Setup Guide:

  • BUILT-IN WIFI .Depending on which model you have, the inverter may have built in wi-fi.  If the inverter is within range of the modem, this is a good wireless option .
  • ETHERNET HARD WIRE.  This is always the best option if it can be done cleanly.  Nothing is more reliable than a hard-wired connection. Multiple inverters can be daisy chained to each other to reduce wiring.  Sometimes the modem is far from the inverter, and makes hard-wiring more difficult, which can make a wireless option preferable.
  • ETHERNET BRIDGE. If the inverter is a long distance from the modem or cannot be hard-wired, using a long range ethernet bridge or repeater is a good solution.
  • VONETS WIFI DONGLE.  This option basically mimics the device having it’s own built in WLAN, by installing a wifi dongle, but requires some setup.

Prerequisite #1: “Commissioning Device” = Phone/ Laptop with wireless wifi capability

Prerequisite #2:  Home internet username/password to log in.

Prerequisite #3:  Inverter with built-in wifi capability.

Prerequisite #4:  Drill with Torx bit to open up the inverter cover.

⦁ Choose a device that has wi-fi internet capability to commission your system monitoring (laptop, phone).

⦁ Connect directly to your inverter’s wifi hotspot (the password will be on the side of the inverter label).

SMA Built In Wifi

⦁ Open a browser window and enter the SMA Inverter Integrated WLAN IP address: 192.168.12.3.  This IP address is assigned by SMA and does not change.

⦁  Once you log into the inverter, first set a user/installer password and then follow the instructions in the setup wizard to connect the inverter to the home internet.

⦁ The customer may need to set up a wi-fi range extender if the inverter is out of range, in which case you will follow the Ethernet Bridge setup instructions.

 

Prerequisite #1: “Commissioning Device” = Phone/ Laptop with wireless wifi capability

Prerequisite #2:  Home internet username/password to log in.

Prerequisite #3:  Ethernet cable long enough to connect inverters & internet modem

Prerequisite #4:  Drill with Torx bit to open up the inverter cover.

  • Plug your “Home Run” ethernet cable into Port A of Inverter 1. 
  • The Home Run ethernet cable is the one that runs from Port A on inverter 1 all the way back to your Internet Modem.
  • You can daisy-chain multiple inverters together: Use another ethernet cable to connect Port B of inverter 1 to Port A of Inverter 2, and so on until all inverters are connected. 
  • Once the hard wire is complete, the home internet network will assign an IP to the inverter within ~15 minutes. 
  • Once the connection is made, you can tap through the screen on the inverter to find the page that lists the “E-IP”.
  • You can rotate through the pages on the inverter screen by tapping the inverter.
  • The IP will look like this:  “168.254.0.xxx”.
  • Grab your commissioning device (laptop/phone) that has internet access.
  • On your commissioning device, connect to the same home internet network that the inverter is connected to.
  • Enter the inverter’s assigned IP address into your web browser.
  • Set a user/installer password (save this somewhere) and then begin following the steps of the SMA Setup Wizard. 

Prerequisite #1: “Commissioning Device” = Phone/ Laptop with wireless wifi capability

Prerequisite #2:  Home internet username/password to log in.

Prerequisite #3:  Ethernet cable long enough to connect multiple inverters to each other.

Prerequisite #4:  Drill with Torx bit to open up the inverter cover.

Prerequisite #5:  Long range Ethernet Bridge device with two units, a “Master” unit & a “Slave” unit.

  • The purpose of an ethernet bridge is to mimic a hard-wired connection, by having two long range devices communicate with each other on either side of the connection, forming a “bridge”.
  • You should have two devices in the ethernet bridge, one is the Master unit connected to the Internet Modem, and one is the Slave unit connected to the Inverter.
  • Plug your Ethernet Bridge (slave) into Port A of Inverter 1. 
  • Plug your Ethernet Bridge (master) into your home Internet Modem.
  • You can daisy-chain multiple inverters together: Use an ethernet cable to connect Port B of inverter 1 to Port A of Inverter 2, and so on until all inverters are connected. 
  • Once the bridge connection is complete, the home internet network will assign an IP to the inverter within ~15 minutes. 
  • Once the connection is made, you can tap through the screen on the inverter to find the page that lists the “E-IP”.
  • You can rotate through the pages on the inverter screen by tapping the inverter.
  • The IP will look like this:  “168.254.0.xxx”.
  • Grab your commissioning device (laptop/phone) that has internet access.
  • On your commissioning device, connect to the same home internet network that the inverter is connected to.
  • Enter the inverter’s assigned IP address into your web browser.
  • Set a user/installer password (save this somewhere) and then begin following the steps of the SMA Setup Wizard. 

