DC Power Systems
Nextek Power Systems’ power servers reduce energy costs by employing Direct Coupling® Technology to use energy from the lowest cost sources first. 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 such as DC fluorescent lighting, motor controls, and more. Since the system never changes the power to AC it avoids power-robbing conversions, grid interconnection issues, and often requires no utility permitting. Low-voltage controls allow lighting to be more easily connected to occupancy sensors, low-voltage switches, and wireless 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 System include:
- Buildings with large, flat roofs.
- Locations operating fluorescent lights that are always on during the daytime like retail, grocery, and offices.
- Businesses that benefit from having the power stay on during an energy grid failure.
- Buildings with motors that utilize variable frequency drive motors (VFDs).
Areas where utility rates or demand charges are high or where net-metering is not encouraged.
The Nextek Power System directly couples Nextek’s high-efficiency DC ballasts, DC fans and other DC devices to DC power sources.
24V and 48 V power configurations are possible with Nextek Power Systems.
