How did you connect your Zeversolar inverter to the network? #1

Hey,

I have a Zeversolar inverter, ZL 2000S, and just recently stumbled upon your script that can communicate with - and more importantly - extract data from such an inverter.

I have, however, been unable to figure out how to connect it to my network. I have opened the box and found two Ethernet connectors on the inverter PCB, but when connecting either to my network, the inverter does not get an IP, neither does it light up the LEDs of the network switch in the other end of the cable. I did succesfully test my laptop through the same Ethernet cable, just to confirm that the cable works.

I do understand that there's a ComBox module that unfortunately my Inverter does not have.

So my question to you is; Do you have your inverter connected through the ComBox or the internal Ethernet connectors? Do you have any images of the inside of the inverter where the Ethernet cable is visibly connected?

I hope you'll reply to my message.

Thanks, Kenneth

Hi Kenneth, I also have a Zeverlution 2000S - but mine is about 8 years old. If a have read correclty, it should be possible for you to get the inverter data. Just for information: here (https://www.zeversolar.com/fileadmin/user_upload/pdf/usermanuals_en/installation_and_operating_instructions_zeverlution_1000S-3000S_en.pdf) is an installation and user manual. Your inverter should have an internal ComBox module (the internal PCB having two RJ45 connectors and perhaps a RS485). And here the misery starts. Either the description is misleading or the module is country-specific. If I had read correctly, you have to use the right RJ45 connector (ETH) and not the shown DRED port). I didn't have that problem because the electricians ruined my CAT-6 cable so i had to switch over to WLAN. After mounting the provided WLAN antenna (without i had to put the router aside) it worked fine. After switching through the menu (10th? position) I found the IP-Address. It was pretty strange (169.254.x.x) and out of my network range, so I had to change my TCP/IP configuration of my PC to get connected to the inverter to change its network settings.

Thanks for the quick reply!

I don't have the option for WLAN, so I would suppose that you do have the ComBox module installed in your inverter.

As I said, I did already try out the two different ethernet ports inside the inverter, however the IP shown in the menu keeps being stuck on 0.0.0.0 regardless.

I must conclude that in order to succesfully get my inverter connected to my network I would need to get hold of a ComBox module. That might be a bit difficult, given the company went out of commission in 2019. So I guess this is a premature end on my data-extracting journey.

Thanks, Kenneth
