Hi, IM relatively new to the solar space and this forum has already helped me greatly in understanding most of the important stuff. There are still some things I am not completely sure about yet, though.
What I can't seem to grasp is how to charge a single battery with high wattage of, for example, over 20KW. Would it be preferred to go with a 48V or 96V battery? At 48V, 20KW would be nearly 500A. Is there even a BMS that can handle that? If you go with a 96V battery, though, my questions is; where do you find 96V MPPT charge controller? And what if you want to double the power to 40KW? My guess is you would split up the solar array into multiple independent ones to charge independent smaller and lower voltage batteries, but then they might differ in voltage and couldn't be used together.
Sorry if this doesn't make any sense, but it is really confusing for me how people with large arrays deal with this.
