Nextek Power Systems - Detailed
NEXTEK's power system reduces energy costs
by using energy from the lowest cost sources first.
For a graphic demonstration using flash video, please click here.
The system uses all available energy from locally generated
sources (such as photovoltaic cells) first, then 'fills
in' with power from the grid or, when the grid is not
available, from batteries.
Power generated as DC (direct current) is used as DC
to support fixed DC loads in the building such as DC
fluorescent lighting, motor controls, and more. Because
the system never changes the power to AC, it avoids
inverter losses, grid interconnection issues, and often
requires no utility permitting.
Low voltage control features allow lighting to be more
easily connected to occupancy sensors, low-voltage switches,
and local or remote energy management systems. The low-voltage
control wiring makes it safer and less expensive than
traditional switching and control systems.
Locations that are ideally suited to the Nextek Power
- One, two, and three story buildings with large,
- Locations operating fluorescent lights that are
always on during the daytime like retail, grocery,
- Businesses that benefit from having the lights stay
on during a power failure.
- Buildings with motors that utilize variable frequency
motor drives such as the AB Powerflex series.
- Areas where utility rates or demand charges are
high or where net-metering is not encouraged.
The Nextek Power System Directly Couples® Nextek
high-efficiency DC ballasts and other DC devices to
DC power sources. The NPS-1000 takes DC power from solar
panels or other DC power sources, adds any necessary
AC power from the grid, and powers selected loads with
highly efficient DC power.
