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 (70

o

C).

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.
