Product Models: 30PV; 30PVF; 30PV+S; 30PVF+S
MAN-00117, Rev C Page 10 of 31
Ground Fault Detection –Ground Referenced PV Combiner (30PV / 30PV+S)
For ground referenced PV array connections, the negative leg of DC2 (PV) and the
negative leg of DC3 (Battery: +S systems only) are electrically common and referenced
to earth ground through a shared 1 A GFDI fuse to detect ground fault conditions. If
such conditions are detected, the Inverter is automatically taken off-line. The Inverter
will not attempt to restart until the fault condition is cleared, and AC Power is cycled.
If the ground fault detection fuse shared between DC2 and DC3 is blown as a result of a
fault event, it must be replaced in order for the Inverter to attempt restart. Faults are
indicated on the Front Panel Display, and are also available via the Modbus RTU or
Modbus TCP communication interfaces.
Ground Fault Detection –Floating PV Combiner (30PVF / 30PVF+S)
Floating PV Arrays and Batteries (+S option only) utilize an onboard “IMI” ground fault
detection scheme. This enables the Inverter to measure the conductors of the DC
Power source. If leakage to ground is present past the limits set in UL 1741 then the
unit will fault and prevent operation until the fault is cleared from the DC source(s).
Note that the negative legs of DC2 (PV Array) and DC3 (Battery: +S option only) are
electrically common, but remain floating, relative to earth ground.
•In the event of an “IMI” fault, the fault can only be cleared by cycling AC power to
the unit.
DC Over/Under Voltage Fault Detection
The Inverter also has DC over-voltage (default is 1000 Vdc) and DC under-voltage
(default is 100 Vdc) detection circuitry. If these limits are exceeded the Inverter will shut
down, or if commanded to make power, will not start. These default limits are easily
changed via the Modbus interface; however, they cannot be programmed above the
1000 Vdc factory maximum.
AC Current Fault Detection
The output voltage is synchronized to the AC utility line. The Inverter operates as a
current source following the grid voltage waveform (“voltage-following”). Should the
Inverter experience an AC current fault condition, it is automatically taken off line. The
Inverter is shipped from the factory with a default five (5) minute restart countdown
timer.

Product Models: 30PV; 30PVF; 30PV+S; 30PVF+S
MAN-00117, Rev C Page 11 of 31
AC Frequency and Voltage Fault Detection
The quality of the power delivered to the utility line must meet or exceed the
requirements as specified in IEEE 1547a. If the utility frequency or voltage shifts outside
the regulatory specified limits, the Inverter will automatically detect the condition and
shutdown. The Inverter is shipped from the factory with a default five (5) minute restart
counter for AC over/under Frequency limit faults and AC over/under voltage limit faults.

•Note that the negative input for DC2 (T8: DC COM) and the negative input for
DC3 (T9: DC COM: +S option only) are wired together and are electrically
common behind the Filter Chokes installed on DC2 and DC3 (+S option only).
DC Wiring Options
The DC2 Port supports either ground-referenced monopolar, or floating PV connections,
depending upon the Combiner type selected.
•If a floating Combiner is selected, the battery connected to DC3 (30PVF+S only)
MUST also be floating, and cannot be referenced to earth ground.
•If a ground-referenced Combiner is selected, the battery connected to DC3
(30PV+S only) will be ground-referenced,.
•Note that there are configuration jumpers on the DC2/DC3 Interconnect Board.
These jumpers are factory configured to support either the floating, or ground-
referenced Combiner type. Do not disturb or change these connections.
•Note that the floating and ground-referenced Combiners are unique and different
equipment designs. They are not interchangeable.
Combiner Overview
Access to both the enclosure and the Combiner requires a 3 mm Allen Wrench. The
Combiner’s DC Disconnect must be in service position (facing left) to open the Combiner
door. The DC Disconnect is “ON” when facing up or down. For lockout purposes, the DC
Disconnect must face right. The Combiner and enclosure doors are both hinged on the
left side.
Both versions of the Combiner feature three 1-inch conduit fittings located on the
Combiner bottom access panel. The conduit fittings simplify the routing and termination
of AC1 and DC3 (+S option only) power cables, as well as low-voltage control
wiring. Once routed through the Combiner, the AC and DC power is terminated on the
AC1 and DC2/DC3 interconnect boards. Low-voltage control wiring is terminated to the
control board, located on the upper left side of the enclosure. Use the left-most Conduit
fitting, as well as the two cable-guides provided in the enclosure to route and contain low-
voltage wiring.
