There has been a recent problem in that my Quattro is showing a voltage detection error. It thinks the battery voltage is 6.5V although everything else (the battery monitor, a Venus GX, and my multimeter) says the batteries are normal at 12.8V or thereabouts. The quattro will now invert OK but won’t charge.
Can you suggest what might be wrong? I have checked the connections to the battery and they all appear good. And the inverter is working OK so that connection must be good.
Where are the settings to control where the VE Bus picks up voltage and state of charge? And then how to make the Quattro use those?
