It seems to me that for that money, all they're going to do is send an Engineer to your property and fit a bigger DNO circuit fuse at their side of the Henley Block?

It does beg the question of actually how much more could you put down the wire if they're going to bother to charge you for someone to come out and do that?!

Good Afternoon All,

Had a call from Moixa's office in Manchester the other afternoon. We discussed the possibility of fitting one of their battery systems. Had an EM this afternoon with them telling me when he'd been speaking with me he didn't realise they didn't have anybody local to me............

I really despair of organisations in general  banghead

Good Morning All,

I've jury rigged my 7off PV panels, i.e. propped up against the steading back wall and hooked up the Growatt under controlled conditions, i.e. making sure I'm not exporting more than I'm allowed  Grin

As there isn't sufficient sun for long enough in the day that is said very much tongue in cheek.

There is little fear of the Growatt battery getting charged (currently sat at 10%) as what little sun we're getting, once it rises above the ridge, any excess energy is being diverted by the Immersun to the EHS immersions. On a positive note we've had a couple of short periods where the heating system has used the energy in the EHS during the last couple of days.

I still intend mounting the panels on the steading roof although a solution allowing me to be able to leave them connected full time has yet to be arrived at.

Regards

Good Morning All,

That's mountings for the 7off PV panels ordered.

The inverter/ Growatt are now connected up via a DC and AC isolator with an Elster generation meter (as I had a 'spare' lying around).

I see, from doing some Googling, that the likes of an SMA Sunny Home Manager 2.0 coupled to the likes of an SMA SB3.0-1AV-40 could be programmed to limit the export from the house to circa 3.86kW/ 16A limit?Huh  

As I understand it a Home Manager system 'Speedwire' needs to be hard wired. I knew there was a reason I ran a second CAT 5 cable from the Utility Room roof space (the first was to connect the heat pump to the router on our landing). I'd need to run another CAT5 cable from the incoming point on the far side of the outbuildings (I'll be able to secure it to the one already in place for the Immersun).

How many CT's can you have at one point? There will be:-

1. the Immersun
2. the Growatt
3. the Home Manager

Thoughts welcomed.

Regards

Richard

CT = Current Transformer?
I wouldn't imagine there would be any problem with them interacting, but I'd be inclined to leave a bit of space between them just in case (if you've enough room) - just a few mm of air would reduce any stray magnetic field considerably.

I guess it depends on the response time / sampling frequency of the control systems behind the CTs?
I'v been told PV diversion & residential BESS systesm can happily coexist, however (if I had one) I would prefer the BESS to take priority over the PV diversion as it's displacing electric kWhs rather than gas kWhs (5x the price!)
Sorry can't be of more help but look forward to any other responses .....

Good Afternoon All (Well it is the afternoon here down in the Red Sea),

After some more reading I believe the Sunny Home Manager system will work with the likes of the SB3000/ 3600TL-21 series of inverters as they have the power reduction capability??? This reduces the potential overall price of implementation as I should be able to get a second hand machine off everybody's favourite commerce site.

Yea, it works with the -21  but not the -20 series. If your going down that route you should have used the sunny storage system rather than Growatt???

BTW. the latest generation of sunny home manager in now integrated with the smart meter, so the smart meter fits into the modular CU and that meter module also contains the home manager. It looks a bit strange as you have an ethernet cable plugged into the front of the CU, so you can't close the dust cover......   Also a  new version of Sunny Storage charger/inverter is comin out soon and will increase the charge/discharge rate to 6kw..

Growatt Shine Limit does the limitation, and if you already have a growatt battery system this is probably a better bet.

No experience of it, but it appears to use a number of pre-existing parts( Shine Link and the Growatt SP-CT, which you probably already have if you have their batter solution)

Westie,

The Growatt came at a good price and I was able to get the battery transported 'free' by a fellow Land-Rover owner who brought it up North. As I'm sure most people will be aware on here shipping lithium ion batteries is a nightmare.

I need to keep the cost down so I need to buy everything UBG. Unfortunately the Sunny Home Managers, 1.0 or 2.0 don't appear to fit that category currently  Sad

I'll keep my eye out for a UBG SB3000/ 3600TL-21 and bide my time. I can't see the Home Managers coming up cheap though.

sam_cat - thanks for the link to the Growatt product, I wasn't aware of it. Now to go and see what prices are like.

I do still need to challenge SSE over this 585 fee.

Regards

No problem,

I suggest giving Growatt a call, as you already have all/most parts that are needed.. Just not all in the 'ShineLimit' package. I bet its just software in the box Wink

Doing a touch more reading on the ShineLimit option, found this:

http://ginverter.com/UpLoadFiles/20161028/Growatt%20ShineLimit.pdf

Quote
ShineLimit is composed of ShineLanBox (calculation & control), ShineRFStick-wireless transmission unit and SP-CT(measurement)

All the parts are readily available via auction sites, the ShineLan Box handles all the clever work... If your battery solution is the one that I think it is then you already have all these parts.
