Green garbage. What the world needs is a decent battery with large 
storage capacity, light weight and lifetime measured in decades.
You able to design such a thing green-boi? Didn't think so.

Nonsense.

Off the shelf transformers have typical efficiencies of about 985, so no
gain there.

Frequency response is a red herring for power systems.

Requiring a specialized material for the core is likely to make the
transformers more expensive, not cheaper.

The size and weight of transformers is a tiny fraction of the total
size and weight of an energy collection, storage and power conversion
system. 

The size of a power transformer is dominated by the wire size needed
to handle the applied voltage and current.

If the location is that remote, it is unlikely that there will be roads
to tow in a trailer.
