Then it may be financially unsuitable to go with a DC system. There's nothing wrong with the way you have it set up, there's just a part of my brain that doesn't like inverters. In some cases they are a good solution, but I hate having extra math in the equation.
Not necessarily financially unsuitable. Depends on how the system is set up.
I just don't know how one would run it DC 24/7 without it being complicated.
