I have a multiplus 12/ 3000 150/50 230v. Color Control GX, 12.8v Lithium setup with ve.bus BMS
The unit is functioning flawlessly however we have just stopped at a marina where the shorepower is a little higher than the allowed tollerances of the multiplus and I need to go into to reprogram. The Lithium assistant is enabled.
The moment I unplug the ve.bus cable from the multiplus to connect to the usb dongle the Multiplus goes into "Low battery" and I cannot even detect the multi on any of the ports. Voltage is 13.3v measeured at the multi as shown on the Color control. Plug the ve.bus cable back in and all goes back to normal.
I assume this is occuring as a result of the multi having lost contact with the BMS and goes into a protection mode. How can I program the multi as the software instructions say to disconnect any accessories including the BMS?
