Does the Multiplus act as an autotransformer shore/gen 120v ac input?

I see on the data sheet for the multiplus 24v 3000w inverter/charger that in the "inverter" section it list output as 120VAC +/- 2% and under the "charger" section, the input is 94-140VAC. Does that output apply to inverted loads only, or does it act as an autotransformer and convert (for example) 100VAC shore/gen power up to 120VAC as well? I'm trying to figure out if I should install a separate autotransformer in the RV to account for some RV parks voltage dropping below 110v during periods of high demand. Thanks in advance.

Hi @dabean80,

The output applies to inverter loads when connected to a battery and there is no AC-input.

The multi output voltage will be equal to the input voltage.


The autotransformer applies a *small* voltage boost for exactly the situation you describe.
