Hey all, beginner here with a dumb question: I'm using the experience I gained from a 12v system I built in my detached garage/workshop to start building out my main house for solar as well, and had a question about bus bars. My plan is to set up six 24v 200Ah LifePO4 batteries in parallel, along with an 80A charge controller and two 4000W power inverters. I've already made sure everything's properly sized and have fuses for all the right places, but whereas I I wired one battery to the next in parallel in the 12v system, I was looking to make my life easier with the 24v system by using bus bars. Only problem is that, by my count, I have 9 separate components and most of the bus bars I see have a max of 4-6 actual terminal screws.
Is it possible/safe to "daisy chain" multiple bus bars together to "expand" the capacity enough to support these components? My thought was maybe connect three batteries each to two pairs of bus bars (pair meaning one positive one negative), have a third bus bar pair that I connect the charge controller and inverters to, and have each of these bus bar pairs connect to a "master" pair of bus bars, this way everything is still in parallel, and of course I would make sure that the bus bars I use would support the current and voltage that would be going through them in this setup. Of course, if this is either inefficient or a good way to ruin my stuff or blow my house up, I'd like to know that ahead of time as well.
Thanks in advance to anyone who can provide some guidance on this!
