While not recommended for any length of time, you can power up the MPPT by connecting an appropriate voltage power supply to either the battery or PV terminals for testing.

The MPPT can be powered from either.

The MPPT is designed to be connected to a battery and solar panels, so that is the preferred supply to test with if possible.
