Is an off-grid node possible?



Working towards financial independence and educating myself on BTC everyday. This sub has been an excellent resource for random questions, except I cannot find any old posts discussing off grid nodes.

In order to conserve power, I will not be able to have a connection to the internet on 24/7. Is it still possible to gain the benefits of a node (privacy of my transactions) if I only have it on 3-4 hours a day?

I will be slowly adding to my battery bank and hopefully experimenting with micro hydro electricity this year, so down the road I will easily be able to run certain things 24/7.
