@smithlabs I came into the solar stuff knowing a good bit about DC power, electronics, wiring, inverters, AC electrical 'best practices' and low voltage systems in general but even with all of that I wish I had at the time had someone like you that I could ask questions of and get good advice from. I am not sure @ganjafarmer knows how fortunate they are to be getting advice from both a hack like me and a pro like you.
Experience is NO hack! He can gain by both views; many minds cover problems better. I enjoy every solar system, complex to simple, and everywhere in between! It is fun to see how some things are solved in novel ways, every now and then I can use their solution to fix my own, or someone else's, problems. :)
I intend to run 24 volts myself, because it is the highest voltage I can get decent priced on power inverters.
I hear you there. I was actually using 'hack' in the best sense of the word. :)
I have been leaning towards putting together a 24 volt system because my charge controllers support both 12 volt and 24 volt systems and one of my panels is actually a 24 volt panel but I have been using it on a 12 volt system. I really only need to get a pair of matching batteries (or one 24 volt forklift battery) to have a 24 volt system. The major appeal for me with 24 volt is that it can run a larger watt inverter. I don't really use anything that needs a larger inverter but I like having the option. I have mainly stuck with 12 volt because I like the simplicity but most forklift batteries are 24 volt so between that and the option of running a higher watt inverter I am definitely thinking it over.
I have about 300 Amps at 24 Volt of LiIon cells. I am about 1/3 of the way where I want to be at 21,000 watts (900+ Amps at 24 Volts). All my inverters are 24 volts, and my smallest in 1500 Watts.
That is going to be one whopping battery bank when you are finished. Are you going so high with your watts so that it can handle a whole house startup surge? It seems like 10,000 watts is all that is really necessary if you discount the initial startup of refrigerator compressors etc.
A straight 24 volt feed with outlets etc? If so that is what I have been planning to do with 5 volt DC because I can use small gauge wire and standardize all my plugs/outlets to USB to run fans, lights and charge small devices.
Ahh that makes sense. Thanks again for your valuable insights. :)
Happy to help! Any time.

I also plan to run 24 volts into the house for lighting and low power applications.
