October 13, 20241 yr What is the solution to the inverter interference on the Internet? From 7 AM until 6 PM, there is strong interference on the Internet. The SNR becomes 20. At 7 AM, the SNR becomes 6 and the Internet is very slow. Knowing that I changed the filter and moved the router away from the Inverter, it did not help. What is the solution?
October 13, 20241 yr What Internet is it, fibre, LTE etc? Are you running your lan cables close the power cables?

It also looks like your MPPT's are causing interference when the sun is up and generating power. What inverter do you have, and anything strange with the way the panels are connected?

October 14, 20241 yr Author We in Syria are still using adsl. When the panels work immediately, snr, I have 20 and it becomes 6, and the internet disconnects. I extended a special cable to the router far from the power source, and nothing benefited. I also changed the router. For your information, the panels are directly above the roof of my room. 4 panels. In the evening, the internet starts working properly, and snr 20

Edited October 14, 20241 yr by HendrikBigChief
October 14, 20241 yr That sounds like interference from the Solar Panel feed cables and/or the Inverter. Only recommendation I have is that you see if you can get enough ferrite beads for your ADSL line and it's power supply cable.

To eliminate the electromagnetic interference (EMI) caused after installing an inverter, the following steps can be taken: 1. Add shielding to key components of the inverter and ensure proper grounding of all metal enclosures, wires, and shielding. This helps reduce electromagnetic radiation. 2. Install electromagnetic interference filters (EMI filters) on the input and output lines to suppress high-frequency noise. Common filters include LC filters and EMC filters. 3. Twist power and signal cables to minimize the electromagnetic interference radiation and reduce the coupling between wires.
October 15, 20241 yr Could it be related to the latest extreme solar storm? The earth has received massive radiation levels during the last days.
