NIST Mechanical Mezzanine: Existing PV System Components
Figure 1. Existing installation of two SMA Tri-Power inverters and combiner boxes, along with the remaining, downstream AC components. One combiner box and inverter pairing must be used as part of the eventually commissioned PV system. The second combiner box and inverter pairing must be used if the second, optional PV system is procured.
Figure 2. Different viewing angle of the same PV indoor components.
Figure 3. Straight-on viewing angle of the same PV indoor components
Figure 4. Line drawing showing the approximate location of the existing indoor components that are located in the mechanical mezzanine, a floor that is (nearly) level with the roof surface.
Figure 5. Existing, partial runs of conduit that are available for re-use by the installer. All existing conduit is located within the mechanical mezzanine.
