+DC-DC chargers are often triggered by the IGN circuit, but [[electrical:12v:voltage_sensing_delay|voltage sensing can be added]] to that circuit.  Others are triggered by chassis-side voltage alone.
 Dual-input (alternator + solar) units make charging source decisions that are sometimes quirky.  See below.
