1. Introduction and Safety
1. INTRODUCTION
& SAFETY
CAUTION
All electrical installations should be done in accordance with local electrical•
codes and the National Electrical Code (NEC), ANSI/NFPA 70.
Before connecting the inverter to the electrical utility grid, your utility•
company must grant approval. Only qualified electricians should make the
connection.
When exposed to light, photovoltaic (PV) arrays create electrical energy that•
could cause a hazardous condition. To avoid this, completely cover the surface
of all PV arrays with opaque (dark) material before wiring them.
The inverter contains no user-serviceable parts. Refer maintenance to qualified•
service personnel.
Do not touch the heat sink located at the top of the inverter, temperatures can•
exceed 158°F (70oC).
!
The PV Powered Grid Tied Residential Inverters 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 Inverters.
1.1 General Safety
IMPORTANT SAFETY INSTRUCTIONS: This product has been engineered and manu-
factured to ensure your personal safety. Improper use may result in potential electrical
shock or burns. Read and follow all instructions for installation, use and servicing of
this product. Read all safety warnings before installing or operating the inverter.
NOTE: A locking tab has been designed into Grid Tied Residential Inverters
It is the sole responsibility of the end user to provide a locking
mechanism that utilizes the tab and secures the cover on the
inverter.
SAVE THESE INSTRUCTIONS: This manual contains important instructions
for the Grid Tied Residential Inverters that must be followed during installation
and maintenance of the Grid Tied Residential Inverters.
2
CAUTION
Read all safety warnings and instructions before installing or operating the inverter.
!
1.2 FCC Compliance
The Grid Tied Residential Inverters have been tested and found to pass FCC Class B
radio interference standards with proper installation of the inverter. This is not a guarantee
that there will be no interference at every installation. If you notice interference at your
installation, try the following potential solutions:
Move or re-orient the affected device.•
Increase the distance between the devices.•
Connect the device to a different AC circuit.•

2. PLANNING
2. Planning
2.1 Select 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 expo-•
sure to sunlight (i.e. not on the south facing side of the building).
The heat sink temperatures can exceed 158°F (70• oC). 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 (-25oC to 40oC).
Location and Clearances
The following clearances are recommend for proper placement of the inverter:
A minimum of 36 inches between the bottom of the inverter box and the•
ground.
A minimum of 12 inches 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.
