This model adds MPPT solar charging to the 24V-to-12V DC-DC charging function. Q2: Can I connect solar panels directly? Yes, through the solar input. Keep the array within the charger’s power and voltage limits, allowing for increased panel voltage in cold weather. Q3: Is it compatible with LiFePO4 batteries? Yes. Select the correct profile and ensure the battery has a suitable BMS and can accept the charging current. Q4: Does 60A DC-DC plus 50A solar mean 110A charging? No. These are separate source ratings and should not be added together as a combined output rating. Q5: Can it charge from 240V mains? No. A separate AC battery charger is required. Q6: Does vehicle charging need an ignition connection? Yes. Connect the D+ control input as directed in the manual. Q7: Can I use it with a 12V vehicle? No. This model is designed for a 24V vehicle supply. Q8: What should I check before installation? Check alternator capacity, battery charging limits and solar array specifications. Have a qualified installer select suitable wiring, fuses and mounting arrangements.
