PVI13KW Installation and Operation Manual

1 Introduction
The PVI13KW is a commercial, 3-phase grid-tied PV inverter designed to be inter-connected to
the electric utility grid. With this manual the PVI13KW can be installed and operated safely.
This installation guide is used as reference for the commissioning and as a guideline on how to
use the inverter most effectively.
Feeding power into the grid involves conversion of the DC-voltage from the PV-array to grid
compatible AC-voltage by “inverting” DC to AC. This unit feeds power into a standard 208V
AC, 3-phase commercial, industrial or institutional facility’s electrical system which is
connected to the electrical grid. (A 480V AC version is also available.)
If the PV system and inverter are providing the same amount of electrical power that the facility
is using then no power is taken from or fed into the utility grid. If the facility is using more
power than the PV system is providing, then the utility grid provides the balance of power. If the
facility is using less power than the PV system is generating, then the excess is fed into the utility
grid.
Be sure to look into local regulations regarding Net Metering/inter-connection in your local area.
Note that some utilities need to change their revenue kWh meter for proper Net metering
measurement and billing.
