GROUND MOUNT INSTALLATION MANUAL - 11©
2019 IRONRIDGE, INC. VERSION 2.1
MICROINVERTER KITS
Microinverter Kit
(80 in-lbs)
Use IronRidge's Microinverter Kit to bond compatible
microinverters and power optimizers to the racking system.
Insert Microinverter Kit T-bolt into top rail slot. Place
compatible microinverter or power optimizer into position
and tighten hex nut to 80 in-lbs.
Þ If installing in areas with ground snow loads greater than 40
psf and underneath a module, install MLPE devices as close as
possible to module frame edge.

SYSTEMS USING ENPHASE MICROINVERTERS OR SUNPOWER AC MODULES
IronRidge systems using approved Enphase products or SunPower modules eliminate the need for lay-in lugs and eld
installed equipment grounding conductors (EGC). This solution meets the requirements of UL 2703 for bonding and
grounding and is included in this listing.
The following Sunpower modules are included in this listing: Modules with model identier Ab-xxx-YY and InvisiMount
(G5) 46mm frame; where "A" is either E, or X; “b” can be 17, 18, 19, 20, 21, or 22; and “YY” can be C-AC, D-AC, BLK-C-
AC, or BLK-D-AC.
The following Enphase products are included in this listing: Microinverters M250-72, M250-60, M215-60, C250-72, and
Engage cables ETXX-240, ETXX-208, ETXX-277.
Þ
A minimum of two inverters mounted to the same rail and connected to the same Engage cable are required.
Þ The microinverters or Sunpower AC modules must be used with a maximum 20 A branch rated overcurrent protection device (OCPD).
Þ If an AC module is removed from a circuit for maintenance, you must rst disconnect AC power and then install a temporary EGC to
bridge the gap by inserting an AC extension cable (or via other NEC-compliant means), in order to maintain effective ground continuity to
subsequent modules.
SYSTEMS USING PHAZR MICROSTORAGE PRODUCTS
Bonding and grounding is achieved via the IronRidge
system when using the Microinverter Kit. Running a
separate equipment grounding conductor to the PHAZRs
is not required.
