Inverter Startup Checklist

INVERTER STARTUP CHECKLIST
WARNING:
Maintenance personnel must receive proper training before installing,
troubleshooting, or maintaining high-energy electrical equipment. Potentially
lethal voltages could cause death, serious personal injury, or damage to the
equipment. Ensure that all appropriate safety precautions are taken.
AVERTISSEMENT:
Le personnel d'entretien doit recevoir une formation appropriée avant
d'installer, de dépanner ou d'entretenir un équipement électrique à haute
énergie. Des tensions potentiellement mortelles pourraient provoquer la
mort, des blessures graves ou des dommages à l'équipement. S'assurer que
toutes les consignes de sécurité appropriées ont été respectées.
AC Side
Visually confirm that five (5) conductors are connected to the AC terminal block of
the inverter. The AC terminals used are labelled as L1, L2, L3, N, and GND.
The type of conductor used has the following requirements: 10 AWG to 6 AWG,
copper wire, rated for 90°C.
Perform a pull test on each of the five (5) conductors connected to the AC terminal.
DC Side
600 series only: A separate raceway is used to bring the DC conductors into the
inverter integrated combiner box. Half of the PV array strings are installed in one
raceway, and the other half in a separate raceway.
600 series only: Half of the PV array strings are connected to the DC1 fuse holders
and the other half to the DC2 fuse holders in the connection box. For example, 8
strings total = 4 strings on DC1 and 4 strings on DC2.
Ensure that the positive and negative conductors are connected to the correct DC
terminals as shown in the user manual.
Grounding
The PV array should be ungrounded: A Grounding Electrode Conductor (GEC) is
not present on the DC side.
