Chapter 2 Installation Recommendations

2.1. Site requirements for Enecsys micro inverters and monitoring system

The following things are required if the Enecsys Monitoring system is used:

• The customer must have a broadband Internet connection.

• There must be an unused Ethernet port on the customer’s router to connect to the Enecsys Gateway so the Gateway can communicate with the online monitoring system. The information provided by the Enecsys Gateway is used to troubleshoot the installation as it progresses. See “Chapter 4 Using the Enecsys Gateway” on page 12.

• If the roof is made of metal or lined with metal foil, it may be necessary to install one or more repeaters right below it, in a loft or attic, for example. See “Chapter 5 Using Enecsys

Repeaters” on page 21.

• If a repeater or repeaters are necessary, there must be power outlets in the required locations. See “5.2. Using Repeaters” on page 21.

2.2. Install the Enecsys Gateway

At the earliest possible stage during the onsite installation, the installer should connect the

Enecsys Gateway to the customer’s router using the Ethernet cable provided. When the Gateway is powered up, it will be ready to start monitoring the micro inverters as soon as they are connected to the PV panels on an individual basis. (See “3 Installing the Gateway”.)

Q: Why is it recommended to set up the Gateway as early as possible during the installation?

A: Once the Gateway is functioning it will show which individual inverters have DC connections, even without AC power to the inverters. Solving connection issues before

.

2.3. Plan the cabling layout

The installer must follow the installation design for module layout. Trunk cabling comes in portrait and landscape spacing and the system includes a variety of to accommodate needs.

2.4. Lay out AC cabling; test, then connect to Point of Common Connection

All connections and terminations must be completed per the install la ti on design. See “6.2.

Installing and connecting the AC bus cabling” on page 28.

When all of the AC cabling is in place, but before it is connected to the point of common connection (POCC), it must be inspected and tested to verify proper connection and compliance with the relevant electrical installation standards.

!

WARNING

Connection of the AC cable to the mains utility grid must only be done by

personnel.

NNN-NNN r001 Enecsys

2.5. Connect the AC Cabling to the AC Module

See “6.2. Installing and connecting the AC bus cabling” on page 24.

2.6. Confirm communications between micro inverters and Gateway

By looking at the screen on the Gateway unit, the installer can see if the Gateway is receiving a good signal from all of the micro inverters. See “4.1. Enecsys Gateway Setup” on page

12.

If communications have not been established, it may be necessary to install one or more repeaters. See ”Chapter 5 Using Enecsys Repeaters” on page 21.

2.7. Set up the new installation on the Monitoring website

• If the installer has not worked with Enecsys micro inverters before, it’s time to set up an

Installer Account. For setup details, see section “7.1. Installer login for Enecsys Monitoring

System” on page 30.

• Before installing the gateway, the installer should log onto the Monitoring website with the installer account and set up the individual installation. The installer will need details such as the homeowner’s name and email address, street address of site, estimated yearly energy production, and average cost of electricity per kilowatt-hour.

Chapter 5 Using Enecsys Repeaters

The Enecsys gateway receives signals from the micro inverters on the roof and broadcasts the data over the Internet to the Enecsys Monitoring server. If the gateway cannot receive strong enough signals from micro inverters, a repeater installed nearer the PV modules on the roof will receive the signals, boost them, and then relay them to the gateway.

In some cases it may be necessary to install more than one single repeater to boost signals two or more times before they reach the gateway.

5.1. Failure to establish reliable communications

• If the Enecsys gateway displays the check symbol “ ” on the Default View screen, communications link between the gateway and the inverters is established and is reliable. See

“Figure 20. Enecsys Gateway Default View” on page 23.

• If the gateway does not display the green check symbol, the communications link may not be strong enough to be reliable. It may be necessary to install one or more single repeaters.

See “5.3. Installing one or more single repeaters” on page 21.

5.2. Using Repeaters

• If the “X” symbol is displayed on the gateway Installer Mode communication status, one or more Enecsys single repeaters can be used. Start with one and observe for the “X” to change to a “ ”.

• If the “?” symbol is displayed, signal quality is poor. Distance between the inverters and gateway may be the problem: installing a second single repeater may help.

The diagram shows a building with two single repeaters between the PV modules on the roof and the Enecsys gateway on the ground

6.1. Enecsys micro inverters

Micro inverters are available in various models with various power capacities and DC input

MPPT voltage ranges. Consult the datasheets on Enecsys’s website for most current information. All technical information is subject to change without prior notice.

