Hi MrWizard,
The Sola does automatically switch boost levels.
From the factory the levels are set at:
When voltage input is 110 it does 10%
When voltage input is 100 it does 20%
When voltage input is 90 it does 30%
What that means in real life is that if input voltage is 108 the output will be boosted to about 118. If input voltage is 101 then output voltages would be about 111 volts.
If input drops to 98 then output becomes in theory 117.
The lowest input voltage I've measured is 97. It boosted the voltage to a safe level for running the roof air. I did document that on the boards but I can't find it.
I'm told there is a "pot" that can be turned to change the set points. I'd love to move the initial boost point up to 113 volts. Unfortunately that is beyond my knowledge base.
I'm using it at the moment on a weak 30 amp shore power supply. Output voltage is 115.8 volts.

i'm sure the Sola he has is NOT automatic
it can do boost or buck
but it has taps and you manually set it for the amount of boost or buck
he has detailed this numerous times
he has it on boost (i forget the amount) if line voltage suddenly went up
so would the voltage to the RV, thus an EMS is needed
the same if the voltage went too low the Sola would continue with the same amount of boost, and the RV voltage would be TOO LOW
