Converter 110 volt Input Current

[otrfun]

Noticed the 110 volt input current to my converter fluctuates significantly with load. When the battery is fully charged, sometimes the 110 volt input current jumps from 1-2 amps to 6-7 amps by just turning on 4 or 5, 12 vdc lights. Is the converter simply reacting to the voltage drop (from the increased 12 vdc load) and increasing charge current/voltage to compensate? I assume this is normal? Thanks!

My converter setup very seldom drops input 120VAC up and down but have heard some do. It might be a good idea to check the fluids in your battery setup. This is one thing that might lead to a shorted cell in your battery and start drawing alot of current from the battery side which will draw more current from the 120VAC side trying to keep up...
