Good Afternoon All,

That's me back from a 'jog' up the road and back trying to kid myself I'm not getting old - ha ha whom I kidding?Huh?

Now to see how SSE are applying the 'Fast Track' advisory iro battery storage add-ons since I last communicated with them - I'll certainly be telling them where they can stick their previously proposed 580+ fee.

I'm also now on the look out for another circa 1.6kW of PV to add to the 1.675kW I already have on this inverter........... mind as all four inverters have been showing flashing green LED's all day I'm not getting much out of the 5.675kW I currently have installed.

Regards

Richard

Good Morning All,

OK so I need to get these additional PV panels/ Growatt c/w battery and 'new' inverter installed 'officially'.

I have read SSE's rules and they clearly reserve the right, understandably, to inspect an install by an installer unknown to them. They have advised this will cost me the 580+.

I've downloaded SSE's energy storage fast track information - https://www.ssepd.co.uk/WorkArea/DownloadAsset.aspx?id=14149

It looks like the easiest route to take is to buy an SMA Power Control Module and limit the exported power to zero. It will certainly be a cheaper option at circa 130. It just means that I'll not be exporting energy which seems stupid.

Regards

Richard

Good Evening All,

OK so now I've read the SMA Power Control Module manual a little more closely I see I need to have some kind of 'ripple control receiver' - err some pointers would be appreciated. I've tried Googling and it really hasn't helped.

Regards

Good Morning All,

After yet more 'research', for which read Googling, I see that RRCR (Radio Ripple Control Receivers) signals are generated by the grid operator and cause plant to shut down so this is clearly of no use to me whatsoever. It would be so much easier if SMA used a simple CT system like the Immersun or Growatt!!

I appear to be running out of options I either just run things 'under the radar' or I put my hand in the air to declare the system and the other hand in my pocket and stump up the 585.

From self-monitoring this last summer I broadly kept within the 16A at all times but I want to add a further 1.6kW of PV at some point and this will definitely take me over the 16A limit on sunny summer days.

I've produced 768kW from the additional panels so far this year (two of the panels have still to get up on the roof and are still propped up against the steading wall). As I'm not sure how much of this was used on site or exported it is very difficult to value it. If I were to assume I made full use on site that represents a saving of 117 with my current supplier.

Fitting more will make better use of the Growatt but in outright economic terms it doesn't stack up especially if you add the 585 commissioning costs. I'd be looking at around a 1200 investment for panels, mounting materials, cabling and commissioning costs for the extra circa 1.6kW. If I were to assume that doubling this PV extension doubled the return I'd be looking at making say a further 100 a year 'saving' which allowing for electrickery prices increasing at 5% means a circa 9 year payback

Prompted by a query the other day I re-worked the Powerwall2 possibility and even allowing for the same 5% year on year increase in electrickery costs I was still looking at a 12 year payback and that wasn't even factoring in battery or solar panel degradation.

There're other calls on the money currently so I think I'll keep my ear to the ground for some cheap second hand panels and just leave things as is for now. Biggest operational issue is addressing the state of the cells in the Growatt battery pack. I need to look at removing packs and conditioning them.

Regards

The solar edge HD5000 I have just had installed can control the export in the manner you desire.  It needs a module hooked up to your mains that is essentially a ct clamp and rs485 to the solar edge inverter.  It monitors the export and limits the production according to your setting.

Iain,

As I understand it this device would need using in conjunction with a Sunny Home Manager 1 which adds to the cost or you could just buy a Sunny Home Manager 2 outright at 616 and we're back to just getting SSE in for commissioning at 585.

When you turn on your electric cooker and the heat pump and the,,,,you are using way more than 16a. So what comes in can go out, what were you saying about the radar.

rogeriko,

I'd agree with you entirely. When we had our pumped electric shower it alone in simple terms (from W = IV) was 39A.

As an aside I'm actually surprised how little energy the heat pump takes. The total energy consumed in the house yesterday, according to the Immersun (usually within 4% of the 'real' figures), was 46kW or 1.92kW/ hr with a peak of 4.1kW. We had a peak reading, at 0600 this morning, of 5.3kW as the heat pump kicked in to give the DHW a blast of heat (taking advantage of the Economy 7 before it expires at 0700) and I set the washing machine and tumble drier.

The 'flying under the radar' reference refers to the fact that my DNO are unaware of what is connected............

