Good morning , Is there anyone that can maybe guide me with a problem that I am experiencing. I have a Luxpower 3.6 inverter with a 24v/2.56 kw lithium battery. At this stage we do not have solar panels as yet .It is a basic backup system for our setup. Our small office network consist of a server and to this I have 6 pc's connected via Cat 5 Ethernet cabling. When the system work straight from the grid everything works 100 percent. If I plug the system into the inverter and we work from battery without a grid connection everything works 100 percent. When I connect to the mains grid my ethernet network go down. Unplug from the grid everything is working again. I have replaced the tplink switches with a Ruijie switch that is made out of metal and I connected it to earth. Baatery and inverter is also earthed. I do not know where to look anymore. I need details of a Luxpower technician that can guide me. I have spoken to the guys at Solar Europe and they provided me with a number for their go to technician Ayob but he does not answer his phone. Thank you
