¿Alguien ha instalado este Módulo Goodwe en algún Inversor de la Serie ES, que reemplaza al Módulo WIFI y quiere compartir su opinión y experiencia?

Creo que es genial para aquellos de nosotros que estamos interesados en tener un monitoreo continuo las 24 horas sin los riesgos de desconexiones debido a fluctuaciones en las señales WIFI.
 

Hi @BGb !
1.) I have noticed that with old or low power processors the error rate of UDP packets increases. Also, in the next revision, I am going to correct this and leave it as optional for the User in the "Parameters" tab.
2.) That's right. I would be very surprised if they matched exactly. kWh is an integration of the samples over time. I do this integration with the samples second by second. I don't know how often the SEMS Portal does them. But we already know that the transmission of the data to the sems portal from the power inverter is never done at this sample rate of 1 second or less. Likewise, I don't think that for the calculations they consider the conversion efficiency of PV Energy to Alternating Current, so if you put 100% in the Parameters tab instead of putting 97%, the calculated Power will simply be the product A x V. You will see in this case that it is a little closer to the value that the SEMS portal shows you. In future revisions I will incorporate the "Auto Use" of the PV Energy to separate: Battery Charge + Essential and Non-Essential Loads from the Energy Exported graphically in the "GR" Tab
3.) I don't think so. Obviously if your PC is not running 24 hours, it will effectively have blank Accumulated Data during the time it is off since the Program must be running (i.e. it does not download missing data from SEMS or get any accumulated data that the Power Inverter could save to its own memory if it does so at this time). On the other hand, don't forget that the Totalizers in this software are closed Every Hour. Although graphically you can see the results in minute of hour in the "GR" tab.
In case the program is running and there is an interruption in the information it receives, either due to failure of the WIFI antenna of the power inverter or due to problems in your LAN, the current version will indicate the instant of the interruption or " Information frozen" and the re-establishment of communication. You can check it in the "EL" tab or errors/events.
4.) Sure! I can contemplate it in following revisions. For now you have the data in a .csv file almost second by second of several days and they are grouped by Minute, Hour, day, Month and Years only in a Graphical way.
5.) See answer 3.), however, in some future version I hope to be able to read the information from the Sems Portal to complete the data that is eventually missing with "hourly resolution" for cases of PC failure, Operating System or eventual freezing of the system itself software system.
Warning Number: 8
If you look at the current version of PV Master, you will find this same Warning in its Alarm Log.
I also have Pylontechs US3000C and from time to time this warning appears, which then clears up, returning to Normal condition after a few minutes. It appears when the batteries are charged to 100% of their SOC. I wouldn't worry if it disappeared after a few moments.

Hello. It looks like a very interesting and complete program. I have downloaded it, I hope to have the Key soon.

I present this program that I share with you in its VERSION 2.0. It is only for Goodwe Series "ES", that is, for GW3648D-ES and GW5048D-ES.

It has been developed solely for academic and hobby purposes, without any commercial objective.
With reference to Version 1.0 of the download area of the forum, beyond the correction of errors, small aesthetic changes, elimination of erroneous information from Goodwe itself (e_day and e_total), the self-discovery of the Power Inverter within the LAN network and adding battery self-defining parameters, I found it interesting to focus on one of Goodwe's weak points, which is the error log.

Like most users who have experienced them and beyond the degree of technical knowledge, I would have liked Goodwe some more information when a "trip" occurs due to different circumstances during the use of batteries, normal operation or provoked with reference to The Working Load and Maximum Powers allowed, either in essential or non-essential loads or in both.

The operating parameters in the event of an error, the SEMS PORTAL shows them with 1 (minute) between data, a true eternity, this is of little use and the resulting query is frustrating, generally.

Trip events ARE NOT REGISTERED by GOODWE, at least not in all circumstances from what I have seen.
Goodwe records some events that are of some use, but there are not many. These can be consulted in the PV Master application as you already know and with a descriptive text. In this system that I make available to the PowerPhorum community, the option * Error / event log * shows the GOODWE events registered in PV Master, whose code I have been able to associate with a description in red letters on a white background and with the In order for this to have a greater sense and utility, I have added to this register the fundamental parameters of Operation at the time of the Device Error, such as Temperature, Apparent Power (workload), Effective, Voltages, Loads, Batteries, etc.
The rest of the Events appear with the name "System", of these there is a group in black letters and a red background that are the Reset and Trip events, because when Goodwe is reset it does not leave any record. To partially solve this, the parameters that I show in these cases are the live values taken "1 (one) sample before the event", that is, if the update of the live data you want to set it to, for example, 1000 milliseconds and The this system finds that Goodwe rebooted at 10:25:30, for example, in the Event Log you will see the live data logged up to 10:25:29.
To be more accurate than what the Goodwe readings give, if you have higher precision instruments than the device sensors, for example with external AC meters like the Eastron SDM series,Carlo Gavazzi, etc., or for batteries using a multimeter or with a Victron BMB600 or BMV702 connected between the batteries and the Inverter, in the OPTION "PARAMETERS" the AC Voltage values can be corrected and, on the other hand, Current or DC Voltages in the state of charge or discharge of the batteries in +/- to the hundredth of a volt or ampere. In this case, in the "LIVE DATA" section of the left panel, the parameter with the [c] indication will appear. If you accept the direct Goodwe values without any correction, just leave the values at "0", I have also added the Goodwe "Self-Consumption" Value for better precision in energy calculations. My device draws between 60 and 66 watts, which is more than the manufacturer reports. You can adjust other values for greater precision that are self-explanatory.
They will also have an idea of the actual maximum daily PV voltages and amps under load conditions (V imp and A imp) of each string, which can guide us to make modifications to our strings by pushing a little further towards the Goodwe limit in a more safe.
The maximum daily values of some parameters appear on the main screen of the scheme. I emphasize that to update a maximum value, internally I consider it only if 2 (two) consecutive samples are higher than the previous one, this in order to avoid peaks due to AC harmonics and / or other electrical disturbances with very instantaneous peaks.
