If installing in areas with ground snow loads greater than 40 psf,
install MLPe devices directly next to module frame edge
SYSTeMS USING eNPHASe MICROINVeRTeRS OR SUNPOWeR AC MOD-
IronRidge systems using approved Enphase products or SunPower modules eliminate the need for lay-in lugs and field
installed equipment grounding conductors (EGC). This solution meets the requirements of UL 2703 for bonding and
grounding and is included in this listing.
COMPATIBLe PRODUCTS
Sunpower
Modules with model identifier 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
.
enphase
Microinverters M250-72, M250-60, M215-60, C250-72, and engage cables eTXX-240, eTXX-208, eTXX-277.
➢
A minimum of two inverters mounted to the same rail and connected to the same engage cable are required.
➢
The microinverters or Sunpower AC modules must be used with a maximum 20 A branch rated overcurrent protection device (OCPD).
➢
If an AC module is removed from a circuit for maintenance, you must first 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.
On AP systems equipment,
remove Grounding Washer
