    To prioritize charging from the charge controller, set the Charge Controller Absorb and Float voltages at 0.2 Vdc (24 V Nominal Systems) and 0.4 Vdc (48 V Nominal Systems) higher than the inverter settings. Under lightly loaded conditions, power charging devices may not regulate their voltage well and may cause voltage fluctuations that rise above the battery operating limits.
