Hi Richard
I had a lot of issues with dropped communications with my inverter (SB 2.5) when I fitted it.
After many phone calls to the helpline I had to set up "Port forwarding" on my router. I have had minimal interruptions since.
I also had to fix the Inverter IP address on the router to a static one.

Iain,

Thanks for this, something to look into more closely. There is some stuff in the manuals about setting things up which I probably need to go through in more detail.

I'm just glad I'm moving in the right direction although still some way from where I wish to be.

I may contact you when I get back.

Regards

Good Evening All,

I fibbed when I said there wouldn't be anymore from me.........

Lots of thumb twiddling going on out here as it looks like we won't be starting this here rig move until Monday so........

I've had two old Gunson G4106 battery chargers (along with two desulfators) plugging away (on Economy 7 only) my 4off Trojan series wired T105's (for starting the old diesel generator) for quite some time now and have been meaning to do something more environmentally friendly for some time but just never quite gotten around to it.

Having taken some advice from Scruff I'm planning on buying a Morningstar charger device and a dedicated solar panel (190W??) to take over the charging duties in the none too distant future. There is no economic benefit in doing this but I'm sure I'll get a nice warm feeling knowing I'm doing a little bit more to reduce my electricity consumption and thus the impact on the planet - well that is what I'm telling myself anyway.

Regards

Richard

Good Evening All,

I note the post elsewhere about wind having produced over 1/3rd of our electrickery in the last week. It has also been a good week on the solar front, certainly up in our neck of the woods. I've attached a picture of the Immersun results from the last week.

I've also attached a picture courtesy of the whizzo new software available for the heat pump showing when the heat pump compressor was running and when not. The combination of Solar PV and Solar ET being responsible for that.

Having access to the information I now do it is a little disappointing to see that over the last 2 nights at least the Growatt has discharged at a relatively low level, certainly no more than 50% of the house demand and, as far, as I can tell, stopped discharging at 50% SOC. This is leading to more Solar PV being exported than needs to be the case. It would be interesting to hear from other Growatt users.

It will be interesting to see how nowty gets on with his revised installation as I'm aiming to go down the Sunny Island route as well.

Currently trying to track down a new linear actuator for the tracker....... an outfit in Spain appears to have some if only they'd respond to an EM........

Regards

Richard

Good Evening,

It has been suggested that I replace a part of my existing system based on the 80W panels with new larger more space efficient ones. It is certainly a different 'take' and not one I had considered.

The 1.28kW ROC/ FIT part of the install consists of 16off Chinese 80W panels purchased and fitted back in 2010.  These are currently fitted in the middle of the long steading roof but are not using all the available space.  These could be substituted by the 5off UBG Trina 250W panels I've recently fitted meaning I would be able to remove all 16 of the Chinese panels.  This leaves me with a space some 6.1mtrs by 2.85mtrs to utilise.

I have already committed to buying 10off 245W panels along with a 195W panel for battery charging.  At 1.652 x 0.994mtr I can fit three in landscape and 5 in portrait and still fit the 2off BP380U panels on the end.  This would give me a near 800W improvement over the current install with 7.575kW in total.

I'm still considering this option. It I go ahead I will be selling the 16off Chinese panels to offset the costs. Additionally, as I will be substituting the 2off SB1700 with the existing SB3000TL-21, I will be looking to sell both of these as well.  I will post a For Sale advert to gauge forum interest before heading for Gumtree and a well know internet auction site.

Regards

Richard

Isn't the ROC FIT system based around the panels, they were the items that were registered.
I found this out when I replaced my inverter..
There was no issue replacing an inverter but would have been more complicated to replace the panels. It was those that determined the size of the system.
I think the only way round it is if the panels get damaged and the same replacements are no longer available. Then the FIT data base has to be altered. Not sure how easy or possible that is.
Then there is the possibility of loosing over 50p/kWh income from that system.
Can you not move them to one end? Even put them landscape and double them up. Then add the others at the end of them?

Iain,

I knew things couldn't be that simple. The panels concerned are the ROO/ Fit ones so only paying 11.51p rather than the 52.75p.

I'll send a PM.

Good Evening All,

The 1.28kW ROO/ FIT installation generates circa 110 a year in subsidies. Historically we have also used around 60% of generated power on site so there is a circa 85 saving in imported electrickery - total benefit circa 195.  The question then needs to be is replacing it with 1.96kW of new panels a viable alternative to 'losing' the ROO/ FIT status on a simple financial basis?

