It is Bluetooth Smart enabled, it has two outputs to charge 2 battery banks. The charger compensates for voltage drop over the DC cabling by slightly increasing output voltage when the DC current increases. With boat owners in mind this adaptive 5-step charger can provide either 30A or 50A of charge to each of three battery banks. Or the Phoenix 1+1 model provides 3A to the starter-battery, the rest to the ‘house’ bank. 24V models are available with 16A/25A charge. Bluetooth enabled, you can monitor the charger and set alarms straight from your phone. Adaptive, intelligent, dynamic charge features – see the datasheet below.
