Shunt resistor right application?

  1. Aug 24, 2010 #1
    I have a 400A (125VDC) charger that feeds a battery bank and a few DC panels (critical). This poor design has the panels being fed from the high side of a 600A breaker that is between the charger and battery bank. I need to take the battery off line for a load test but the problem I'm going to have is when I reconnect the battery to the charger I will have a current surge coming from the 400A charger to the unenergized battery bank (approx. 350A). This will most probably cause a voltage drop in the DC panels which I CANNOT have (critical loads on panels). Will a proplerly sized shunt resistor between the disconnect switch and panels work for this situation?
