570-1002542-05B Safety and Product Compliance Guidelines 1‑7

Advanced Energy

Grounding Requirements

Determine the appropriate grounding method with the responsible authority having jurisdiction.

System grounding, if required by Section 250 of the National Electrical Code,

• ANSI/NFPA 70, is the responsibility of the installer.

• The photovoltaic system grounding shall be installed per the requirements of Section 690.41 through 690.47 of the National Electrical Code, ANSI/NFPA 70, and is the responsibility of the installer.

GROUNDING THE PV MODULES

• The PV frames require an equipment grounding conductor per NEC requirements.

• The inverter is a transformerless inverter. For this reason, it has no galvanic isolation. Neither the (+) pole nor the (–) pole of the modules connected to the inverter can be grounded. Only the array frame/racking and modules frame must be grounded, or only the PV module frame and racking must be grounded.

• Insulation resistance detection (ground fault detection): Since the inverter is connected to ungrounded PV arrays, it has an insulation resistance detection circuit that measures the DC insulation resistance between the PV array inputs and earth ground prior starting.

• An Isolation Monitor Interrupter (IMI) is used to limit ground fault and backfeed current to the array and the protective earth connection. This device limits shock hazards by restricting the ability of the unit to connect to the grid when the system exceeds the limits stated in UL1741. Additionally, the PV array Isolation Monitor Interrupter monitors for ground fault current as required by UL1741. If a ground fault occurs, the inverter will disconnect and will not restart until the fault has been cleared.

GROUNDING THE INVERTER

The grounding is provided to assure optimum overvoltage protection. The gauge of the Equipment Grounding Conductor (EGC) must be sized in accordance with Table

250.122 of the NEC.

A GND stud bolt is available in the connection box below the grid connection.

GROUNDING THE AC CIRCUIT

A Protective Earth (PE) feed-through terminal block is available in the AC connection area. The gauge of the AC grounding conductor must be sized in accordance with Table 250.122 of the NEC.

• Establish a ground connection at one of the GND marked terminals before connecting to the grid.

DC FUSES

The inverter uses string fuses to protect the solar modules. A decisive factor for fuse protection of solar modules is the maximum short-circuit current of the respective solar module. The inverter comes standard with 15 A fuses. 20 A fuses are the maximum allowed. Refer to NEC 690 for fuse sizing.

4‑18 Installing 570-1002542-05B

Advanced Energy® AE 3TL Inverters

☞ Important

The size of the string fuses must not exceed the series fuse rating of the PV module. For example, if 15 A is specified on the data sheet of the PV module, this is the recommended fuse rating. If the data sheet does not contain specifications for the series fuse rating, contact the PV module manufacturer.

If a string fuse with a lower trip value is used, the rated fuse current is lower than the short circuit current of the solar module. In this scenario, when there is an increased irradiation situation, the irradiation could cause the panel(s) to produce more current than normal and blow the fuse.

CONNECTING TO THE DC INPUT TERMINALS

DANGER:

Make sure the PV array polarity and voltage between the positive and negative cables are correct before connecting the PV array cables to the DC terminal block.

DANGER:

Assurez-vous que la polarité et le voltage des câbles positifs et négatifs des piles PV sont corrects avant de brancher les câbles des piles PV aux bornes CC.

Data Monitoring and Controls

DATA COMMUNICATIONS OVERVIEW

The AE 3TL inverter is equipped with integrated data monitoring hardware for accessing inverter data. The KP board provides communication access to inverter performance data using the following methods:

AESiteLink using REFUlog: Inverter direct monitoring using the AE web-

• based monitoring solution

• Third party monitoring: USS protocol is translated to Modbus via an external Obvius gateway (optional).

PREPARING FOR INVERTER MONITORING

Internet service must be set up at the installation site before the inverter can be accessed online. An Ethernet connection can be used to connect to the Internet and enable the free AE, web-based inverter direct monitoring, or to a local Modbus/TCP network for third party monitoring.

The data monitoring module supports only hard-wired CAT5 solutions to the inverter. Wireless options external to the inverter are another solution. To access the data monitoring information, customers need to provide a broadband Ethernet connection to the inverter, based on the following specifications:

• Provide a static IP assignment or reserved DHCP that must be configured at the router. A specific IP address must be loaded into the inverter. This can be cable Internet, a DSL line, or equivalent.

