I use one of these https://www.aliexpress.com/item/1 for my ICC and internet router and i dont have any problems now!

Why not attach a multiplug that is attach to your inverter and use your inverter as a Big ups

always try and use a EL when you connect any plugs to the inverter you get cheap 25amp and 15amp EL units with double issolation, Accidents happen so easy, and 5kva will teach you a lesson that you may not want to learn.

By assumption, I believe your Pi should be fairly close to the inverter No?

Then why not rather use a simple DC-DC or el cheapo Buck to power the Pi?

Or am I missing the point here?

REXX?  ... is a scripting language available for many OSs, also for Linux and Raspian. I tried to modify the autostart script that come with aicc.  Yes, i tried!  with no success. So i searched and installed REXX.

This is now my ICC start script:

#!/usr/bin/rexx
trace 'o'
/* started by autorun: in pi/.config/lxsession/LSDE-pi/autostart */

dir = '/home/pi/AICC'
log = dir'/RunAICC.log'
start_time = time('E')  /* start stop watch */
logt = 'ICC started at' date() time()
call lineout log, logt  /* write to log */
say logt

rc=chdir(dir)  /*go to aicc directory and start aicc*/
address cmd './ICC'   /* start app */

/* calc run duration hrs min */
duration = time(R)   /* read stop watch */
hours = duration%3600  /* get hrs only */
minutes = (duration//3600) % 60  /* from rest calc mins */
logt = 'ICC ended at' date() time() '- duration:' hours'hrs' minutes'min'
say logt /* say to console */
call lineout log, logt
call lineout log, '- - - - - - -'

Log file sample:

ICC started at 14 Feb 2017 18:42:01
ICC ended at 14 Feb 2017 18:42:01 - duration: 15hrs 51min

Isn't it nice and easy to read?  Rexx is typeless, all conversions are done at the time its needed - Automatically.  

---------------- 

So far - so good.  I tried to autostart this script by adding it to pi/.config/lxsession/LSDE-pi/autostart.  That did not work. Is there no tool/gui that helps to configure autostart of programs?  There also must be a list of programs that already start automatically.. 

@Manie and all other interested members, I would suggest that we start a thread "ICC improvement suggestions" so that all clever ideas, we are all smart people, are we not, can be consolidated in one place. This forum is becoming like a haystack and it is difficult to find things one has read before at a later time.

That said I will once more contradict my own suggestion. I find that my load is jumping around a lot. This morning on my tablet, while still reclining in bed, yes we retirees don't have to fly out before the sun rises, I observed loads from 362W to 629W over a few seconds. Equipment drawing power was a PC and related network stuff, 4 x CCTV cameras, fridge and deep freeze as well TV and DSTV decoders on standby mode. Perhaps a moving average or weighted moving average display will give one a more realistic view of the load. Depending on how often the values are read, a suitable ring buffer will do the trick. If values are read every second, then a 5 element buffer array should suffice and result in a smoother graph. It should not be a great deal of programming and when you have time, something I guess you don't have in abundance Manie, you might like to give it a thought.

Hi @ebrsa The release that i am testing now would be the final release for version one, as it seems stable and doing 90 hours without an err. I will see how the sales progress as it should alo be beneficially to me , I spend a lot of hours on the Pi project and help a lot of hours users (a lot of hours) At the end it looks like it's  not  beneficially for an average of R500 for the pi app. The user get a trail in the beginning and some not all keep me busy the whole day setting up thing. Then a lot of questions what is emon en PVOutput and how to use it as so forth.

The pi project is not finish as there is a lot that i want to add for myself and if all goes well , version 2 will start. If users want it. There will be an upgrade fee. I can't continue  adding and adding and don't reap the benefit and waist my time. I have to pay for controls and also for hosting the website. There is still a lot to do there.

The same will happen to MQTT we add more stuff there. It will cost an upgrade fee as well.

Regards

 

1-On "Inverter Value" the values for PV2 are always 0 (zero). Although on cluster the info page both inverters have watts and volts.

2-Sometimes PV Watts have a value of 100'000 !!  This may be a HW bug - but couldn't it be filter out?

Please read the thread. Does your inverter have 2 mppt charge controllers?
If not there will be no pv 2. I have adress the issue before.

In the new version the naming has change to Mppt 1 and 2

If you give me a idee to filter it out then yes we can try to do that. Howmuch can your panels read at peak time? Do we filter it out by 5% more than your panels.
10 % ?

This hapens onece in a while maybe 1 time every 6 months. If you look at it , it is just before sunrise or sometimes with change to solar/grid

I have two Axperts 5kW, both each one has panels connected. I think both have MPPT integrated. The one running as slave is newer and another make/model than the master inverter.  

Can't i find out?

 

 

 

Each inverter only have one mppt for the Axperts.

 

You have to look at your manual.