!

ATTENTION: Retain the Serial Number Stickers

The serial number stickers are used to correlate the position of the inverter and its module to its location in the installation. tion, you will not know where each of the inverters and modules are physically located in the array, which you will need to know for the installation setup. A grid for the stickers is provided: see “Chapter 9 PV module/micro inverter serial number form” on page 40 .

6.2. Installing and connecting the AC bus cabling

Frame-attached micro inverters use the T-cabling system. T-cabling has molded connections that are already and comes with a variety of connectors that sections of cable together and terminate AC branch connections.

6.2.1. T-Cabling System Components

• The T-Cable consists of a continuous length of cable with AC Drop cable connectors spaced at one or two meter intervals.

• T-cables must be cut to the appropriate length for a branch circuit and terminated with a cable end cap.

• Each AC Drop Cable connects to an inverter. Unused drop cable connectors must be covered by permanent weatherproof female caps.

• Field-installable male and female connectors are available to add more cabling options.

WARNING

There must not be any exposed AC connection points. These AC points will be live when the system is connected to the utility grid. Always use the end caps provided to seal the open connection points on the AC drop cables.

WARNING:

Depending on the model used, the maximum number of micro inverters in any AC branch must not exceed the maximum number allowed.

!

ATTENTION

A “protective cap” is not a permanent end cap: It is purely for protecting the inverter connectors during shipping. It should stay on the inverter connector to keep it dry during the installation process. Discard the protective caps only while making the inverter connections. Do not attempt to re-use protective caps.

!

ATTENTION

Do not allow the cable to lie in contact with the roof surface. If necessary, route the cable neatly along the racking using cable clips.

!

ATTENTION

To avoid damaging the inverter or cables, do not force together the AC Drop Cable and inverter AC connectors. The connectors are keyed to prevent misalignment.

• Observe the direction of the drop cable connector: it should have a light-colored triangle-shaped orientation mark. The inverter AC Out connector has the same mark for orientation purposes. See “Figure 27. T-Cable to Inverter AC Connector” on page 33 for details.

• Do not twist the cabling in the process of connection-- tension can damage the cable and connectors over time.

Chapter 7 Monitoring Setup and Installation Launch

7.1. Installer login for Enecsys Monitoring System

• New installers will need to obtain an installer account credential from the OEM.

• Once the account is set up, the new installer should go to the monitoring website: <<URL>>

• Log in, and then click “Go” on the Installer line to log in as an installer.

Figure 25. Choose “Installer” login type

• The view defaults to the LIVE INSTALLATIONS tab. New installers will not see any installations displayed there.

7.2. Adding a new installation

• Fill in the details about the installation on the CUSTOMER, INSTALLATION and SYSTEM pages.

• Click on the ADD NEW INSTALLATION tab to add an installation. Fill in details about the installation on the CUSTOMER, INSTALLATION, and SYSTEM tabs/pages.

Step 1: Input the installation owner’s details.

Setup 2: Enter installation site details.

NNN-NNN r001

• The Installation Name is used to identify the installation site: this name will also be displayed on the installation owner’s monitoring dashboard, so use something customer-viewable.

• Reference Numbers are optional: for example, they can help the installer to cross-reference the installation site to an account number.

Step 3: Input the system information.

• System information describes the PV system: Type, Number of Modules, number of inverters, Mounting system, and Roof Type are entered here.

• “Total cost of system” and “Feed in Tariff” are used to calculate report values.

Step 4: Add gateway serial number(s).

• At this point, you will be entering a serial number for each gateway used. Note that the inverter serial numbers will auto-populate as the installation is

• Note that the user interface says “You will need one gateway for every inverters”: larger installations may use multiple gateways.

Step 5: Begin layout by adding a section.

• Before any sections are created, the screen will appear as below.

• Select the ADD A NEW SECTION button to create a new PV System layout.

Section Details

Q: Why would an installation consist of “sections”?

A: Smaller installations are not as likely to need to be in sections. Larger installations may have areas of different energy production characteristics: different module types, different predicted Annual Energy Production, layout characteristics such as orientation to the sun, or other factors that are recommended to be separately to data collection.

Step 6: Enter section details.

• the default layout grid. The grid can be moved and changed later.

• The system-generated inverter ID will look up entries to prevent errors.

Step 7: Adjust section layout.

NNN-NNN r001

• Double-clicking on the section will allow the user to edit the individual panel details. If the installer wishes to bypass the automatic inverter serial numbers in the setup, the inverter serial numbers can be added manually, panel by panel.

