Ground Requirements
This product is intended to be installed as part of a permanently grounded
electrical system per National Electric Code ANSI/NFPA 70. A copper ground
rod must be installed within three feet of the PV100S enclosure. This is the single
point earth ground for the inverter system. The single point ground for the system
is to be made at the AC ground bus bar (TB2) in the AC Interface Enclosure.
System Neutral Requirements
The PV100S is designed to be installed as a 4-wire system. As required by the
UL 1741 listing, a neutral conductor from the utility-interconnect must be
terminated at TB6 within the AC Interface Enclosure to ensure that the AC
voltage sensing circuit can perform an individual phase voltage (line-to-neutral)
measurement. The function of the neutral connection is to provide a point of
reference for measurement purposes that is essentially at ground potential. No
power will flow through the neutral conductor.
Communication Requirements
The PV100S can accommodate any one of the following options for PC
Communication:
•
POTS Connect Kit
- uses a MultiTech
®
56K Modem, RS232/Fiber Optic
Converter (configured for ethernet) and SA2 Surge Arrestor. A direct analog
phone line to the local phone service is required to use this feature. The phone
line used for PV100S communication cannot be routed through a Private
Branch Exchange (PBX) unless an analog PBX card is used.
•
Wireless Connect
- uses a GSM Wireless Modem.
•
Ethernet LAN Connect
- uses a data communication device to enable the
unit to connect to a local area network.
•
Direct Connect Kit
- uses a RS232/Fiber Optic Converter (configured for a
PC), a DB25-to-DB25 gender changer, and a DB25-to-DB9 Serial Cable.
Determine which communications options are required for the installation and
procure the appropriate service or phone access. The personal computer to be used
with this unit must have the appropriate hardware as well, such as a 56K modem
for dial up connection or a Network Interface Card (NIC) for a LAN connection.
Utility Side Isolation Transformer Requirements
The PV100S is supplied with a custom, high-efficiency, isolation transformer as
part of the AC interface/transformer assembly. The utility side windings of the
isolation transformer are configured Wye and must match the voltage at the utility
inter-tie. The PV100S is a balanced, three-phase, current-sourcing inverter and
only operates with the presence of a stable utility voltage. The transformer is also
supplied with a neutral connection on the utility interconnect. Connection of this
