Posted January 12, 20232 yr According to the spec sheet, the VM 1000W Axpert can only charge at 20A from AC. My 12V LiFePO4 batteries recommended charge rate is 50A. Can I connect a 24V, 20A power supply to the PV-IN of my axpert to increase the total charge rate?

The solar charge controller is expecting high impedance panels; a power supply is low impedance. So the MPPT would not be able to control the power flow.
