Hello,
a 3-phase ESS with three MultiPlus II 48/3000 (Firmware 497) and a Cerbo GX (Firmware 2.91) working for a month without a problem - now getting a VE.Bus Error 11 - 0x800016 - BF safety test OK - Communication error.
I already double-checked my Wiring and all the error 11 steps from https://www.victronenergy.com/live/ve.bus:ve.bus_error_codes. Could anybody give me a hint on this?Cheers, Peter
