Cef Posted November 12, 2020 Share Posted November 12, 2020 (edited) Hi. I am designing a system that works on windows from Xp to 10, which reads the Data sent by the Goodwe "ES" to the LAN Network, in the same way that the PV master or EzManager applications read them, I put a Youtube Link of the system in deal: https://youtu.be/S2CSYPYRD-Q At the moment I am doing the Error Reference Log and cannot find technical information on all possible errors. I only have information on 3 of them, namely: err = 537002496 = "VAC FAILURE E23" err = 536870912 = "FAC FAILURE E03" err = 537001984 = "VAC FAILURE E15" The 1st Number is the one that the power inverter gives to the PV Master and that is the Reference I need for the Rest of the possible errors, for example for: - SPI failure or an internal communication failure - EEPROM R / W failure or memory chip failure - Relay check failure or a relay self-checking failure - Overhigh DC injection - Isolation failure - EFan fault - PV over voltage - Over temperature - DC Bus High - Ground I Failure - Ref 1.5V failure - AC HCT failure - GFCI failure Others - Device failure Someone who can give me some more info about it? Thank you ! Edited November 12, 2020 by Cef Quote Link to comment Share on other sites More sharing options...

By signing confidentiality agreements with Goodwe this information could be available in a very short time, but could not share or publish it. The routine is already created in the system and any new error is recorded with its number. From there it is easier to find the information since the PV master in the ALARMS option provides some information about it or it may be found on the Internet.It is a pity that there are not more interested in teamwork, with this we would all benefit. Likewise, in other aspects the System is progressing very well, with respect to the Initial version that is in the Downloads area of the Forum in addition to the LOG, it is no longer necessary to know the IP address of the inverter in the LAN network, it finds it automatically and it connects with the inverter on its own and some other cool stuff. Now I am focused on other aspects, for example I discovered 2 more interrogation commands that are not published in the original posts that launch the EzManage and the PV Master to the inverter on a regular basis. I'm doing a smart routine so I can decode the response information and make sense of it. As soon as I have more information about it, I'll publish it.

PilgrimToHyperion Posted January 16, 2021 Share Posted January 16, 2021 Just wanted to say thanks for this, Cef. V1.0 works great! Some text are cut off, but besides that great! Quote Link to comment Share on other sites More sharing options...
pspspeed Posted January 17, 2021 Share Posted January 17, 2021 This is great - thanks - don't have to use SEMS for live data. Quote Link to comment Share on other sites More sharing options...
DanieT Posted January 17, 2021 Share Posted January 17, 2021 I have a setup that was suggested by an installer what I call totally incompetent. That's a Goodwe ES with two Blue Nova 5.2Kwh batteries. The sad part is there is no communication between the inverter and batteries at all. I now rely on the Blue Nova BMS. SEMS is not working as my plant is registerred on his profile and is offline. Not much help from Goodwe and no other installer want to thouch this combination. Quote Link to comment Share on other sites More sharing options...

DanieT Posted January 19, 2021 Share Posted January 19, 2021 Cef, What communication route are you using to connect to the Goodwe, via PV Master or SEMS? Is it possible to connect wired? My reason for asking is the unreliable WiFi that stop working whenever the system resets. Quote Link to comment Share on other sites More sharing options...
Cef Posted January 19, 2021 Author Share Posted January 19, 2021 Hi @DanieT, if you mean the system I made, it communicates through the UDP / IP protocol. It is the same as the PV Master and the EzManager, in a Local Area Network, however you will see that the communication will be much more solid than that of the PV master. Unfortunately, Goodwe doesn't have an Ethernet port for a wired outlet. It is not necessary to have Internet access to observe your data in real time that is updated in the time interval that you select in the program. Depending on the stability of your network, the errors will be higher the lower the set polling interval. It all depends on how close your router is to Goodwe. Try to adjust this time so that the ratio of packets with CRC error and packets received without error is no more than 2%. The best solution with this bad connection way to do real-time monitoring (WI FI) is if you can't get your router closer is to buy a WIFI network extender On the other hand, the SEMS data is updated approximately every 5 minutes. In a later version I will add the connection function of this program with the SEMS API and be able to access historical data without entering its WEB page through a browser and thus have the information simultaneously with what is obtained in real time.

DanieT Posted January 19, 2021 Share Posted January 19, 2021 Cef, Thanks for the quick reply. I have a router 5 meters away. Signal is 6 to 10 Mbps at the inverter. I can't log onto SEMS as the first installer removed my name from his guestlist. David Hvenga from Goodwe said my plant is visible on the cloud but my system show offline. Is there a way to reset the system to remove my plant from the original installes profile? The only option to set the BMS is self define for the Blue Nova batteries.

Sorry, this can only be done by the goodwe representative in your area or other personnel authorized by Goodwe. Your best option for what you count is to make a Request Ticket to: https://support.goodwe.com/portal/en/newticket Quote Link to comment Share on other sites More sharing options...
abrax Posted March 21, 2023 Share Posted March 21, 2023 On 27/11/2020 at 01:44, Cef said: CIAO@DanieT. Ho ricevuto solo informazioni su un nuovo Errore: 512. Firmando accordi di riservatezza con Goodwe queste informazioni potrebbero essere disponibili in brevissimo tempo, ma non potrebbero condividerle o pubblicarle. La routine è già creata nel sistema e ogni nuovo errore viene registrato con il suo numero. Da lì è più facile trovare le informazioni poiché il master FV nell'opzione ALARMS fornisce alcune informazioni al riguardo o può essere trovato su Internet. Peccato che non ci siano più interessati al lavoro di squadra, con questo ne trarremmo tutti vantaggio. Allo stesso modo, in altri aspetti il Sistema sta procedendo molto bene, rispetto alla versione Iniziale che si trova nell'area Download del Forum oltre al LOG, non è più necessario conoscere l'indirizzo IP dell'inverter nella rete LAN , lo trova automaticamente e si connette con l'inverter da solo e altre cose interessanti. Ora sono concentrato su altri aspetti, ad esempio ho scoperto altri 2 comandi di interrogazione non pubblicati nei post originali che lanciano regolarmente EzManage e PV Master sull'inverter. Sto facendo una routine intelligente in modo da poter decodificare le informazioni di risposta e dargli un senso. Non appena avrò maggiori informazioni in merito, le pubblicherò. every now and then i get code 512 , i don't understand what it is . just yesterday when the electricity went out it gave me this error 512 and then code 0 Quote Link to comment Share on other sites More sharing options...

This is an old post. At that time I was learning about this subject. In Version 4.xx all the errors of Goodwe and the explanation of it appear. They are the same ones that appear in the PV master record. Edited March 22, 2023 by Cef Quote Link to comment Share on other sites More sharing options...
