Hi Steve;

I believe the OP wants an output from the charge controller to be 110 volts (you are right, that input to the one you listed can handle over 100 volts from the solar cells, but the output can not).

I guess I'm not sure why the 'commitment' has to be that high of a DC voltage. The new charge controllers, especially the MPPT technology, gives a much more effecient charge to the battery and is better for their long term life IMO (basically the relay is creating an older 'shunt' style controller, and that's if it's monitoring battery voltage as a feedback).

I'm not a solar expert, but have dabbled in that technology for remote weather station power (although it was just 12 volt system).
