Inverters are really quite good and getting better. Micro inverters (one per panel that output 240 VAC) Solve a lot of design problems and make it easy to expand over time. But going off grid is very costly with many tradeoffs. You have to really want it and educate yourself well.
If you are near North Carolina the Clean Energy Technology Center at NC State regularly offers pertinent classes online and in classrooms. I recently took two new ones on electrical storage for solar and operations and maintenance of solar installation. There are scholarships is you are underemployed. Other NABCEP classes are offered elsewhere. Off grid is a long road and will be a significant life style change. Attractive as it seems at first, I can't see it for myself so I am happy to use the grid for now. Things change and the utilities want customers. Who knows how it will shake out. Take the money you save using the grid and invest for when there is a clear advantage not just an emotional one. Maybe you won't need to go so far with it. If you are really remote the equation is different and the life style change already cooked in. Take some classes, there are so many choices how to do this and optimal varies a lot.

You avoid the cost, maintenance, and (slight) inefficiency of inverters, but are there significant disadvantages to this approach?
