SECTION 1.0 Introduction and Purpose
The purpose of this manual is to describe the proper installation, operation, maintenance,
and troubleshooting of the Ideal Power (“IPWR”) SunDial™ 30PV 30kW 3-Phase
Commercial String Inverter, as well as the SunDial™Plus 30PV+S: 30kW 3-Phase
Commercial PV Inverter with Energy Storage.
The SunDial™includes an integrated PV Combiner and DC Disconnect, and is
available in the following product configurations:
•30PV: PV String Inverter with ground-referenced 6-String Combiner.
•30PVF: 30kW 3-Phase PV String Inverter with floating 6-String Combiner.
•30PV+S: 30kW 3-Phase PV String Inverter with grounded-referenced 6-String
Combiner, and factory installed energy storage port
•30PVF+S: 30kW 3-Phase PV String Inverter with floating 6-String Combiner, and
factory installed energy storage port
•+S Kit: a field upgrade kit. Will detailed in a separate installation document.

Product Models: 30PV; 30PVF; 30PV+S; 30PVF+S
MAN-00117, Rev C Page 5of 31
The SunDial™Series utilizes a novel Link Transformer coupled with IPWR’s patented
Power Packet Switching Architecture (“PPSA”) to deliver full galvanic isolation between
the AC grid and the PV Array. This isolation also delivers versatility PV Array wiring
options; both floating and ground-referenced unipolar PV Array are supported. Select
the appropriate Combiner model (floating or grounded), to support your specific
application.
The power ports for the SunDial™ Series include:
•AC1: 3-Wire, 3-Phase unidirectional AC power output port.
•DC2: DC port dedicated to PV Arrays.
•DC3 (+S systems only): an auxiliary DC port dedicated to battery energy storage
systems.

SECTION 2.0 IMPORTANT SAFETY INSTRUCTIONS
Inverter models covered in this manual: 30PV; 30PVF; 30VPV +S; 30PVF+S.
SAVE THESE INSTRUCTIONS
This manual contains important instructions for the Ideal Power 30PV; 30PVF; 30PV
+S; 30PVF+S PV Inverters. All wiring must be in accordance with the National Electric
Code ANSI/NFPA 70.
The following safety notices are used in this manual:
Danger - Procedures or situations that require action to prevent personal
injury or damage to equipment.
Warning - Indicates a potentially hazardous situation that, if not avoided,
can result in serious injury or death.
Important information: Includes key information for the operation of this
equipment or specific instructions to maintain the warranty.
Safety Instructions: All Installations
Danger - This product includes Ground Fault Detection for both grounded and
ungrounded operation of PV systems. All instructions regarding the configuration of this
device must be followed. Failure to follow may result in injury, death, or damage to
equipment. All GFDI related information will be marked with the symbol below:
Danger –To avoid an electric shock, verify that the Inverter’s external AC and DC
Disconnects are open (off). A minimum wait time of five (5) minutes is required after

Installation & Operations Manual SunDial™ Series PV Inverter

MAN-00117, Rev C Page 7of 31
opening AC and DC Disconnects to assure that the Inverter’s internal capacitors have
discharged to zero voltage before performing any work on the Inverter. Utilize lockout
procedures to insure that both AC and DC Disconnects remain in the off position during
all service periods.
Warning –This photovoltaic rapid shutdown equipment (RSE) does not perform all of
the functions of a rapid shutdown system (RSS). This RSE must be installed with other
equipment to form a complete RSS that meets the requirements of NEC (NFPA 70)
section 690.12 for controlled conductors outside the array. Other equipment installed in
or on this PV system may adversely affect the operation of the PVRSS. It is the
responsibility of the installer to ensure that the completed PV system meets the rapid
shut down functional requirements. This equipment must be installed according to the
manufacturer’s installation instructions.
Safety Instructions: Battery Installations
Danger –The Inverter enclosure contains exposed high voltage conductors. The
enclosure’s front access and Combiner doors must remain closed, except during
installation, commissioning, or maintenance by trained service personnel. Do not open
or remove either door if extreme moisture is present (rain, snow, or heavy dew).
Danger –To avoid an electric shock, verify that the Inverter’s external AC and DC
Disconnects are open (off). A minimum wait time of five (5) minutes is required after
opening AC and DC Disconnects to assure that the Inverter’s internal capacitors have
discharged to zero voltage before performing any work on the Inverter. Utilize lockout
procedures to insure that both AC and DC Disconnects remain in the off position during
all service periods.
Warning –These instructions DO NOT contain any information on the operation of
battery systems outside of this product. Refer the manufacturer for the battery system
for installation and servicing instructions.

Safety Instructions: Additional
Danger –The Inverter enclosure contains exposed high voltage conductors. The
enclosure front access and Combiner doors must remain closed, except during
installation, commissioning, or maintenance by trained service personnel. Do not open
or remove either door if extreme moisture is present (rain, snow, or heavy dew).
Danger –Ensure that the equipment is adequately installed and grounded per this
manual and all applicable codes.
Danger –Do not leave foreign objects in the Inverter enclosure. Keep the area around
the enclosure clear of trash, debris, and other combustible materials.
Warning –Personnel Qualification: Inspections and operations requiring access to
lethal AC or DC voltages, should only be performed by qualified personnel.
Warning –All field wiring must conform to the codes set forth in the National Electric
Code ANSI/NFPA 70.
Warning –A separate AC and a separate DC disconnect must be installed with this
system.
Warning –Electrostatic Discharge (ESD) Damage: The Inverter contains ESD-
sensitive equipment. Failure to use ESD control measures while servicing the
equipment may result in component damage and void the warranty.
Warning –Service and maintain the Inverter in accordance with applicable Ideal Power
procedures. Discontinue Inverter use until all equipment defects and safety hazard have
been cured. Replace damaged warning and precautionary labels.
Safety Instructions: Handling
Warning –The SunDial™Inverter, with combiner, weighs approximately 150 pounds. It
is designed to be transported and wall-mounted by two people, without the use of lift or
power equipment. If lift or power equipment is used to move, or lift the Inverter, follow all
safety rules. Failure to do so could result in personal injury or equipment damage.

Integrated Safety Features
The 30PV; 30PVF; 30PV+S; and the 30PVF+S incorporate the following safety
features:
Table 1: Inverter Safety Features
Feature
Action
Hinged Front and
Combiner Doors
Prevents access to hazardous AC and DC voltages and
protects internal circuitry.
Integrated fused 6-
string Combiner with
lockable DC
Disconnect
Prevents access to hazardous DC voltages and protects
internal circuitry. Fuses protect field PV wiring.
DC Ground Fault
Detection
Takes Inverter off-line when DC input ground fault is
detected on either the DC2 or DC3 Ports. Both GFDI
(ground referenced connection) and IMI (floating
connection) are supported.
DC Overcurrent and
Overvoltage Detection.
The Inverter will shut down immediately if DC input
voltages or currents are out of range.
PV Arc-Fault Detection
Both versions of the PV Combiner incorporate an integral
Arc-fault detection. The Inverter will shut down
immediately if such a fault is detected. This will require a
site visit to reset the Inverter.
AC Overcurrent and
over/under Voltage
Detection.
The Inverter will shut down immediately if AC input
voltages or currents are out of range.
AC Frequency Out of
Range
The Inverter will shut down immediately if the grid
frequency is out of range.
Anti-islanding
protection
The Inverter will shut down immediately after detecting
any of the AC faults described above. A five (5) minute
restart timer is implemented on all grid-fault events.
