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.

Is it possible to use it on a PC at work? How can I connect to my home network? I can't do it with a VPN tunnel. Do I need a new hex key on a PC at work? Thank you for your response. Regards

Hi everyone.

I wanted to show you a short video based on the answer to a question from one of the forum members in another thread.
It is not my intention that this thread becomes distorted when entering another topic. It is only to inform you that this program that is already used by several of those who read this thread, was fundamental for me specifically regarding the invention that I show you, to adjust and test in my installation the Circuit that you observe in the video board, with the Power Data in Real Time and the stored data. Daily maximum of Amp, Vmp and Efficiency of the 2 chains that share the PV2 input.
By the way, I take this opportunity to demonstrate that continuous monitoring 24 hours a day, 365 days a year is possible with Windows.
Regards !
