Hello Good People
Does anyone have any idea when this http://www.eco-eye.com/products-smartPV.html is coming?

Does anyone consider there is an alternative at this proposed price

This looks very interesting. I think there will probably be quite a few similar devices launching shortly for us Inverter Addicts!

Still only seems to use clamps with no ac voltage signal to obtain the power factor and current flow direction so I guess accuracy will be no better than 80%

PV+Thermal. It all looks a bit random, but isn't.

Beware. I bought a single clamp meter device for the input and find it is confused by the presence of the inverter. It implies the inverter consumes power at night which is refuted by measuring the consumption meter. I think meters using sensors counting flashes from the accredited meter will be much more accurate. Undecided

According to the manual that came with my inverter my inverter uses < 2 W 'internal consumption during nighttime'!

I agree with Paul above. Mine is ordinary Eco-Eye with follg results-

1. Clamped on the 'usage' cable, it shows sensible rises from zero up, while switching on succession of 20watt bulbs.  Smiley

2. Clamped on net import/export cable, it  would not go anywhere near zero when I tried to balance usage with generation. banghead

Fortunately , the flashing Generation meter did agree with the Sunnyboy which restored my beleif in Sunnyboy Smiley

60 watts on Sunnyboy; when flashes were about 1 per min ( ie 60 per hour ie 60 watts).

I'll add that I think there must be a noticeable phase difference, so it was impossible to get  near zero when I was  trying to balance  usage with generation power.

And you cannot tell whether the value is import or export.
 
In summer, with much bigger values, it should work better Smiley

I have a Wattson energy monitor which implies my Power one inverter  / soladin /windmaster 500/ collection of OK4e micro inverters use a total of 97 watts continuously at night. I do not believe they do  !!!!!!!
Problem is it deducts this 97w from my usage as it believes it's a generated figure so my usage in the evening looks good. Roll on an easy to install device that counts meter flashes - the only honest way of measuring consumption and usage.

OK being a bit of  novice to all this - are we concluding that the suject 'eco eye pv smart monitor' is no use and serves no useful purpose???

Well I do like my EcoEye when the sun rises and the generation increases by hundreds. Smiley
The big display is easy to see, as you walk around the room. Or carry it about.

I have to remember that  can't add or subtract properly for values below 100 watts.
It doesnt know the phase factor which seems to make bigger errors there; Maybe other sources of error like electronic noise.

The Brultech system from Canada and TED for the USA seem to be the only products that can display accurate data (and know the power factor and which way the current is flowing).

Brultech however seems to need a PC on all the time to save the data which is output up to every second (available in UK but have to order from Canada).

TED should be better as it has nice display units so I don't think a PC needs to be on all the time (UK model however several months overdue).

Other snag is both system cost three figures.

Hi Everyone,
I am Peter Longley, Technical Manager at Ecp-eye.
I have had a quick read through and thought  I could give you some answers.
SmartPV will be on sale 16/1/2012 and will be 86.40 including VAT.
For that you will get:
Transmitter,
2 current sensors
1 peak voltage detector
Smart display
Memory card (recording at 4 second intervals)
USB cable for real-time output, firmware upgrades etc.
Trax - computer program for Smart - at the moment only Microsoft Windows but Linux and Mac will follow soon.

The two current sensors clip round the neutral on the PV and the neutral under the main meter. the peak voltage sensor is wrapped around a live cable. Plug all this lot in and you will get a readout of generated, used or nett together with a flashing green (surplus), red (using from grid) or yellow if the two are about the same.
The peak voltage sensor allows us to deal with the problem of inverters going out of phase at low inputs and improves the accuracy greatly
.
We intend to keep developing both Smart firmware and Trax as users tell us what they want. There is a wifi module coming soon and around Easter there will be appliance modules that can be controlled by Smart.

Hope that helps  - any questions, just ask.

Good luck
Peter

I'm not technically minded but this looks like what I would like ... this will show what I'm generating and what I'm importing... when to put the dishwasher/washing machine on, or more importantly when not to put high load things on .. I use an average 10 Kw a day so any help would be good.

 
Could the monitor be away from the meter by about 30ft ?  is it blue tooth?


I have generated 144 kw since my install on the 11/11/2011  I'm a happy bunny we are not south facing and the sun has gone to the side of the house just after midday  Sad but spring will be better extrahappy .. roof is about 40 deg  .. 16 Sharp 245 panels

16 Sharp Mono 245 panels should have been 250's... Sunny boy 3800 should have been 4000TL but they will come back and change it to the 4000TL

The SmartPV transmitter and display are linked by 433Mhz radio - so 30 feet should be no problem.

I have the eversolar solareye.The solar bee (transmitter) just goes in the ethernet port of the inverter and wirelessly transmits the data to the eye,seems good to this novice but it wont stay displaying data for more than a few minutes until i press a button which is a bit annoying for a pv watcher!
