FCC Compliance
This equip ent has been tested and found to co ply with the li its for a Class B digital device,
pursuant to part 15 of the FCC Rules. These li its are designed to provide reasonable protection
against har ful interference in a residential installation. This equip ent generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
ay cause har ful interference to radio co unications. However, there is no guarantee that
interference will not occur in a particular installation. If this equip ent does cause har ful
interference to radio or television reception, which can be deter ined by turning the equip ent
off and on, the user is encouraged to try to correct the interference by one or ore of the
following easures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equip ent and the receiver.
• Connect the equip ent into an outlet on a circuit different fro that to which the receiver
is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or odifications not expressly approved by the party responsible for co pliance ay
void the user’s authority to operate the equip ent.

The Siemens Microinverter System
The Sie ens Microinverter Syste is the world’s ost technologically advanced inverter syste
for use in utility-interactive applications. This anual details the safe installation and operation of
the Sie ens Microinverter.
The three key ele ents of a Sie ens Microinverter Syste are:
• the Sie ens Microinverter
• the Envoy™ Co unications Gateway
• the Enlighten™ web-based onitoring and analysis syste
This integrated syste axi izes energy harvest, increases syste reliability, and si plifies
design, installation and anage ent.

Page 6 Copyright 2011 Siemens Industry, Inc. 141-00015, Rev 01
How the Microinverter Works
The Sie ens Microinverter axi izes energy production fro your photovoltaic (PV) array. Each
Sie ens Microinverter is individually connected to one PV odule in your array. This unique
configuration eans that an individual Maxi u Power Point Tracker (MPPT) controls each PV
odule. This ensures that the axi u power available fro each PV odule is exported to the
utility grid regardless of the perfor ance of the other PV odules in the array. That is, although
individual PV odules in the array ay be affected by shading, soiling, orientation, or odule
is atch, the Sie ens Microinverter insures top perfor ance for its associated PV odule. The
result is axi u energy production fro your PV syste .
System Monitoring
Indoors, you can install the Envoy Co unications Gateway by plugging it into any convenient
120Vac wall socket and providing an Ethernet connection to your broadband router or ode .
After installation of the Envoy, the Sie ens Microinverters auto atically begin reporting to the
Enlighten web server. The Enlighten software presents current and historical syste perfor ance
trends, and it infor s you when the PV syste is not perfor ing as expected.
Optimal Reliability
Microinverter syste s are inherently ore reliable than traditional inverters. The distributed
nature of a icroinverter syste ensures that there is no single point of syste failure in the PV
syste . Sie ens Microinverters are designed to operate at full power at a bient te peratures as
high as 65° C (150° F). The inverter housing is designed for outdoor installation and co plies
with the NEMA 6 environ ental enclosure rating standard:
NEMA 6 rating definition: Indoor or outdoor use pri arily to provide a degree of
protection against hose-directed water, and the entry of water during occasional
te porary sub ersion at a li ited depth, and da age fro external ice
for ation.
Ease of Design
PV syste s using Sie ens Microinverters are very si ple to design and install. You will not need
string calculations, and you can install individual PV odules in any co bination of odule
quantity, type, age and orientation. You won’t need to install cu berso e centralized or string
inverters. Each icroinverter quickly ounts on the PV racking, directly beneath each PV
odule. Low voltage DC wires connect fro the PV odule directly to the co-located
icroinverter, eli inating the risk of personnel exposure to dangerous 600 Vdc power.

DANGER Hazardous voltage. Will cause death or serious injury. Turn off
Power before working on this equip ent. Be aware that installation of this
equip ent includes risk of electric shock. Nor ally grounded conductors ay
be ungrounded and energized when a ground fault is indicated.
WARNING: Before installing the Sie ens Microinverter, read all instructions
and cautionary arkings in the user anual, on the Sie ens Microinverter, and
on the photovoltaic array.
WARNING: Perfor all electrical installations in accordance with all local
electrical codes and the NEC

, ANSI/NFPA 70.
WARNING: Connect the Sie ens Microinverter to the electrical utility grid only
after receiving prior approval fro the utility co pany.
WARNING: Be aware that only qualified personnel should connect the Sie ens
Microinverter to the electrical utility grid.
Compatibility and Capacity
The Sie ens SMIINV215R60XX Microinverters are electrically co patible with ost 60-cell PV
odules. For ore infor ation, see Technical Data page 25 of this anual.
Refer to the Sie ens website (http://www.usa.sie ens.co / icrosolar) for a list of electrically-
co patible PV odules and approved PV odule racking syste s. To ensure mechanical
co patibility, be sure to order the correct connector type for both icroinverter and PV odule
fro your distributor.

d. Bend the individual wires back into the recesses
in the wire holder so that they angle back toward
the cable.
e. Cut the individual wires so that no excess
extends outside of the wire holder. The portion
that angles back will need to extend enough to
fit neatly into the 0.5 c (0.2 in) slot in the wire
holder and flush with the edge of the cap.
f. Insert the wire holder into the cap, and screw
the gland portion onto the cap. Ensure that the gland portion is rotating, not the
cap.
g. Hold the cap with an Sie ens disconnect tool, or insert a #2 Phillips screwdriver.
Hold the gland portion with a 24 (7/8”) wrench. Tighten the gland portion until the
ratcheting feature on the cap botto s out.
h. Attach the ter inated cable end to the racking using a clip or tie wraps so that the
Trunk and Drop Cable and ter inator do not touch the roof.
