1 INTRODUCTION
The PV Powered Grid Tied Residential Inverter is a utility interactive inverter for
photovoltaic (PV) systems.
The inverter is tied to an electrical source provided by the local utility company as
well as to the PV system. The inverter contains everything needed to convert the DC
voltage generated by the PV arrays into the AC voltage required to power a house.
This manual provides information necessary for the successful installation and use of
the PV Powered Grid Tied Residential Inverter.
2 INSTALLATION
2.1 Selecting a Location for the Inverter
When choosing a location for the inverter, consider the following criteria:
• The inverter is suitable for both indoor and outdoor installation; the inverter
enclosure has a NEMA 3R rating.
• The optimum location of the inverter is outside, shielded from direct exposure
to sunlight (i.e. not on the south facing side of the building).
• The heat sink temperatures can exceed 158°F (70°C). The inverter must be
installed so that people will not touch the top of the unit.
• The inverter is designed to handle the temperature extremes of most
climates. The operating and non-operating environmental ambient
temperature range is -15°F to 105°F (-25°C to 40°C).
• The following clearances are recommended for proper placement of the
inverter:
• A minimum of 36″ between the bottom of the inverter box and the
ground.
• A minimum of 12” above the heat sink.
• Visibility of the operating LEDs and display located at the top front of
the inverter box should also be considered.
• If the inverter is installed in an enclosed space, adequate ventilation must be
provided.
2.2 Mounting the Inverter
The inverter should be mounted vertically to a flat, solid surface such as wallboard,
concrete, or wood siding. The inverter should be located near the PV arrays to
minimize the DC wire length.
The mounting bracket provided makes mounting the inverter quick and simple. The
2 screw holes at either end of the bracket are 16” apart. Once the wall studs are
located, anchoring the bracket becomes an easy task.
WARNING: Before drilling holes to mount the inverter, verify that there are no
electrical wires or plumbing in the area.
