Good Afternoon All,

That's me changing electricity suppliers again. Just shifted to Economy Energy (from Bulb) to save some £135 a year.

Good Morning All,

As a part of trying to get the Growatt working 'properly' I've been looking at my electricity consumption and trying to determine which device is giving me an 'accurate' indication.

I need to get back to SISEM as their suggested method of a 'hard reset' didn't work and they seem reluctant to have me start the unit too often! Their CT sensor over by the incoming meter is definitely 'out'. The Immersun has been set to only export 50W as the Growatt CT shows this to equate to circa 350W according to its CT sensor and I'm pretty confident of the Growatt sensor accuracy.

To keep this posting on track I'm sat here looking at the minim+ display and its telling me that my heat pump is using 400W. No problem you might say but it is supposed to be 'switched off'. The domestic CH function is off so the heating circulating pump is off, the ground loop circulating pump is off etc.etc. It isn't the Solar ET operation as there is no difference in indication when it starts up i.e. the minim+ shows 400W at 2300. This is costing me £1.46 a day if true.

I've sent an EM to CTC's Technical Manager to see if he can advise.

Does anybody on here have any observations or thoughts.

Regards

Richard

I personally wouldn't trust the Growatt. Certainly I find the online data recording and the app have loads of bugs in them.

Last night I was looking at the display of export on the Growatt and what my sunny boy was showing and there was probably at least a 30% difference. I can't remember the figures exactly but it was notable.

Tinbum,

I'm aware I'm dealing with something less then precision laboratory measuring equipment.

My baseline is that both Growatt CT's and the minim+ are aligned within 30W of one another which suggests a degree of accuracy and consistency.

I've just gone and dug out my Sealey MM405 clamp meter. It is showing 1.5A which at 245V gives me 367.5W which aligns well with the minim+ at 400W

The device that appears to be mis-aligned is the Immersun CT sensor.

Regards

Richard

Good Afternoon All,

Phoned the heat pump installers yesterday afternoon in a mildly irritated mood that the Solar ET system 'air' issue still hasn't been attended to. It is work in progress.

Whilst I'll defend the 'benefits' of Solar ET I'm still wrestling with what to do about exported energy when it happens. Yesterday I saw 6.8kW exported and a week ago it was 6.7kW in one day but these figures aren't consistent. It's an average of around 3.3kW a day over the last 15 days for instance.

I'd like to charge the Zoe with this but I'm struggling to see how I can make this happen with the charge point I have installed.

I could limit the amount of energy from the Solar PV that goes to the EHS and allow the Solar ET to do more heating of said EHS but I need this system to be working 100% first. This would help alleviate the issue of excess heat developed by the Solar ET system so could be a win/ win situation.

Thoughts welcome as ever.

Regards

Richard

Good Morning All,

According to the Immersun we managed to generate a total of 28.7kW of electrickery yesterday (this includes the Growatt) so a new daily production record figure for the property.

We also managed to export 22.2kW of it as there is nobody there............... Monitoring from afar we were exporting at a rate of 4kW at one point yesterday afternoon.

Still waiting on the Solar ET being sorted - no response to yesterday's EM - should be back onshore later today so if no response might have to take the Zoe on a trip down to Aboyne and speak to the firm directly.

Need to find an economic way of 'capturing' some of that 22.2kW.................. A Zappi is one answer but whilst 'free' charging exists it makes no immediate economic sense.

Regards

Good Evening,

Finally a technician will be around tomorrow to attend to the Solar ET issue. Hopefully the fitting of a Spirovent will allow the air to be properly vented from the system and for the first time since December 2016 the system may actually be air free and function properly.

Regards

Good Evening All,

Well the Spirovent has been fitted. As you can see from the picture:-

1. the outlet pipe and the vent are unlagged
2. the vent itself isn't at the absolute highest point as the return line can be see behind the vent and slightly higher,
3. not clear from this photo are the fact that there is a short length of exposed ribbed piping on the return line which is unlagged.

Hopefully the device will eliminate the air which again, despite another flushing yesterday, was still present this morning when the system flashed up. Hopefully the vent will function as required and the air will 'disappear' over the next few operations.

The installers reply to my EM this morning does not convince me they will attend to the lack of lagging - I need to be mindful as I know there will be 'tradesman' on this forum but work like this does the trade no favours at all and suggests that even when working for a renewables firm not everybody 'gets it'Huh?. I don't know but I'd be interested to hear others views.

Regards

Richard

When installing mine the instructions were specific that the vent HAD to be fitted at the highest point.

What you mean like these instructions from Spirotech?

They certainly don't take any pride in their work for sure. I have no faith in so called professionals who have a piece of paper that enables them to do the work.

Morning Richard,
Not identical but similar, as the water exited the frame holding the tubes, I ran the exit pipe and fitted the valve there just before it began it's descent to the tank so it was at the highest point. This was as it was shown in the manual, (more a series of photocopied sketches than a manual). Apart from a top up once or twice a year it ran for 8 years with no other maintenance.
I installed separate circuits in the kitchen to enable me to use hot water for washing machine and dishwasher, which with the benefits of hindsight was a bit of a waste of time. With only two of us in the house I looked to install an instant water heater rather than use the imersion in mid winter for the shower but the way france charges for the supply of electricity would have made this prohibitivly expensive. Hence you never see electric showers on sale there.

Good luck with yours

Tod

Tinbum,

In fairness to the installers this guidance only uses the word 'preferably'..............

The other link gives a clear pictorial indication with a tick and cross indication but even that isn't a 'MUST'.

There is no pressure in the system at all this morning and in the limited sun we had before Hector hit us there was still plenty of aeration to be heard.

Regards

Pretty sure Iíve seen installers with a bin full of glycol and a shower pump connected to the system to remove the air, they never add auto vents.
