I have a system containing
1: Quattro 48/10000/140-2x100

2: Lynx Distribution system(DC in, Shunt, BMS, Distributor)

3: SmartSolar MPPT VE.Can 250/100 rev2

4: Color Control GX

5: Battery bank 400 Ah Smart Lithium batteries

When i start the system with the Quattro Charge i get

Error #15 - VE.bus error

The inverters Bulk+ Iverting flicker Absobtion steady, after a while Quattro is off and it all start again.

If i put the quattro to on Low battery is lit (measured battery voltage > 54V) and after that the same as when quattro in charge only occur.

Ooopps !!!. I got today exactly same results in from the grass installation, both the VE-Bus error #15 and Low Battery Voltage error (Voltage is 50,5 Volts, so OK not low) . Quattro 48/10K and Pylontech batteries. Any clue?

Hi, could it be that your Multi is configured for having a VE.Bus BMS (which is a very specific type of BMS; which you don’t have in your system) ?

Thats one of the reasons for the error 15:

Multi configured for having a VE.Bus BMS installed, but receiving commands from a BMS elsewhere, connected to the GX Device, ie via DVCC.
