Sunspec monitor van zonnepanelen

[joezzt]

Dag Allemaal, omdat ik niet tevreden was met de monitoring van Solaredge Inverters en ik een probleem had en heb met de installatie, zie hier , heb ik een programmaatje gemaakt om mbv Modbus TCP de realtime power data en nog meer van een Inverter uit te lezen, in mijn geval de SE15K.
De solaredge portal heeft als vervelende eigenschap dat de resolutie in tijd is beperkt tot 5 min of 15 min voor veel dingen. Daarnaast geeft ie de instantaneous power weer, dus een gesampelde power, en energie in 15 min.

PVOutput gebruikt ook de instantaneous power van de solaredge portal, die wel per 5 min beschikbaar is, maar deze is dus gesampled, niet een max, min of avg. De energie wordt zelfs van deze waarde berekend, niet erg betrouwbaar. Als je bij PVOutput aangeeft de Energie van de inverter te willen gebruiken wordt deze maar elke 15 min weergegeven.

Al met al, niet erg nuttig allemaal voor fouten analyse, je wil toch wel op z'n minst een min,max en gemiddelde weten van die 5 min !

Entree, de Sunspec monitor, deze leest via Modbus TCP elke seconde de waardes waarin ik ge-interesseerd ben. Dit gaat parallel aan de normale solaredge monitoring , je hoeft er niks voor te laten, te solderen of aan te sluiten !
Elke 5 min worden verschillende waardes ge-upload naar PVOutput: Totale lifetime AC energy, Max power. Min power, Avg power en efficientie (gemeten van DC power naar AC Power). Die laatste is niet zo interessant, staat bijna continu op 98.5 %.

Zie hier een voorbeeld
Je ziet duidelijk bij een zonnige ochtend de Min power naar 0W gaan , een teken dat er iets niet klopt aan de installatie. En bij een bewolkte ochtend is er niets aan de hand

Het programma staat op Github:
https://github.com/Joozzt/Sunspec-solar-panels-monitor
Het is een QT programmaatje, dus heel makkelijk te porten naar Linux of macOS.
Een Windows Installer heb ik erbij gezet :
https://github.com/Joozzt.../SunspecMonitor_1.3.0.exe

Als bonus leest ie ook de Youless energiemeter uit en upload die naar PVOutput !

Om te gebruiken:
1. Bij Solaredge , Enable Modbus TCP
2. Installeer en start het programmaatje op een computer in je lokale netwerk.
3. Kies menu File/Options , geef bij Inverter IP:port het IP adres en poort nr van stap 1 , bv 192.168.178.10:502
4. Geef eventueel een Youless IP:port in , bv 192.168.178.23:80
5. Geef PVOutput System ID en API key in. Als je de PVOutput System ID leeg laat zal ie niets uploaden.
6. Naast uploaden worden alle gemeten waardes, per seconde, ook in een CSV file gelogd in de "Documents" folder.
7. Press "Start" , dan duurt het 25 seconden voordat er waardes geschreven worden in het venster, dit is de delay om de inverter waardes te synchroniseren met Youless.

Deze software zal ook te gebruiken zijn bij andere types inverters.

Voor mij is deze software nu genoeg, als iemand anders nog wil uitbreiden, ga je gang ! Is open source.

Cool!

Bestaat er een kans dat er nog een keer een Pi versie van komt?

[BizzieBis]

Leuk project! Lijkt me vooral leuk om een soort Live Dashboard van te maken. Met een aantal meters die de actuele standen weergeven.

@teacher Voor de PI bestaat een soortgelijk Perl script: sunspec-monitor

Er is ook een aangepaste versie voor Domoticz aanwezig in het volgende topic: https://www.domoticz.com/...cd79d71b&start=40#p173482

beste Allen,

Omdat ik in mijn zoektocht naar info ook langs dit draadje ben gekomen dacht ik dat het leuk zou zijn om wat info te delen.

Eigenlijk een beetje het zelfde als Joozzt, maar dan grafisch.
Ik heb een scripje gemaakt dat Sunspec uitleest op linux (pySunspec) en daarna in Grafana (influx DB) zet.
Met want hulp van mede tweakers heb ik dit voor elkaar.

zie grafiek hieronder, ik denk dat de metertjes zichzelf wel wijzen..
Als iemand intresse heeft in het script stuur ff berricht.





ps, in principe is dit toepasbaar op alle inverters die sunspec (modubs tcp) ondersteunen.

Ik heb Modbus TCP/IP in Node-red draaien en dan naar Influxdb en in Grafana

Is vergelijkbaar denk ik.

