I should have mentioned that if 24v system was used then this might
just work.
I know the the inverter is around 90% efficient, but the main idea was
to support a low wattage solar panel until money would allow the
purchase of much larger system. Another idea I had was to help
charge up the batteries (from very overcast days) to make best use of
Economy7 and charge the batteries over night from the mains.