• Provide a hard-wired Ethernet connection between the user interface PCB in the inverter and the closest site LAN connection.

• Power cycle the inverter to allow the inverter to communicate via Ethernet TCP/IP as well as a gateway out to the Internet.

If multiple inverters are commissioned to a single site, an Ethernet hub can be located in an outdoor-rated enclosure to distribute the LAN to the inverters.

☞ Important

The data monitoring module does not support dial-up modem connectivity.

☞ Important

Some complex networks may require a system administrator to add the inverter to the network, or to configure the unit to a static IP address.

570-1002542-05B Data Monitoring and Controls 6‑1

Advanced Energy

All AE commercial inverters come standard with an Ethernet port that is intended to be connected to the Internet or to a local area network. Communication is one way – the inverter only communicates externally to the AE cloud hosted servers.

Ethernet Network Layout

AE offers a robust, direct web-based monitoring solution for the AE 3TL that allows you to remotely monitor the performance of your installation. The following figure is an example of the network layout for this type of installation.

Figure 6‑1. Ethernet network layout

To utilize this monitoring service, the following installation steps must occur:

• Inverter must be installed and wired to the customer's local area network (LAN).

• Inverter must be assigned an IP address and be able to communicate to an outside network.

• An online account must be created. This is an automated process that can be completed by visiting the www.refulog.com website.

6‑2 Data Monitoring and Controls 570-1002542-05B

RS-485 NETWORK LAYOUT

When multiple inverters or other Modbus slave devices are connected to a single Modbus master device, the multiple devices need to be connected in a daisy chain layout.

☞ Important

When multiple devices are wired to the network, the network shield must be terminated to earth ground at one point on the network, typically at the beginning or the end. For device connections, the shield must be rewired to provide a continuous shield and isolated from ground.

The inverter provides four LEDs and a display that are the primary indicators of the system status.

When the FAULT LED is on:

Record the message on the display.

2. Turn the DC disconnect switch to the OFF position.

REVERSE CURRENT

The inverter is equipped with string fuses at both positive and negative terminals, DC1 and DC2, to ensure that no dangerous reverse currents can occur in the event of a short circuit.

Reverse currents are fault currents that only occur in PV systems that consist of strings connected in parallel. Short circuits in individual modules or in cells of a module, or a double ground fault can cause the open-circuit voltage of the affected string to decrease to a degree that the intact strings connected in parallel force a reverse current through the defective string. This can lead to excessive heating and thus harm the string. The reverse current could also cause secondary damage.

To avoid damage to PV systems, appropriate precautions should be taken. There are two possible situations that may create a reverse current:

• String sizing: Fusing is recommended when the PV array is sized such that the total short-circuit currents from the non-faulted strings (n-1), is below the maximum backfeed current for the modules.

• Fault event: A properly designed PV system ensures that reverse current during a fault event does not exceed the harmful limit. Each string should be fused individually using a series of connected fuses. If a fault occurs in this situation, the array string with the fault will separate from the intact string, thus avoiding damage to the string.

Overvoltage Fault

600 SERIES

The inverter has two DC inputs, DC1 and DC2, each of which is limited to 500 V. A relay (combiner) inside the inverter connects the two arrays, in series, upon activation. This doubles the voltage level inside the inverter.

A symmetry controller balances the voltages of the two terminals, positive of DC1 and negative of DC2, so they do not exceed 500 V with respect to ground under any condition. If the controller detects an asymmetry, the controller shuts down the inverter. When the inverter shuts down the relay opens, which connects the arrays back into the parallel configuration, limiting the voltage of any array conductor (with respect to ground) to 500 V.

In the rare instance of a failure of the combiner relay, the two arrays will be left connected in series even with the inverter deactivated. Since the symmetry controller does not operate in this condition, there is the possibility of the voltage of an array terminal to ground exceeding 500 V. The inverter detects this fault condition and displays the message ARRAY OVERVOLTAGE.

Advanced Energy® AE 3TL Inverters

1000 SERIES

The 1000 series is limited to 1000 VDC maximum. If the inverter detects more than 1000 V V with respect to ground, it will shut down. The inverter will display an ARRAY OVERVOLTAGE error.

TO RESOLVE AN OVERVOLTAGE FAULT

If an ARRAY OVERVOLTAGE message is displayed on the screen, complete the following steps:

Turn the DC disconnect switch to the OFF position.

2. Contact AE Solar Energy Technical Support.
