Hi everybody! I have a problem and I really need help. I have bought 3 2nd hand inverters Phoenix Multiplus 24 3000 70 and I'm trying to configure them in parallel but I'm not able to connect. All downloaded softwares are connecting to MK2-USB adapter but cannot detect the device. The firmware version is: 1812143. I also tried to configure them using the DIP switches following the instructions of the manual but unsuccessfully. Please help, I'm in Africa and I cannot contact anybody
