Enphase Energy, Inc.
PV Micro-inverter
3.
The Micro-inverters shall be plainly and permanently marked on a contrasting color background
where readily visible with the following:
a.
Manufacturer's Name,
b.
Model designation,
c.
Serial Number,
d.
Complete input and output direct current (DC) and alternating current (AC) electrical ratings
in Volts, Amperes/Watts,
e.
"Maximum branch circuit protection: 20A",
f.
Operating ambient temperatures "-40 C to 65 C",
g.
Current CSA listing required markings or labels.
4.
If the listing of this PV Micro-inverter, under CSA Certificate number 2395707 and UL Listing
number Q1KH.E341165 is no longer current, the approval of this Research Report may be suspended
or cancelled subject to Test Lab's evaluation.
5.
Micro-inverters shall be supplied from a dedicated 20 Ampere AC branch circuit without GFCI or
AFCI protection.
6.
The Micro-inverter shall be installed and maintained by "Qualified Person" as defined in the Los
Angeles Electrical Code and in strict compliance with manufacturer's instructions.
7.
The maximum number of Micro-inverters in a 20 Amp circuits shall not exceed the following:
Model Number
M250-60-2LL-S2X
M250-72-2LL-S2X
M215-60-2LL-S2X-IG
*
See Item #1for model designation details
**
Refer to manufacture's installation instructions.
8.
The hardware used to mount the Micro-inverter to the racking system shall be of a corrosion resistant
type.
9.
The power source to the engage cable shall be de-energized prior to servicing.
10.
The PV racking system shall be provided with grounding means (ie. ground lug) for termination of
the equipment grounding conductor that is independent from the Micro-inverter. The WEEB
connector shall not be relied upon as an approved equipment bonding jumper or equipment
grounding conductor.
