Different crowd, similar name, no knowledge sorry.

What about the other crowd you mentioned?

I only knew them from doing underfloor. Not over impressed. Loops too long and didn't zone each room. Sort of cut price job, don't know if those savings made it to the customer.

The best quote that i got so far for a hybrid inverter and 2 x 2.5KW battery built-in,all cables and management inside, comes at around €5,000 ex VAT delivered.
No installation so far quoted and trade price.

Beauty of THIS system is that it takes the arrays mounted with the cabling in series so no changes required at that level. Docs HERE .

What do you think !?

What will your final system look like ? what do you think it will cost?

Dunno yet...still looking around.

I have around 5-8KW diverted to immersion on an average weekday.
I guess that could go to a battery, 5KW capacity.
The 5KW battery could be depleted from 6pm to 8am,when i do around 500Wh x 12h = 6KWh....still not enough !

Sorry, I don't get what you are talking about.

Do you have an existing pv system which you are now looking to add a battery to ?

If so, what is the existing system dimensioning ?

5kWh (please correct your units!) sounds perfect so, means you will maximise your use of it.

My 5KW installed power PV array cannot "justify" a 5Kw battery...end of story.
The manufacturer gives 10 years warranty or anumber of charging cycles BUT not if you keep doing deep cycles.

If my outgoing is 500Wh by 12 hours off-sunlight,i will need to stop using the battery at around 40% SoC,otherwise i massively reduce the health of the system... therefore,i can extract maxim jouice of 50-60%, giving a 5KW x 60% = 3,000Wh...over 500Wh,autonomy of 6 hours ?!?

500W is a fairly hefty base load while you're asleep. It would be better to try and reduce that if possible first before sizing your battery.

unkel · 16-10-2018 09:40PM

My base load is well over 1kW atm

EVs don't charge until you apply at least 6A (1.4kW). So not the car!

Correct...

I do switch off few appliances but these below are the critical that needs left ON:

Heat recovery,setup dynamic,1-2 speeds
Heating controls
Boiler
UFH pump
Water softener

CCTV
Alarms x 3
2 Servers/PCs
Routers x 3

Heat Recovery in the greenhouse 24x7

What else i can power off,i do it already.
Thats why i consider doing the maths / homework before jumping at the system and adding numbers.
There is no way that a 5KW battery will do me justice here... i guess going with more than likely a 10KW capacity... which goes to amost €6-7k.

Aye, but you wouldn't get your EUR 500 back

Is that what it costs?

Edit - Found it on Myenergi Website - https://myenergi.uk/product/eddi/

I guess I never seen a breakdown of my install so never checked the prices of anything

unkel · 17-10-2018 10:07AM

Yeah about €500 installed. You need not worry though, you had such a good deal on your system

And of course the more expensive / the bigger the solar PV array you are installing and the more hot water your family consumes, the more it makes sense to invest a further €500 on top of your solar investment into a diverter. It makes very little sense on a 7 panel system though. Cheaper to just give away the excess for free!

17-10-2018 06:13PM

€500 for a diverter?! :eek:

€200 reconditioned!

Where do you source these parts reconditioned?

Ebay.co.uk

Doesn't seem to be any atm, bar a very old one on auction.
Have Immersun gone bust again?

Hi,

Got my summer electricity bill...
Despite pumping over 700KWh of juice on the grid,i got hit with a huge bill for around 700 units.
First think that i've done when i saw the bill... !?? Ordered an import / export meter...i had issues before with analogue meter i feel my current one's goes crazy with the currents and sensing the correct flow of electrons...

I've decided to go with a 10KW system like this one HERE.
Love the fit out,intelligent charging and reports,smart controls of the appliances.
Not sure if it can be setup on "pure hybrid" mode in case grid goes off so that i can use speciffic outputs for lights, lets say.
Still waiting for suppliers reply to my FAQ.

Anyone uses this type of system !?

Have you a price for this?

Not yet public...too many variable and is not available until end of the month.

You bought €98 worth of electricity units from the grid over the last 2 months.

rolion wrote: »

So you decided to spend well north of €10,000 to add a battery to your existing system?

You are batsh1tcrazy, rolion

FWIW, I was quoted €6,487 incl vat for a 2.5 kWh Sonnen battery in July. I considered it a tad expensive....

rolion · 20-10-2018 11:04PM

Who said anything about prices !??

I just want my bills to get near zero or ... two digits.
I am exhausting my consumption vs generation options and i want ... lower bills.

At the same time... i'm considering,looking at options ,nothing comitted at this moment.

You were asked, but you were shy responding. I did a quick google and I didn't find much, but what I did gave me the impression that to add one of those 10kWh batteries to your current system would set you back well over EUR10k in total. Possibly even a lot more than that.

Am I wrong?

Yes and no.
NOW I am really pissed about my summer bill...injected more than I consumed and got a bill of 180 quid to pay... I want that as lower as I can even if I have to be ,quote you "batsh1tcrazy".
If I have to look at figures, I will not gone the PV and tubes path...
Keep you posted.

On another tone...I highly recommend to all of you that thinks to go with PVs to replace the exiting meter with a import/export type even if it cost you TODAY 340 quid cash....not going in to conspiracy theory here.

unkel · 20-10-2018 11:56PM

Would you just answer the question and let us know how much it would cost you ballpark to have that 10kWh battery installed?

Why? Paying for the install of an import/export meter would add considerable time to the already very, very long ROI / pay back time for a solar PV install. Once you install your Sonnenergy system, your pay back time is about 250 years. If only I was joking...

My Sonnen system is fcuking here on the internet or...somewhere in a warehouse in Germany... or a boat in China Sea...

At the moment,it looks the most plausible and effective battery system available on the market and working under Irish regulations. Complete plug and play and does all the things that I expect (Still waiting for hybrid function confirmation).
If I managed to disturb "the force" for some local distributor or anything like it..is not going to work because like you said is very expensive and not worth it.

I do not know the cost adding Paddys taxes and so on, i found it on the continent and is not available for selling here yet. I am not a sales man, not a dealer and I definitively not working under commission. So stop asking questions at which I do not know the answer.

Related to meter...can't say too much rather than I advise to pay the charge and get a proper import/export meter to avoid any technical surprises .I can't comment any more on the matter due to legal reasons.

As well, keep well and enjoy the Sunday...and more Sonnen for you !

The handy thing about this video is that you can tell when the guy is saying something that is wrong because his lips are moving. What he is saying is just not correct.
