Stranded copper wire should be checked so that all strands go into
the terminal opening.
If a neutral wire connection is required for the grid connection, make
sure the neutral wire is securely connected to the neutral terminal.
Loose neutral wire connection can result in incorrect grid voltage
detection.

Terminate inverter’s AC output wires inside the AC disconnect or junction box.
– Connect the AC equipment GND wire to the PE screw terminal (A) and using a 3/16“ (4
mm) flat blade cabinet screw driver tighten the screw terminal to to 10.5 in-lbs (1.2 Nm)
of torque.
– Connect the “WHITE” Neutral wire to the “N” screw terminal (B), and using a 3/16“ (4
mm) flat blade cabinet screw driver tighten the screw terminal to to 10.5 in-lbs (1.2 Nm)
of torque.
– Connect “RED” L1 wire to the “L1” terminal (D), and using a 3/16“ (4 mm) flat blade cabi-
net screw driver tighten the screw terminal to to 10.5 in-lbs (1.2 Nm) of torque.
– Connect “BLACK” L2 wire to the “L2” terminal (C), and using a 3/16“ (4 mm) flat blade
cabinet screw driver tighten the screw terminal to to 10.5 in-lbs (1.2 Nm) of torque.

Inverter RS485 communication connections
WARNING!
AVERTISSEMENT!
Read all of these instructions, cautions, and warnings for the Solec-
tria PVI inverter and associated PV array documentation.
Interface connection RS485
The Solectria PVI inverters offer an RS485 communication interface which can address up to 16
daisy chained inverters. For optimal performance, all unused interface connections must always
be terminated by placing the termination jumper in the “on” position.
