c-40 battery charging [RE-wrenches]

[Kurt Albershardt]

<x-flowed>
I strongly recommend fusing each series string, and have frequently added them to existing systems to permit servicing as well as add protection.  On the cheap side, you can bolt a fuse to a flag-style battery terminal and the cable to the other end of the fuse.  On the less limited budget jobs, we use pullout fuseholders with busbar material between (behind) them.  A rack of five or six pullouts can handle multiple inverters and battery strings, giving a nice, neat, and readily serviceable system.
