> Ive installed a Multiplus ii 12 3000 230v with a Cerbo GX and Lynx smart BMS plus udated to latest firmware (Cerbo v3.42, Lynx Smart BMS v 1.11 and Multiplus ii v552) connected with Victron RJ45 cables, but I can see the BMS is not connecting to the Multiplus.I get the flashing bulk in contra phase to the ‘Inverter on’ flashing plus a constant absorption light on the Multiplus and a #15 error from the Cerbo. Anyone any thoughts?

Heb je een usb mk3 dongle?
