Richard, I have PM'd you in more detail but for the benefit of others, if you use a second SMA Energy Meter you are instructing the SHM2 to solely use the second Energy Meter data for ALL generation data therefore the SHM2 will ignore the generation data received directly from the speedwire enabled inverters (v21's).

The point of adding the second Energy Meter is for Sunny Portal to correctly display and report your total PV generation and correctly work out your house consumption figures.

Good Afternoon All,

I have had a number of offline communications with nowty who has more experience with this SMA equipment and have had to change my plans as SMA's software won't allow me to do what I want although I can still extract the information I want installing the SMA preferred (for which read the only) way.

The SMA information is challenging. You may recall I commented that the installation information for the SHM 2.0 didn't specifically refer to you needing to tell the software you had a CT fitted whereas the same style of installation information for the Energy Meter does.

I now need to re-run the one CAT5e cable from the outbuilding CU to the Growatt location as this is where I'll be mounting the ethernet switch. I'm hoping that the Energy Meter will fit in the Outbuilding CU as this will simplify things - (it didn't as it was a Memera CU with different mounting rail........).

Persons of a delicate disposition should look away now as the attached photo's show how to take two perfectly functional pieces of equipment and dismantle them to their constituent parts.  I can advise that in addition to nowty detailing that the 4.8kWh Growatts contain 252 cells in a 14 x 18 array I can report the 2.7kWh ones have a 7 x 20 array giving a total of 140 cells. Unless anybody feels they might need empty cases or BMS PCB's the pictured detritus will be getting conveyed to the recycling centre tomorrow.

The Growatt and existing 4.8kWh battery will stay 'active' until the SI 4.4M-12 is installed

The SB36000TL-21 was collected by Parcelforce today.

Time to go out and do some more.

Regards

Richard

Good Evening All,

That's me in to do something for dinner before going back out again.

The attached photo will show I've now patched in the Energy Meter adjacent to the Main PV AC Isolating Switch. Using 6mm2 T&E is probably completely OTT. Taking onboard an observation made when plumbing in the SHM 2.0 I've also incorporated an isolating switch.

One day when I have nothing better to do (ha b****y ha) I'll take everything off this part of the outbuilding wall and start again as the electrical gubbins just keeps expanding and a 'start from zero' installation is required.

I've had contact from one member - fear not none of the 'scrap' Growatt bits will find their way to the recycling centre as soon as tomorrow - more likely to be years if truth be told.

I've dragged the four battery packs inside and later this evening I'll get a meter on them.

Regards

Richard

What are you doing with those batteries?  Building your own charge / discharge system, i.e. your own designed battery storage system?

Ouch, they not even symmetrical are they. help
So each cell container must have 10+10 in series ?

ProDave,

I'm aiming to build up a battery set-up along the same lines as nowty albeit smaller.

nowty - may look at cell make-up shortly - I'll have to go out and rescue my tools now.

That's the Energy Meter up and running, connected to the internet and recognised by Sunny Portal. I need for daylight to come up now and check that it functions as intended - i.e. gives me the Total PV Generated figure.

Regards

Richard

Are they 18650 cells in there? Pack design looks very similiar to these:

Tiff,

No they're the Swing 5300 type as nowty first identified. They are a dedicated cell around twice the size of 18650 I believe.

Good Evening All,

So there I was pleased as punch as the sun sort of came out this morning and the Sunny Portal system showed the PV production courtesy of the Energy Meter like what it was meant to do.

Everything was going well and then as the cloud cover broke so did the PV output, minor panic set in and I went outside to see what I could see.

The MCB for the Energy Meter had tripped and the inverters had all tripped as well.  I couldn't see anything obviously wrong so reset the MCB and everything seemed to be OK (note sun had gone back behind the cloud again).

A short while later the suns comes out again and the MCB trips again.  Much head scratching.  I convinced myself there must have something wrong with my wiring and decided to re-wire the Energy Meter using a 'spare' CT so that's what I went and did.

It was nowty that asked me the question as to what was the rating of the MCB.  Well of course a 6A MCB is likely going to trip with anything more than 1475W flowing..........

It had simply never occurred to me that it was a simple as the MCB rating.

Still I'll know for next time.

Meantime the SB3600TL-21 may, or may not, be at the Parcelforce depot here in Aberdeen, I did try phoning them but the lady in Glasgow (I thought I'd selected the local depot on the phone menu) couldn't tell me exactly where it was as it may have been handed over the Royal Mail - I don't know about other parts of the UK but at Altens they occupy the same building. Just waiting for Kate to get back from work so I can drive up and grab it as Plan A (the one where I go back to work on Monday) became Plan B (where I go back tomorrow).

