1.0 Introduction
The PVI 10KW, PVI 13KW, and PVI 15KW are commercial, three-phase grid-tied PV inverters
designed to be interconnected to the electric utility grid. By following this manual the inverter
can be installed and operated safely. This installation guide is used as a reference for
commissioning and as a guideline on how to use the inverter most effectively.
Feeding power onto 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, three-phase
commercial, industrial, institutional or electrical utility facility’s electrical system which is
connected to the electrical grid.
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 follow local regulations regarding net metering and interconnection in your local
area. Note that some utilities need to change their revenue kWh meter for proper net metering
measurement and billing.
