Microgrids FAQs

What is a Migrogrid? 

Microgrids are small-scale versions of the electric grid within a facility. At a facility-central location, power conversions and control commands are made from which power is distributed to loads (such as LED lights). Doing so makes the use of high-efficiency power converters and state of the art controls economically practical.

 

Why should we consider implementing Nextek's microgrid system?

The Nextek Microgrid solution is custom designed to:

  • Shorten the return on investment (ROI) period of LED lighting system

  • Provide a safe and flexible working environment in which lights can easily be reconfigured

  • Provide a more robust control infrastructure to building managers and the end user

  • Make smart controls financially accessible to new buildings and retrofit projects by reducing the number of control units needed per square foot

 

What is the cost of microgrid compatible products compared to their traditional scattered infrastructure alternatives?

Comparable. The cost of Microgrid components (luminaires, wiring, controls, devices) is comparable to their traditional equivalents. In most cases they are the same device with only the power input circuitry altered to operate on DC power. Certain Microgrid devices may also be less expensive because they do not need an internal power converter.

 

Can microgrid fixtures be wired together in a single run (daisy-chain), or do they need to be wired in dedicated runs back to the PSM unit (microgrid power supply)?

The Nextek PSM unit can supply each of its 16 channels with up to 95 watts. This could accommodate multiple lower wattage fixtures in a daisy chain arrangement, which is then connected to the PSM channel.