Instead of filtering: Limit the y-axis of the graph or make it logarithmic. No?

So in this case, @PeterGutti you will need to run 2 copies of ICC, one connected to the master and the other connected to the slave. 

@PurePower the master inverter does not have USB! And btw. i think the figures a get in emoncms are correct, its just that two values in the GUI are zero.

It's always shortly before sunrise?  That's interesting.  Static charge?

Not sure. My Axpert did it once or twice. However not with the Infini. Aslo different price class

I does not matter if your master does not have a USB. As long the inverters are running in parallel and the slave has a USB, it is fine. The data for both inverters will come through. You can connect any inverter, master or slave to retrieve the data.

Yes, it will always be zero. Although you have 2 inverters they only have a single MPPT, not a dual like some other inverters. If you watch PV1 Watts and PV1 Volts closely, you will see the data value changes about once a second. It is displaying Inverter 1 and then Inverter 2 Watts and Volts in a continuous loop, all in the same PV1 block. 

If you read the first and second post in this thread, you will see that in this new version 1.1.3, those data values will now be available separately in the cluster and in Emoncms.

I saw those spikes quite often gave me a hell of a scare in the beginning but it was always the solar feed .. the BMV never recorded a spike in the charge so I knew it was dud data 

I think it happens when guys get frustrated with clouds moving in front of the sun and bangs the inverter with the head. 

@Manie jou voorstel dat v1.1.3 die laaste uitgawe vir die huidige een is redelik en aanvaarbaar. So ook die voorstel dat opgradering 'n fooi sal behels en hoeveel dit moet wees is vir jou om te besluit. Eintlik moet die prys so hoog as moontlik wees sonder om kliente te verloor. Kompetisie is ook 'n faktor as jy mededingers het wie se produkte vergelykbaar is. Daar is geen punt om te vergelyk as jou produk in BMW of Mercedes klas val en die kompetisie in een van die Chinese of Indiese klein motorgroepe nie. Dan is hulle heeltemal uit jou klas.

Ek is besonder bly om te hoor dat jy graag wil voortgaan met ontwikkeling en sal voorstelle wat moontlik tot die produk se kwaliteit en fasiliteite kan bydra en opgradering aanmoedig met graagte bydra want op oulaas is dit ook tot my voordeel.

Een voorstel ten opsige van "trial version". Skryf 'n stap vir stap instruksie om die "image" op 'n SD kaart te laai en klaar. As mense nie bereid is om dit vir die toetsweergawe te doen nie, is daar geen rede waarom jy ure lank daarmee moet sukkel om enkelinge te help nie. Ek verwys weereens na die ontwikkellaar van Blueiris CCTV program waar daar 'n "helpfile" in die program is en 'e-pos address en dit is dit. Ek het al oor 'n kamera navraag gedoen en die antwoord was "Gee my Teamviewer toegang ot julle stelsel en ek sal kyk wat gedoen kan word wanneer ek tyd het" Mettertyd het hy wel 'n antwoord verskaf maar dit het wag gekos.

 

 

 

 

@ebrsa Thanks , Yes i think it still nice to see what users want and what can be implemented in version 2. I really thought with the image already set up that it would help the user as it is just to burn the image and there you go.

I must agree with you that there should be a help file that can be attached to the program. I was just under presure with what happen with AICC and had to do a lot to get things going for the user, that i did not have any time to do a manual. Everyday after work , i worked on ICC till late at night and this is still going on since the first post for ICC. I did not even use one day and did something else. While i am typing now, i am busy with the windows one . I have to thank @Don, @Riaanh, @ebrsa , @cvzyl and @Czauto for helping with the test work. Sorry if I missed someone. I appreciate all users feedback to make this a nice solar app.

Jissie Manie, I think you're the one who need to get a thank you. The "testing" I had to do was to install the Windows ICC and run it. No problems whatsoever so far and yet you keep updating with new features......Thank YOU!

@Manie we are all in debt to you for all the outrageous hours you work to our collective benefit. I was just trying to point out that another sole developer of a program, after many years, has only the help file, which is comprehensive, but no manual. Also trial users really do not deserve any more than a basic set of instructions of how to program an SD card with the image. The manual or help file can come in time and there is only so much you can do in available hours. It also gives all of us the opportunity to become a bit more familiar with Linux and not bother you for downright undeserved answers to questions without taking some trouble in finding solutions ourselves. But mankind is arrogant and demanding. There comes a time when one has to say enough is enough and remember even though the program may perform like a Rolls Royce, there is a somewhat significant difference in price. Maybe some day when time allows, if ever, you could offer unlimited help but at the price of a Roller or an annual fee for X number of hours. Let's see how many clients want that.

Unfortunately this is how the world works and one has now option but to put your foot down hard when things become unreasonable or impossible. All I can tell you, it works for me with all the community work I do in our town for free. Your ICC is essentially free for all it can do.