The 1.96kW of panels would generate 1467kWh rather than the 958kWh the ROO/ FIT does, allowing for the same 60% on site utilisation they could save 132pa at best. It would take 90% on site utilisation to reach financial 'parity' and that simply isn't going to happen without more battery capacity as a minimum.

The new panels obviously have cost me and it is likely that if I sold all the 80W panels and 2off 245W panels I've just bought I would anticipate that side would be just about cost neutral. If I stick with what I have then I go back to selling the panels I've bought and use any 'profit' towards more battery capacity.

I think I need to acquire more battery capacity first to maximise the PV power I have as I already have a second Growatt SP2000 unit.

I also don't want to draw too much attention to my current activities.

On reflection a case of letting sleeping dogs lie a little at this time.......

Comments welcome.

Regards

Richard

Then talking about them on a public internet forum might not be the best idea?

Good Morning All,

Currently back home as the job I'm on is on hold due to wx forecast.

I've currently got my slightly bemused head on. I've just booked the courier to collect the well known internet auction site sourced SB3600TL-21 what I bought and am trying to work out the Parcelforce 24hr Next Day Service.

If I pay an additional 3.10 Delivery Guarantee payment (Parcel due for collection tomorrow and therefore delivered by the 22nd to meet the definition of 'Next Day') then I only get a refund if it isn't delivered by the 25th - doesn't that make it a 4 day delivery service and not next day??? If it arrives on Friday I'll look to get it fitted over the weekend.

I've committed to buying an SMA Sunny Island 4.4M-12 and have secured some Growatt battery packs. I'm not even going to try competing with nowty (in terms of capacity as I don't have the Solar PV required) but I will configure the batteries ex the Growatt's in a very similar way to him.

I'm looking forward to having everything under the SMA (single) roof for much better control as previously mentioned.

I'll keep reporting as I go.

Regards

Hi
If you went to use parcel force it is roughly 1/3 the price if you book it through Parcel Monkey. Exactly the same service and even the paperwork is the same. I suppose parcel monkey is a broker but it is a good discount.
Have used it 3 times with no issues.

Iain,

I routinely use parcel2go.............

One problem we have is our location, the minute we put in the house post code a whole host of services 'disappear' from the screen. This is why I frequently have things delivered to the flat in Aberdeen.

Good Evening All,

Well that's two more Cat 5E cables run and I've screwed a CU to contain the SMA Energy Meter (EMETER-20) to the ROO/ FIT inverter mounting board. I'm going back out after dinner to start wiring this CU up.

The wiring of the inverters was partly dictated by my desire to have everything passing through the Immersun export CT, in the case of the extra panels this inverter tags on to the 'end of the line' and goes the long way around to get to the Main CU. I may take the export from the SB3600TL-21 the 'short' route to the incoming main CU. If I get the time I'll draw a rough picture and post it.

May post photo's later.

I took a set of figures from the export meters and DNO meter today to compare with a set I took on March 19th last year. My year on year import of energy from 1st January 2018 to 1st January 2019 was 8683kWh. The figure from 19th March 2018 to 20th March 2019 has dropped to 8045kWh. Overall consumption i.e. import plus use of units generated on site went from 11831kWh to 11521kWh over the same periods.

Richard, maybe I am not fully understanding your explanation, but,

You need ALL your generation from ALL your inverters to go throught the secondary SMA Energy Meter (entering from the top end exiting from the bottom), then that should go to your SMA Home Manager 2, entering the top end exiting the bottom and then that goes to the incoming grid.

nowty,

We may need to take this 'offline'.

The SHM 2.0 will obviously see the total PV generated and exported already (via Sunny Portal). The only thing the system (Sunny Portal) 'knows' is that the SB3000TL-21 is connected as it is on the Speedwire system. The source of the rest of the power being generated/ exported is, currently, unknown to Sunny Portal i.e. the ROO/ FIT and FIT PV systems.

When the SB 3600TL-21 is fitted Sunny Portal will be 'aware' of the FIT system and the 2.895kW of extra panels, but the ROO/ FIT part will be 'invisible'.

Sunny Portal will know the total export from the SHM 2.0 and will know the export of the two -21 inverters. It has no way of knowing where the other energy is coming from i.e. the ROO/ FIT 1.2kW system.

Thus my thinking of fitting the Energy Manager on the output of the ROO/ FIT inverter ('reverse wired' as you've already highlighted) means I can record the output of this system as accurately as the two -21 inverter systems.

Otherwise there is no real point of fitting it i.e. the Energy Meter, as the SHM 2.0 is already telling me the total export and the only source of this must be the Solar PV??

Regards
