I have a Quattro 12/5000/220 inverter/charger connected to 4 Victron Lithium 330Ah batteries including a Lynx smart BMS and Cerbo GX. When the 11Kva Onan generator is running the Quattro will never go higher as 168Amp charging capacity to the batteries. The same when the Quattro is connected to the shorepower. Why can we not charge higher as 168Amp??