[joezzt]

@jawmoret kijk eens even of bij jou ook het ac vermogen precies (+- 0,02%), altijd, 98,5% van het dc vermogen is?
Of eventueel een ander maar constant percentage.
Zou zo maar kunnen dat solaredge het ac vermogen berekent van het dc vermogen en de in het lab bepaalde efficientie, al of niet constant....
Of andersom, dcp=acp/0.985

[ Voor 5% gewijzigd door joezzt op 30-07-2019 08:25 ]

[jawmoret]

@joozzt begrijp ik je goed, denk je dat het AC vermogen een berekende aarde is en geen zuivere meting?

ik heb van vanmorgen een paar punten genomen en de efficientie berekend, is best wel erg nauwkeurig op 98,5%....


DCP / ACP / %
595.8 / 586.9 / 98.50
631.8 / 622.3 / 98.49
733.9 / 722.9 / 98.50

[joezzt]

@jawmoret Inderdaad... Dit ziet er erg verdacht uit !
Kan toch niet zijn dat de efficientie constant 98.5% is. Zeker niet volgens hun eigen datasheets:
https://www.solaredge.com..._inverters_efficiency.pdf
Of de datasheets geven de gecombineerde optimizer/inverter efficiency ? Dan nog...
Kijk eens in de efficiency van mij vanochtend, extended data:
https://www.pvoutput.org/intraday.jsp?id=69932&sid=62143
Er zijn een paar overgangen, die kunnen corresponderen met afrondings-fouten in hun DSP's (16-bit ?).

Ik heb sinds kort ModbusTCP aan staan op mijn SolarEdge Inverter en ik ben bezig om in node-red e.e.a. op te bouwen en een dashboard op te zetten in combinatie met m'n Homey en MQTT.
Aangezien ik nog een enorme beginner ben met Node-red...zou je mij misschien je Node-red configuratie kunnen sturen?

Ik krijg het maar niet voor elkaar leesbare waardes tevoorschijn te toveren.
Ik loop volgens mij een beetje stuk op het omzetten van de register-waardes.

[AUijtdehaag]

@tmaniac Ik gebruik het niet meer via modbus tcp icm sma omvormer, maar maak gebruik van sbfspot en mqtt.
Probleem wat ik vaak heb is dat de modbus tcp/ip verbinding telkens onbereikbaar is, na aanpassingen in node red. Dat is software bug of ik doe iets gigantisch fout.
Wil @Tsurany misschien helpen?

Kan het zijn dat je met de connecties naar de omvormer in de knoop komt? Heb een soortgelijk iets gehad en zag (via netstat) dat node-red alle modbus connecties telkens opnieuw opzet. Zeker als je kort na elkaar 'published' zorgt dat voor problemen.

Nu ik daar rekening mee houd, draait het best stabiel hier (SMA SB4.0)

Zo, dat is een flinke flow

Ik heb (al dan niet een beetje omslachtig) een manier gevonden om er wat mee te kunnen doen;

Ik heb online een python script gevonden (sunspec-ardexa) die heel eenvoudig de inverter uit kan lezen en de data in een CSV file dumpt.

Hier heb ik een PowerShell script omheen gemaakt die ik vanaf 1 van m'n servers vanuit een scheduled task laat draaien.

Elke 30 seconden worden de waardes uitgelezen en in een CSV file gedumpt, deze wordt ingelezen en gepubliceerd in m'n MQTT broker.

Nu kan ik een dashboard maken in nodered en een device toevoegen in Homey.
Op deze manier heb ik toch nog the best of both worlds

(Python kan ik niet, NodeRed ben ik aan het leren maar PowerShell gebruik ik beroepsmatig dus daar ben ik wat meer in thuis, vandaar deze 'omslachtige' oplossing)

Topic bump, ik wil ook modus gaan gebruiken van mijn solaredge inverter. Maar ik kan het niet enable-en ? Iemand idee wat ik moet doen

[joezzt]

Weet ik niet meer uit mijn hoofd, ik heb nu een omvormer zonder display. Maar knopjes zijn er om op te duwen ;-) Dus probeer wat, bovenin staat een link naar SE manual.

Dat doe ik altijd graag, maar krijg het niet voor elkaar . Zie nergens een optie "enable"

[MaikelK.]

is het jullie al eens gelukt om data naar de omvomer te sturen?
Dit om niet ook nog een extra meter aan te schaffen om de echte import/export waarde te sturen?

Dus hetzelfde doen al wat de Wattnode of Inepro meter doet?

Ik zou deze monitoer graag gaan gebruiken, maar waar vind ik de API key? Niet te vinden op het display van mijn SE5K inverter. In de MySolarEdge app heb ik wel een system Id (decimaal) gevonden. Ik weet niet of dat de goede is. Op het display van de inverter staat ook een system Id, maar dat is in hex.

Graag een hint voor de API key (encryption key?). Met veel dank.

[Douwe Fokkema]

Ik heb de API key gevonden. Gewoon inloggen op je SolarEdge account, dan naar Admin, onderaan de pagina kan je een API key genereren.

Ik kom toevallig deze vraag vijf jaar later tegen. Ik liep tegen hetzelfde aan. Je moet het poortnummer de eerste keer bevestigen door OK ingedrukt te houden. Daarna is Modbus te enablen/disablen.
