Page 5: Section 1.0 Introduction
This Quick Start Guide describes the features and capabilities of the Stabiliti™ 30C3 Multiport Power Conversion System (“PCS” or “Converter”), as well as the Stabiliti™ 30C Dual Port PCS. It should be used in conjunction with other product documentation provided by Ideal Power (“IPWR”), which are referenced throughout this Quick Start Guide. -
Page 6: Unpacking And Inspecting The Pcs
The Stabiliti is pallet shipped, and is enclosed in a purpose-built heavy-duty cardboard box. Once unpacked, inspect the PCS for any obvious shipping damage. Immediately contact your shipper and Ideal Power regarding any damage noted. Mounting the PCS The PCS, when installed on its wall mounting bracket weighs approximately 135 pounds. -
Page 7: Figure 1: Control Board Low-Voltage Connectors
Figure 1: Control Board Low-Voltage Connectors Shown in Figure 1, there are nine (9) low-voltage interfaces on the Control Board. From top to bottom in ascending order: 1. AC Disconnect (J8) 2. E-Stop / Aux 24 V In (J9) 3. RS485 (J10) 4. -
Page 8: Interface Overview
Interface Overview #1 - AC Disconnect 2-Pin Phoenix-style connector Pin 1 is relay “in” Pin 2 is relay “out” This low-power relay driver output will open whenever the PCS senses a grid-fault condition. It is intended to drive an external 24 Vdc relay which in turn drives an external AC contactor/disconnect, to open the connection between the PCS and the grid. - Page 9 run length, number of devices on the Modbus run, type of interconnection cable, and baud rate selected. A maximum of one terminating resistor should be used when the Modbus interface of multiple units are daisy chained together and connected to one master Modbus device. The optional 120 ohm Modbus terminating resistor is frequently not necessary, and may in fact interfere with proper communications operation under some circumstances.
- Page 10 If DHCP is not available, communicate with the PCS via Modbus RTU. FTP (File Transfer Protocol) Ideal Power use only. Supports remote file transfers to/from the PCS. This provides support for collection of data and fault logs, and also for remote firmware updates. FTP uses ports 20 and 21.

Page 11: Section 4.0 High-Voltage Wiring
NOTE: Not for customer use. SECTION 4.0 HIGH-VOLTAGE WIRING Before connecting AC and DC power sources, it is recommended that the user first operate the PCS with only the Aux 24 Vdc power supply connected. Doing so enables access to the Control Board and the various configuration, control, and monitoring features supported by the Stabiliti™... -
Page 12: Ac External Circuit Protection Disconnect
480 Vac, is commonly used for such purposes. In some jurisdictions, this circuit breaker may also be approved for use as a safety disconnect. However, Ideal Power recommends that you confirm specific AC disconnect requirements with your local Authority Having Jurisdiction (“AHJ”). -
Page 13: Dc2 And Dc3 External Circuit Protection Disconnect
DC power ports. A 1000 Vdc rated, 100 A fused PV Disconnect is commonly used for such purposes. However, Ideal Power recommends that you confirm specific DC disconnect and safety requirements with your local Authority Having Jurisdiction (“AHJ”). -
Page 14: Application Specific Register Settings
All Converters are shipped from Ideal Power have AC1, DC2, and DC3 set to the IDLE Control Method (ports asleep), for safety purposes. They cannot transfer power until configured and/or commanded to do so via the Modbus RTU or Modbus TCP interface. -
Page 15: Modbus Register Assignments
All register addresses must be converted to their hexadecimal equivalent by your system controller. Also note that the Control Method register utilizes a hexadecimal data format “0x….”, where 0x0000 indicates the Port Control Method is IDLE, as defined in Table 1.

the Converter within the 16-bit range of 0-65535 for unsigned and -32768 to 32767 for signed values. These scaling factors apply to read only “measurement registers”, as well as read/write “setpoint registers” used to set desired output voltage, current, or power levels. The setpoint registers are generally not utilized in 30C stand-alone applications. -
Page 20: Watchdog Timer
Watchdog Timer IPWR recommends that our watchdog timer function be utilized in all production Converters deployed by your Company. This ensures that if a system controller fault occurs, or a communications failure occurs between your system controller and the Converter, the system will idle itself after watchdog countdown. -
Page 21: Man-00114, Rev D
NET Control Method (0x0001) To move power amoung active ports, one and only one port on the PCS MUST ALWAYS be set to the NET Control Method, allowing that NET port to satisfy all bi-directional power flows demanded by the remaining port(s), which will typically be assigned a power, current, or MPPT Control Method. -

2. Stand-alone voltage-forming mode. This is otherwise described as a “free-standing” microgrid or nanogrid. No interaction with a utility-grid is enabled or allowed. Detailing #1 above (“blink-less” grid interactive voltage-following / voltage-forming) is beyond the scope of this document, and will be detailed in a separate Application Note.

Page 23: Single Battery Power Exchange
Single Battery Power Exchange AC1 = IDLE / DC2 = PWR / DC3 = NET A novel example of DC-to-DC power conversion. This use case uses a single battery wired identically and shared between the DC2 and DC3 ports. The net current measured and multiplied by stack voltage reflects the efficiency of the Converter’s DC-to-DC conversion. -

5. Run for desired time and shut down the AC1 microgrid output by updating register ‘user_stop’ to 1. AC Microgrid – Using Dual Batteries AC1 = FPWR / DC2 = PWR / DC3 = NET This energy flow example uses two batteries. Depending upon DC2’s PWR sign and setpoint, and microgrid load, one or both of the batteries will support the microgrid. -
Page 25: Pv Firming / Demand Management
power is diverted to DC3, charging the battery. Moving from PV to genset and back again is blink-less because the DC3 battery will completely support the microgrid during these Control Method transitions. NOTE: This use case requires additional hardware and related control mechanisms to disconnect the PV array and connect the genset into DC2, notably external DC contactors and an external 3-phase rectifier. -

c. Update register ‘pv_stop_time’ to appropriate stop time window (in minutes). Update Port 3 (DC3) registers. a. Update register ‘p2_control_method’ to 0x0001 for NET method. Start power flow by updating register ‘user_start’ to 1. a. Note if available PV resource is < 15kW, the battery will contribute as necessary to ensure that 15kW is exported to the grid. -

Modbus Tool executable. A Modbus Quick Start Kit, which includes a USB to RS485 Modbus Adapter is also available for purchase. Contact Ideal Power for Quick Start Kit pricing and availability. This Tool does not work with the Modbus TCP is RTU only. - Page 28 2) “IPC_Modbus_Register_Map.csv” 3) “IPC_Modbus_Register_Map.xls” The “IPC_Modbus_Register_Map.csv” file provides the Modbus Tool with register names and formats compatible with your Converter’s firmware release. Copy this file into the IPC Modbus Tool config folder, replacing the previous version with a 2013 date stamp. The Modbus Tool WILL NOT run correctly until this update is complete.
