Overview of PV100S Installation
Planning Planning for a system requires complete understanding of all the components that
are involved to successfully install the PV100S to meet the required national,
state, and local codes.
Definition A power system (such as the PV100S) is a collection of devices designed to
supply AC power to the utility grid from a solar energy (PV) source.
Components All types of grid-tied inverter installations, residential or industrial, share common
components. This chapter describes each component and suggests the minimum
requirements for a safe installation.
Location The PV100S 100 kW Grid-Tied Photovoltaic Inverter is designed to be installed
in either an indoor or outdoor location. The PV100S must be anchored to a level,
concrete floor or pad.
Ideally the AC interface enclosure/transformer assembly is placed on the left side
of the Main Inverter Enclosure. The AC interface enclosure/transformer assembly
may be co-located adjacent to the left side of the Main Inverter Enclosure up to,
but not exceeding, 15 feet away.
Clearance Adequate ventilation and service access must be taken into consideration when
installing the PV100S. See “Ventilation and Serviceability Requirements” on
page 2–3 for specific clearance requirements and ambient temperature
requirements.
Conduits and
Conductors
Given the flexibility to co-locate the AC interface enclosure/transformer assembly
to fit a desired system layout, the conduits and conductors are to be supplied by
the installer.
See “Conduit Penetration” on page 2–8 for recommendations on enclosure
penetration locations and conduit routing.
See “Conductor and Conduit Sizing” on page 2–11 for information on sizing the
conductors and conduits.
All interconnect wiring and power conductors interfacing to the PV100S must be
in accordance with the National Electric Code ANSI/NFPA 70 and any applicable
local codes.
WARNING: Shock Hazard
Installations of this equipment should only be performed by qualified technicians.
Installers must meet all local and state code requirements for licensing and
training for the installation of Electrical Power Systems with AC and DC voltage
to 600 volts.
