Monitor One internal Vin

I just got my monitor one and looking for less evasive ways to add a solar battery I have for my cell camera. What are the specifications on the white Vin connector on the green (Tsom?) board.

Electrically it's the same as VIN on the expansion card. If are using the I/O expansion card, it's the same as the B8B-PH and the M12 8-pin.

However, there is one difference: The 2-pin connector on the base board is rated up to the full capabilities of the power supply: 6 VDC to 90 VDC.
