Use the PTP650/ PTP670 AC+DC Enhanced Power Injector with the PTP 550

Hello all,

Is it possible to use the PTP650/ PTP670 AC+DC Enhanced Power Injector with the PTP 550. The reason I ask is because we are going to power a remote location with solar energy, and access to AC is limited, unless we install an inverter. We'd like to use the DC input in the power injector to power the PTP550 radio directly.
