ‘main’ controller. Later on I found that there was a degree cell level monitoring via close coupled bit of electronics that tried to look after its own small bit of the bank, but replicated across all other bits. I have not studied more recent packs/controllers, though the mutter from those colleagues who still earn a crust suggests that they expect that level of management and reporting from the kit they manage and install – most of which is a bit bigger than UK domestic. However, at least one does also have tentacles into the hotter, more humid parts of USA where comfort still rules even off grid.

I don’t understand why, when all new builds seem to come with solar panels, they don’t also have battery banks built in, and home electronics don’t run from 12V etc.

Surely it would be safer, and bulk buy discounts from the big home builders would make it affordable?

That’s what I think. I’d go further, require all new builds, where possible, to have PV(solar) and id make batteries probably optional, as they are quite expensive still, but mybe some tax incentives

Also any house sold, incentives the sellers to have PV and maybe a battery. If this happens withing 40 years, we’d probably need one main power national station ticking over feeding , a hand full of battery substation, when the networks home PVs arnt keeping the sub stations batteries topped up.

Then we would be a self sufficient nation. Not needed in to import power from abroad. One less thing to have to go to war over. Oh wait, that’s the main reason we do it. Oh and to keep selling weapons and systems to others.

I’m sure we’ll find a new war reason. Water maybe. Yeah that’s good enough. Water.

 

Also there is studies now that think the EV cars will one day act to in fill any dips in try grid.

Ive just thought of a great video from an real EV ran closed estate. The guy from scrapyard wars hosts it. I’ll try and look it up, may fail thou as it’s late

I couldn’t find the exact video, but this is the channel. I suspect many here will like it. Scrap yard ways guy, and 5th gear guy. (I’m great with names)

The PV Solar Business is currently stuffed with cowboys and chancers. There are many complaints on MSE about various companies, some taking deposits and either doing carp work then demanding payment, some doing carp work after taking deposits, then being unreachable when not returning to finish up. Others not surveying roofs properly, because they won’t employ qualified surveyors. The resulting problems are often horrifying and customers who are the victims struggle to get legal help to resolve it.

Government needs to get more involved in this by regulating it properly. That’s where a requirement for all new builds and after builds to have soalr built in would be valuable but need to work properly Steve, but with more teeth than some of the current Regulatory Offices have. The sticking plaster that is Utilities Regulation in this country, is mostly ineffective and weak.

Bob I think you should probably put your cowboy statement in the past tense, as today you cannot get a Government FIT payment unless the system has been specced and installed by a FIT qualified installer. link

That said it is still a little bit of a buyer-beware area in that it is possible for a qualified installer to spec up a system to older standards that work but not quite as efficiently as more modern kit. For example there is nothing wrong from a FIT standpoint with speccing up a U-Boat style lead-acid battery system that would fill your garage in the place of  a much smaller Lithium battery system. (such a lead-acid system might actually be the optimum for a farm set-up). The actual installation has to be signed off to the usual electrical standards for equipment that taps into the box outside the consumer unit so no real room for cowboys on that side

The door-knocking survey cowboys are something else – closer to roofing con-men.

[Bob Williams]

Well the complaints are still coming in Ed, so something is still wrong.

I am inclined to agree with you Bob on this one. Some cowboys were still operating very recently, one called me a month or two back though I also agree with Ed. It has long been the case that you will not get FIT if the installer is not registered or the paperwork is not up to standard. The cowboys do not care, they have a sunset to ride into and that is your problem. I do feel some of cowboys might have moved onto fitting SMETS 1 ‘SMART’ (i.e. rather dumb) meters now.