Late addition - So Parcelforce have handed the parcel over to the Royal Mail this morning and, one assumes, my postie will attempt to deliver it tomorrow. I have paid 56 for this next day service. In the meantime APC were able to move two Growatt batteries, weighing a third more than the inverter, inside 24hrs for less money.

Regards

Richard

Good Morning All,

So I'm minding my own business in the flat in Aberdeen when the mobile rings, 0344 number so I don't answer. Phone pings and there is a Voicemail message from the Parcelforce depot in Aberdeen.

Apparently Royal Mail had passed my package back to Parcelforce and they were going to put it on a wagon out to the house today (interesting I thought as Saturday delivery is 7.50 extra and I hadn't paid it) and was given the local depot tel. no. to call back.  I did only I didn't get through to Aberdeen and whichever location it was promised to deliver a message to the Aberdeen branch advising that I would come and collect it.

I have just come back from collecting the parcel which was clearly at the depot last night when I turned up to collect it..............

Still the sun is shining so there is one positive, as to whether my son't team will win at the rugby later is another matter.

Regards

Richard

Good Evening All,

We should be berthing in Aberdeen and tomorrow and I should get back home on Friday to hopefully find that various items to facilitate the next stage will have arrived.

Firstly I'll be shifting the SB3000TL-21 from Growatt charging duties to replace the two SB1700 as previously detailed.

Secondly I'll be installing the 'new' SB3600TL-21 on Growatt charging duties.

Thirdly I'll re-install the Energy Meter back to being adjacent to the PV AC isolator switch (with a higher amperage rated MCB this time).

Fourthly I'll look to start pre-wiring for the arrival of the Sunny Island 4.4M (due mid-April).

I'm currently negotiating over a 5kWh Growatt battery..........

Some more, new, cheap Solar PV panels should arrive early next week adding 490W to the current 2.895kW string and the 190W panel for dedicated generator start battery charging.

I did wonder about seeing if I could operate say 8off Trojan T105's off the Sunny Island as nowty seemed to manage running FLA and lithium in parallel but let's just address one thing at a time. There is also something to be said for keeping things simple?

Regards

Good Afternoon All,

I'm having a two chocolate bar afternoon tea break - there's throwing caution to the wind......

Well that's the 'new' SB3600TL-21 put up in place of the SB3000TL-21, firmware updated, recognised in Sunny Portal and then altered from G83/ 2 to G59/ 3. On things of minor note that although the inverter was fitted with the SWDM-10 communication card it wasn't pre-fitted with the correct two hole cable gland, I guess it came with the original outfitting but not fitted as it wasn't used.

I have a whole host of bits that have arrived whilst I was away to facilitate the various things I need to do ahead of the Sunny Island arriving. The Postman had to re-stack things in the post box yesterday as it was getting a little full with haphazard tipping in of packages.

Trying to decide whether to replace the 2off SB1700's with the SB3000TL-21 next or put the Energy Meter back where I wired it the first time now I have a 32A MCB.

Still negotiating the Growatt 5kWh battery pack......

OK - late afternoon addition, that's the 2off SB1700's replaced............. I even remembered to put the inverter back to G83/ 2........

Regards

Richard

pantsmachine,

On the chocolate side of things only Cadbury's Dairy Milk - I'll spoil myself with some dark chocolate and marzipan occasionally.

Most of my electrics need re-running BUT there shouldn't actually be a board at all which is why all the stuff for the extension is fixed direct to the stonework.

The dangling 6mm2 T&E cable in the upper part of the picture is a part of when I re-worked the inverters and had them all feed back across to the far side of the shed via the old incoming SWA mains cable to keep the line losses down. Currently the inverter on the PV extension is about 30mtrs of cable away from the incoming CU but the cabling runs in the opposite direction to get there so to speak. There is probably 90mtrs of cabling (between 6 and 16mm2) though the way it is currently wired.

This was also partly dictated by the desire to pass all the Solar PV production via the Immersun CT system.

In a perfect world, a large budget, and the desire it could all be tidied up.

Even the number and length of Cat5e cables bought recently could have been streamlined if I'd thought to use a switch in the first place.

One day I'll maybe sit down and create an overall plan........

Regards

Richard
