I'm having trouble getting some Brusa's to behave...

Thanks to multiple topics here and Damien's video's, got the software working, and learned from a video from Damien to set the maximum battery voltage as high as possible.

I need to charge to 475 volts, but at 450 volt the chargers drop out with a 'Batt Overvolt' error. I've had this before at a lower voltage, upping the max voltage to 720 helped...until reaching 450vdc where they drop out again.

unfortunately 720v is the maximum setting, and in CANbus mode there is not much else to set...

does anyone know how to fix this... (if not fixable I'll have to put the chargers in series, but I'd like to avoid this...)
