You&#x27;ll want to think long and hard about how you&#x27;re going to deal with fuses. For the kind of currents that batteries can put out it can be quite expensive to properly fuse things.<p>50V was a fairly arbitrary voltage deemed to be &#x27;safe&#x27;, however there are cases known of people dying from 50V and even lower (in particular, one very nasty accident involving a Swiss ham in pre-internet times).<p>A bus made of thick copper wire would be stolen here pretty much on the day that you installed it (copper theft is on the order of the day).<p>I&#x27;m not convinced of the need to have any of this though, I got my power usage down to the point where a fair sized house ran year round from 16 solar panels and a small windmill. The year that we only had the solar panels we still needed the genset with some regularity but the year the windmill went up we used it only twice (when I was running a 12KW plasma cutter from the battery pack they tended to deplete a bit too quickly...).
