PVI 10kW / PVI 13kW / PVI 15kW
WARNING: Before making the DC connections at the DC disconnect, check the correct
polarity and admissible DC voltage between the grounded and ungrounded DC
connections.
WARNING: The wiring connections of the inverter to the DC voltage from the PV strings
and the AC voltage of the utility must be done with the AC and DC disconnects off,
building AC source circuit panel / breaker off and the PV module strings disconnected (or
covered with an opaque material). Open DFDI fuse holder before wiring DC connections.
WARNING: A fused, correctly rated PV combiner must be used with this version of the
inverter.
WARNING: Even when in the off position, the DC disconnect will remain live on the PV
side ("line") when the PV modules are in daylight. The inverter ("load") side of the
disconnect will also remain live after the disconnect has been shut off until 60 seconds after
the LEDs turn off, as electrolytic DC bus capacitors in the inverter discharge.
 Connect each of the AC phase conductors and the AC equipment and electrode grounds to the
terminal in the AC disconnect. Phase conductors should land in the "LINE" terminals and ground
conductors should land in the ground bar.
 For the DC wiring without an integrated fused PV combiner, connect the DC conductors from an
external string combiner to the labeled + and – terminals inside the DC disconnect. Connect the DC
grounds to the ground bar.
 For the DC wiring with the optional integrated fused PV combiner, connect the DC conductors
from each string to the labeled + and – terminals inside the DC disconnect. Connect the DC grounds
to the ground bar.
 Measure and verify proper DC voltages and polarity. Measure and verify proper AC voltages and
phase rotation. AC conductors must follow clockwise phase rotation for: L1/A, L2/B and L3/C.
Test with a phase rotation tester or a scope-meter. Extech, Fieldpiece, Fluke, UEi and many others
make phase rotation meters, sometimes referred to as motor rotation meter. Do not assume existing
color code or building wiring is correct! Incorrect phase sequence at the AC connection can damage
the inverter.
WARNING: AC and DC fuses may only be replaced with the following, available through
