TPM46 Enphase M215 Inverter on a TPM Rack

This supplement covers how to attach an Enphase M215 Microinverter
(Inverter) to the Rails of a TPM (Top-of-Pole-Mount) rack. For detailed
information on installing the M215 Inverter; including cabling etc., refer to
the Enphase publication titled “M215 Microinverter Quick Install Guide” or
other relevant Enphase publications.
The Inverter attaches to the Rails using 5/16" hardware. Attach the Inverter to
the Rail at the approximate centers of the PV Modules. (See Figure 1)
A. Mark and then drill a 11/32" hole through the Rail where the Inverter
will be attached. (See Figure 2)
B. Attach the Inverter to the Rail and tighten securely. (See Figure 3)
