I have a Xantrex Freedom HF 1800. I recently acquired a transformer that is changing the 220VAC European shore power
to 110VAC. Actual measurement on the 110VAC side is more like 127VAC. Of course it is still 50 cycle rather than 60 cycle. The transformer is rated for 4,000 Watts - more than the 30 Amp shore 110VAC.
My problem is that the unit senses the shore power
(the yellow light flashes) but will not switch over to start charging
the batteries. I have found no useful information on the Xantrex site.
