Hi,
I would go with the Grape solar charge controller. I'd move to a 24 volt battery bank. I'd add a 24 volt inverter.
That would simplify the solar system albeit I would now have 5 pair of panels in parallel. I've found I almost always have at least 1 or 2 panels partially shaded at different times of the day so I prefer keeping each one paralleled if possible. While a 24vdc inverter makes sense, most of my battery use would be 12vdc so I'd end up with a constant conversion loss there that might be more of a downside than would be offset by the higher voltage system for the solar and inverter.
As for the Grape controller, It would be simple, and desireable for the 12vdc conversion capability, I'm not sure 40amps would be sufficient for the auto level/slide hydraulic pump. It tends to draw quite a bit of current, especially in colder weather and is voltage sensitive, shutting down easily if the voltage is to low. I'm also not sure I'd like giving up some of the charging adjustment capability the SC2030 gives me. Of course I wouldn't need to add another SC2030 to my setup if I stepped up to 24vdc, and I could add a 24vdc to 12vdc converter, but I'm not sure it would be worth it since 98 percent of the time I'm using my inverter I'm using it to output quite a bit less than 200 watts, and thus not putting much of a demand on my battery system. A 12 volt system seems to handle that well.
