Coleman Air makes a 100 amp diversion control. The Morningstar Tristar and xantrex C60 also do it. David Katz

I have put thought into this and have a simple solution but need to know if it is worth while marketing it. Carl Emerson Free Power Co.

This is a problem I have struggled with for ages. We do not get credit for export so I have been looking for a good use for free electricity, have not found one yet.

Anything we use on site is worth 100%, any production that goes back to the grid is lost forever to the customer. What we would like to do is monitor all solar and wind production, monitor all usage, and then be able to dump every watt-hour of over production as heat, there is plenty of (thermal) storage capacity. If this were a battery based system I know how I would approach this and what equipment I would spec, but so far I am having a hard time coming up with a solution. Anyone have any suggestions for products or strategies in this case? Something like an eGauge with programmable PWM relay outputs?
