The'--nphase" M215 Microinverter with integrated ground delivers increased energy harvest and
reduces design and installation complexity with its all -AC approach. With the advanced M215, the DC
circuit is isolated and insulated from ground, so no Ground Electrode Conductor (GEC) is required
for the microinverter. This further simplifies installation, enhances safety. and saves on labor and
materials costs.
The Enphase M215 integrates seamlessly with the Engage' Cable, the Envoy" Communications
Gateway", and Enlighten Enphase's monitoring and analysis software.

SOLARLOK Grounding Bolt
These boles are designed for solar module grounding applications using solid copper uninsulated
6 AWG to 12 AWG wire. or stranded copper uninsulated 6 ANG to 10 AWG (7 or 19 strands) wire.
The grounding assembly consists of a wire bolt (wire slot on one end and threaded post on the
other). wire binding hex nut and mounting lock washer nut. The grounding assembly is used
with acetal -framed photovokaic (solar) panels and related products that require grounding for
safety reasons.

APPLICATIONS
Solar parcels arta related photovoltaic products require grounding per the National
Electric Code (NEC Article 690.34). These applications include. but are not limited
to electrical grounding of solar modules and solar roof tiles.
ELECTRICAL
Short Term Current Test (UL 467)
6 AWG = 1530A (6 seconds). 8 AWG = 1180A (4 seconds)
10 AWG = 750A (4 seconds). 12 AWG = 470A (4 seconds)
MECHANICAL
Secureness Test (UL 49SAi):
6 AWG = I8 lbs (3U minutes). 8 AWG = 8lbs (30 minutes)
10 AWG = Sibs (30 minutes). 12 AWG = 51bs (30 minutes)
Pull out Test (UL 496A -B):
6 AWG = 100 Itis (I minute).8 AWG = 90 Itis (1 minute)
