Hi Richard, a quick first response.

A few months ago there was an extended conversation on-line on the Sustainable Energy Forum (do others know about this group?) lead by the doyen of solar water heating in NZ Arthur Williamson of Chch which discussed a cut down PV system. Rather than an inverter, direct current from PV would heat a (second?) coil in the hot water cyclinder. I’m now a bit hazy on the details and have no idea if it is possible to retrieve the various posts on this which discussed technical issues. Could this be relevant?
