Never hurts to have a big ass fuse between the batts and everything. Twice the size of your rectifier output. Dead short fuse of last resort type of fuse. Just to save your butt when doing wiring and you drop a wrench across some terminals.
In some battery plants I installed, we had these nice large knife switches with a big cartridge fuses built into the knife part. Allowed you to take the batts off line if you want. Nice to do if you are doing batter wiring, like replacing a cell or something.

You connect the batts and the load and the rectifier all in parallel. It should be set for giving you 54-55 VDC out. If the load, rectifier and batts are all on the same parallel circuit, then when the power is out, the batts provide the load current. When the power comes back on the rectifier powers the load and charges the batts. From: Scott Vander Dussen Sent: Friday, March 4, 2016 1:26 PM To: af@afmug.com Subject: [AFMUG] Eltek Rectifier Huh? Trying to figure these things out! I purchased and built an Eltek rectifier product using these products: CG1S-AUN-VC COMPACT POWER SHELF / REAR WIRE 200AMP MAX 48V UNIVERSAL OUTPUT POLARITY BC2000-A01-10VC 48V, SYSTEM CONTROLLER W/ ETHERNET, NEXTGENERATION, W/ CLEI V0750A-VC RECTIFIER, 840W, 53.5V, 15A, FAN COOLED (BOTTOM TO TOP) -INPUT: 90-264VAC It seems like this just takes AC power and gives me 48v DC out. I was expecting it would also attach to a battery array and provide charging of those batteries plus use their power source if grid power was lost. Am I totally wrong on that? I don’t see any method of connecting batteries to this power shelf :/ Noob out, Scott
