If string sizing is done manually, follow the temperature multiplica-
tion factors given in NEC 690.7 table or the PV module manufactu-
rer specied temperature coefcient to ensure PV string voltage is
less than < 600 V
dc
at minimum design temperature
System wiring voltage losses should be no greater than 2 percent
on DC and AC side for optimal system efciency and performance.

INFORMATIONS!
CAUTION!
PRUDENCE!
Installation and commissioning must be performed by a licensed
electrician in accordance with local, state, and National Electrical
Code ANSI/NFPA 70 requirements.
Input and output circuits of this unit are isolated from the enclosure.
System grounding must be done in accordance with the National
Electrical Code (NEC). Compliance is the responsibility of the
installer.
Establish electrically safe work conditions by ensuring there are no
live voltages present on PV input and AC output circuits and that
all dedicated DC and AC disconnects/breakers are locked out and
tagged. Verify that the inverter‘s DC disconnect and AC disconnect
are in the “OFF” position, before inverter installation.
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 any electrical wiring can be connected to the inverter, the
inverter must be permanently mounted.
Use solid or stranded copper conductors only for AC and DC con-
nections. 6 AWG (16 mm
2
) is the maximum allowed wire size.
Inverter warranty is VOID if the DC input voltage exceeds the
inverter‘s 600 V
dc
maximum.
