  2. 2. DC MICROGRIDSDC MICROGRIDSDC Microgrids enable significant energy savings and thesimple integration of advanced power generationtechnologies.Many modern appliances such as laptops, LED lightingand communications equipment run on DC power (thetype provided by batteries), yet we plug them in to the ACmains.Also renewable technologies such as solar photovoltaicsand wind power become more prevalent at a householdlevel, DC microgrids could be a cheaper and more efficientalternative.EMerge Alliance Corp - ©2009-2010
  3. 3. DC MICROGRID BENEFITSDC MICROGRID BENEFITS1) Reduced energy costs2) Security against higher utility costs3) More efficient energy use (10% to 40%)4) More reliable service5) Safer power at 24v6) Highly scalable system designs7) Reduced future renovation costs8) Measured 50% reduction in installation, moves and changesEMerge Alliance Corp - ©2009-2010www.nextekpower.com/case-studies/direct-coupling-dc-microgrid
