DC via Direct Burial Romex

[SolarAmateur]

I have some 10/2 direct burial romex already run underground about 50 feet to an outbuilding. I would like to place two 375w solar panels on the outbuilding and send the solar power back to the house. It will be about 100 vdc at a max of 10 amps.

Any obvious problems?

Once in the house I would like to run it in the basement rafters to my solar charge controller, battery and inverter, still 100 vdc at 10 amps.

I don’t think romex is code inside the house for this purpose?

Should I use THHN in conduit or ???

Thanks in advance for any help.
