Converter 110 volt Input Current
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 ...

That doesn't sound normal. I believe a double bulb light fixture takes 3A dc, or about 39W. Converter efficiency is about 80%.
AC power is 39W/0.8 = 49W
AC current is I = 49W/120V = 0.4A
I would check the meter accuracy. Plug a 100W light into the ac receptacle. AC current is 100W / 120V = 0.83A.

I just noticed as I turn on each 12 vdc light, the input current reading on the PI EMS (110 volt line side) to the converter jumps up approx. 1 amp for each light.
