I have a new Widebeam canal boat which has a complete Victron system.
Cerbo GX with screen, 2 solar chargers, inverter, smartshunt, galvanic isolator and 3 200ah Lithium batteries.
My problem is when charging from the alternator on the engine the battery indicator on the Cerbo only goes up by say 10 to 20 % after 6 or 7 hours of cruising. The voltage get to 14.2 volts and the alternator stops charging but the meter on the screen only shows 30 to 40% charged. If however I charge from a portable generator the boat fully charges in about an hour and a half and the indictator shows 100% charge
Is there a setting that needs to be changed, I have contacted my supplier several times, but having no joy.
