Read all of the instructions, cautions, and warnings for the Solectria
PVI inverter and associated PV array documentation.
Installation and commissioning must be performed by a licensed
electrician in accordance with local, state, and National Electrical
Code ANSI/NFPA 70 requirements. Use 90°C (194 °F) copper solid
or stranded wire only for all DC and AC wiring to the PVI inverter
to optimimize system efciency. Size conductors per NEC require-
ments.
PV solar arrays produce hazardous voltages and currents when
exposed to light which can create an electrical shock hazard. Use
dark opaque sheets to cover the PV solar array before wiring or
connecting cable terminations.
Before connecting the Solectria PVI inverter to the AC distribution
grid, approval must be received by the appropriate local utility as
required by national and state interconnection regulations, and must
be connected only by qualied personnel.
Do not attempt to open or repair the inverter. The inverter is factory
sealed to maintain its NEMA 4 / IP65 rating. Breaking the seal will
void the inverter warranty.
The AC output circuits are isolated from the enclosure. When
required, providing PV system grounding electrode conductor (GEC)
is the responsibility of the installer. See NEC 690.41. 690.42, and
690.43.