• Adjust, re-size, or reposition the section.

• Double-click section to edit individual PV panels. Use the layout tools to assist with layout design.

• Later, you will assign inverter serial numbers to the PV panels. serial numbers once they are installed and communicating. See “7.2. Adding a new installation” on page 30.

Optional: Manual Adjustments and Serial Numbers

Rather than using the array layout tools and allowing the inverters to automatically report their serial numbers, the installer can manually adjust the panels and enter the inverter serial numbers one-by-one.

• The LAYOUT tab allows the user to manually use the screen controls to access the PV modules in the layout view.

• Select the module, then click the EDIT SELECTED button to add or change panel characteristics. To add more modules, use the ADD NEW button.

• A selected module appears with white “handles”: it can be moved, turned, and stretched as needed.

• The SERIALS tab allows the user to manually load the inverter serial numbers, or to edit numbers that are already there.

• Type the inverter serial in the Search box. Click the ADD TO LIST button to add it to the

Available Serials column. Drag the added number from the column onto the module.

Optional: Saving a pending installation

• After the layout is done, click the SAVE button. This will allow you to pause and return to

the installation later, if necessary.

7.3. Installation finalization and launch

If you have saved an installation layout previously, you can resume the installation and ize it.

Step 1: Find the pending installation.

• Log on to the Enecsys monitoring site with your Installer information. You will be able to return to your saved installation from the previous steps by going to “Pending Installations” tab and selecting it.

NNN-NNN r001

Step 2: Drag-and-drop inverter serial numbers.

• If the gateway serial number has been entered, the array design was set-up previously, and the gateway is communicating correctly, the inverter serial numbers will automatically be reporting on the list of available serial numbers.

Enecsys

• The installer will need to drag each inverter serial number to the appropriate module. Refer to the “PV module / micro inverter serial number form” that was with stickers during the installation for their positions in the array design.

Step 3: Check work and launch installation

• When you are with dragging the available serials to the modules, save and

You will arrive on the PENDING INSTALLATIONS Screen.

• Inspect the information categories for green check marks. If there is an “x” in a column, it button to add the required information.

• After you have set the installation live, click CONFIRM.

• As soon as the physical installation is completed, the inverters start sending messages to the gateway and the new system can be seen on the monitoring website.

Step 4: Inform the customer of new user account.

• Click the NEW USER button for the system to automatically send the installation owner a

User name and Password to access the monitoring account. The customer information the installer used for the owner details will be used to generate the email. See “7.2. Adding a new installation” on page 30 for details.

• Advise the installation owner that the email is coming.

Note: In locations covered by the UK 1998 Data Protection Act (“DPA”), have the DPA form signed by the customer and return it to Enecsys.

• The customer should log in to the Enecsys monitoring website at http://monitor.enecsys.

com using the Username and Password provided in the email. There is also a link to the

“Monitoring System logon” on our company website.

• The customer should in all the screens with their details, and also set their Username and

Password to ones that they can remember.

8.2. Communication

Problem

No illuminated display presented when the Enecsys gateway is powered on.

The Enecsys gateway does not connect to the internet.

The Enecsys gateway shows 0 when the micro inverters are installed.

The Enecsys gateway is not showing the correct number of installed micro inverters.

Solution

Replace the Enecsys gateway.

Check the Ethernet cable and router. Replace the

Enecsys gateway.

Verify that the micro inverters been installed correctly.

Verify the AC connections have been made: the connectors should snap lock together during connection.

Verify that no cabling has become pinched by the PV modules.

If the installation is on a metal roof or on a roof with a metal liner, has a repeater been installed?

Check PV module / micro inverter connections.

Is there sunlight on the modules? (During the night the gateway will always show 0 unless a repeater or double repeater has been installed, in which case the gateway will show 1 or as many repeaters as there are in the installation).

8.3. Monitoring

Problem

The installation cannot be set to “live” on the monitoring site.

All the micro inverters show 0W power.

One, or just a few, micro inverters are showing 0W power.

Cannot log in after installation has been set live by installer and user account created.

Excessive time elapses when downloading monitoring data.

Solution

Check that information on all tabs on the monitoring site have been in correctly and that no red “X”es are present.

Inspect the number showing on the gateway to make sure all the micro inverters are communicating.

Check that the system is properly connected to the utility grid.

Check that there is grid voltage from the AC cable on the roof.

Inspect the number showing on the gateway to make sure the inverters are communicating.
