Prior to touching any part of the inverter use care to ensure surfaces and equipment are at
touch-safe temperatures and voltages before proceeding.
Anytime the inverter has been disconnected from the AC utility grid, use extreme caution

ocation of safety notices and labels
Note the location of safety notices on the MICRO inverter. Labels must not be hidden with
external objects or parts such as rags, boxes, or other such equipment. They should be
cleaned periodically and always maintained in view. Technical data in this manual does not

A
ppropriate usage
The MICRO inverter is designed to transform direct current (DC) coming from a photovoltaic module (PV) into
an alternating current (AC) suitable for being fed into the power distribution grid.
‡
The operating current output during the normal operation MUST NOT exceed the limits documented in the
WHFKQLFDOVSHFL¿FDWLRQV
‡
Only one photovoltaic module can be connected in the input of the inverter (DO NOT connect batteries or
other sources of power supply).
‡
Adverse environmental condition, such as: sun, rain, snow, wind, too hot or too cold, altitudes, humidity,
etc., can lead to a reduction in performance.

constrained environmental conditions (temperature and humidity).
‡
Using the equipment with safety devices not working or disabled.
‡
Using the equipment or parts of the equipment by connecting it to other machines or
equipment, unless otherwise expressed.
‡
Cleaning with corrosive products that may corrode parts of the equipment or with products
that might generate electrostatic charges.
CAUTION!
Risk of electric shock.
Refer servicing to qualified service personnel. Risk of electric shock. Both AC and DC
voltage sources are terminated inside this equipment. Each circuit must be individually
disconnected and the service person must wait 5 minutes before servicing.Risk of
electric shock from energy stored in capacitors. When the photovoltaic array is
exposed to light, it supplies a DC voltage to this equipment.
Do not remove the cover. No user serviceable parts inside.
CAUTION!
Hot surfaces.
To reduce the risk of burns.
Do not touch.
WARNING!
Integral DC Ground Fault Detector/Interrupter
Protection is assembled. Electric shock hazard.
Normally grounded conductors of the
photovoltaic power system may be ungrounded
and energized when a ground fault is indicated.
