Abstract
A UPS with a multi-port DC bus operable to couple a plurality of intermittent external DC sources and intermittent external DC loads is disclosed. The invention includes renewable energy power systems with a UPS having a multi-port DC bus and a responsive energy storage means electrically coupled to the multi-port DC bus. An embodiment includes a renewable energy power system with a UPS having a multi-port DC bus having an external DC load coupling for supporting an external DC load. Exemplary DC sources disclosed include a pole-mountable wind turbine assisted by ducted hot air created by the waste heat from a solar-voltaic array that is also an exemplary DC source. A parking lot solar power system is also disclosed that is both a DC source and at least one DC load. A cogeneration system using the AC output of the UPS and the AC output of a genset is provided.
