SOC on Cerbo GX shows "---". Was reading fine prior to a low-voltage alarm. Charged the batteries with boat engine alternator, but still no SOC reading. What now?
Lynx shunt, cerbo GX with screen, 3 lithium batteries (200 ah x 3) & Victron Smartsolar MPPT 150/60. System was working, prior to a low-voltage alarm. The cerbo appeared to reset showing the device list, then back to the normal screen, but with no SOC "---".
You have to make a full charge cycle.