I've just received some more 'approved' labels to stick on the various locations to make it a more 'correct' installation.

Regards

Good Morning All,

I've taken the plunge and acquired another 1.5kW of solar panels. Theoretically this means I will now have 1.28kW + 1.28kW + 1.44kW + 1.645kW + 1.5kW = 7.145kW, but allowing for 1% deterioration per annum this more likely becomes 6.73kW.

It will be interesting to see how the Growatt behaves this year coming.

I'm still trying to get my head around the Sunny Home Manager 2.0. Take the two following paragraphs;

Using an SMA Energy Meter, the Sunny Home Manager monitors the active power that is fed into the utility grid. If the active power feed-in exceeds the prescribed limit, the Sunny Home Manager limits the PV generation of the inverters accordingly.

The Sunny Home Manager 2.0 monitors all energy flows in the home, automatically recognizes potential savings and enables the efficient use of solar energy in the home. As of April 2017, the new Sunny Home Manager 2.0 combines the functions of the Sunny Home Manager Bluetooth and the SMA Energy Meter in one device. This makes intelligent energy management even easier and less expensive.

The first paragraph is taken from the manual for the Sunny Home Manager 2.0 and tells us that the Sunny Home Manager 2.0 requires a SMA Energy Meter to monitor output to the grid.

The second paragraph which is part of the blurb surrounding the launch of the Sunny Home Manager 2.0 telling us it integrates the function of a Home Manager and an Energy Meter.

Either the Sunny Home Manager 2.0 does integrate the functions of the two previously separate devices or it doesn't and SMA's own printed words do not absolutely clarify the position.

Regards

Richard

Good Evening All,

I'm slowly getting my head around what will be required to implement the SMA Home Energy Manager 2.0.

I'll need a new consumer unit on the far side of the outbuildings to accommodate the width of the SMA unit. Fortunately I have a fuse upstream of the DNO one and on my side of the meter so can isolate the incoming supply to carry this out.

I will then need to run (another) CAT5e/ 6 cable from there to this side of the steading en route to the router in the house. I will also need to run another CAT5e/ 6 cable out from the router in the house to the SB3000TL-21 inverter. It looks like I'll need to dig up the drive to put in some kind of conduit to run the two cables across to the Utility Room. I currently have one cable run from above the heat pump up to the router but will need to run another one.

I'm sure things could be easier.............

Regards

Good Evening All,

I've been out and done some measuring and reckon the cable out to the inverter needs to be 65mtrs to be on the safe side and the one to the consumer unit needs to be circa 90mtr as it has to run up in the house roof and along and down again to reach the router. I've ordered cables now. I can hardly wait to get back in the attic spaces again.

The main incoming CU only contains a 100A RCD and clearly has space to accommodate the SMA device which makes life a little easier.

The SMA Sunny Home Manager 2.0 has been ordered.

I recently bought 4off Sunclix connectors to connect the new panels.

I've ordered yet another DC isolator switch.

The PV panel roof mountings have also been ordered.

I'm back up to Lerwick again shortly so the various bits will arrive at the flat whilst I'm away. The panels will be delivered when I know I'll be home.

Regards

Richard

Good Evening All,

I'm sure we'll get this rig moored up eventually, that's us now waiting on weather......

Still trying to get my head around various things re implementing the Sunny Home Manager 2.0.

As there may be occasions where there maybe more than 63A flowing i.e. charging EV and heat pump, washing machine, tumble drier and dishwasher all running together I've ordered a 5A output CT so that the Sunny Home Manager 2.0 can be wired accordingly.

I'm also out of ethernet sockets on my router. Currently I have:-

1. the desktop computer
2. the Immersun
3. the heat pump
4. Vonage modem

so adding the Sunny Home Manager 2.0 and SB3000TL-21 inverter exceeds the four sockets I have. Google to the rescue tells me I can adapt an old router to become a switch so that is the route I plan to follow currently.

In theory the Sunny Portal set-up could allow me to dispense with the Immersun as I understand it.

As I'm on shift until 0600 in the morning the highlight might be seeing the blood red moon in the early hours.

Regards

Does your SB3000TL-21 inverter already have the webconnect data module to connect to your router ?

Otherwise its another thing to add to your shopping list.

I think the part number is SWDM-10 and about 130
