Product FAQs
Q1: What is the difference between this model and the B2B241260?
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.