Prerequisite #1: “Commissioning Device” = Phone/ Laptop with wireless wifi capability

Prerequisite #2:  Home internet username/password to log in.

Prerequisite #3:  Ethernet cable long enough to connect multiple inverters to each other.

Prerequisite #4:  Drill with Torx bit to open up the inverter cover.

Prerequisite #5:  VONETS Wifi Dongle device.

Unscrew the bottom panel of the inverter

⦁ Unplug the inverter screen, place it somewhere safe

⦁ Plug in the Wi-Fi bridge power cord into the inverter power port. 

⦁ Plug the VONETS Wifi Dongle’s Ethernet cable into the Inverter’s Ethernet A port.

⦁ Click/Hold the button on the VONETS Wifi Dongle and turn it on/reset it

⦁ Scan for available internet networks on your “Commissioning Device” and connect to the VONETS network once it appears.

⦁ Open the internet browser, and navigate to 192.168.254.254.

⦁ Login with default username/password: admin/admin

⦁ Follow the prompts in the setup guide to scan for available hotspots, find the home network that you want the inverter to be connected to.

⦁ Select the Home Wifi, enter the wifi password, and click “Proceed to Connect.”

⦁ When prompted, you may choose to disable “hotspot”, so that the dongle doesn’t show up on nearby devices as an available hotspot network that anyone can connect to.  It may make it more difficult to troubleshoot later on though if you cannot discover the network anymore.

⦁ Wait up to ~15 mins for the assignment of new IP.

⦁ Plug the screen back in, and screw the cover back onto the inverter

⦁ If it doesn’t assign a new IP after 15 minutes, it may help to reset the inverter

⦁ The new IP will look like “168.254.0.xxx”

Note: Sometimes you have to try to get through the VONETS wizard multiple times if the signal is weak, it can lose connection and then you have to refresh the page and start over.

Prerequisite #1: Inverter is already connected to the internet.

Prerequisite #2: Have your commissioning device handy (phone/laptop) with wifi access.

SMA WIZARD

⦁ Connect to the same internet network on the commissioning device that the inverter is connected to.

⦁ Open an internet browser and navigate to the inverter’s IP address – The inverter will display it’s “E-IP” on the screen. You can scroll through the inverter screens by tapping the cover.

⦁ SMA wizard will open up, prompt you to assign USER and INSTALLER passwords.  Save these somewhere you won’t lose them.

⦁ If the inverter has already been assigned a password, you can call SMA for the manufacturer’s default password, if you provide them the serial number on the side.

⦁ Follow the prompts on the wizard – most options are left to the default settings, except for the following:

⦁ Set the correct timezone

⦁ Set rapid shutdown to “other” and then choose “TIGO”, if the system uses Tigo Optimizers.  Otherwise, leave it as default.

⦁ Ensure string failure detection activation is ON.

⦁ Everything else can be default settings, just hit NEXT

Note: Once the wizard is complete, it will take you to a final page where the inverter’s current production is showing. Now you are done with the setup and can move on to adding the inverter to the SMA EnnexOS sunny portal online monitoring portal.

⦁ Log into your Sunnyportal Ennexos installer account.

⦁ Navigate to “Configuration” in the options on the left side

⦁ Choose the option to “Create new system”

⦁ Follow the prompts to set up the customer’s site.

⦁ Title Site “Customer Name – Customer Address”

⦁ Enter the customer’s address.

⦁ When prompted, add the customer’s email to add them to the monitoring.

⦁ Type in PIC/RID (Written on the Inverter’s side label) to help SMA identify which serial # is on site.

⦁ Skip adding PV modules

⦁ Once the site is created, add any additional inverters by logging into EnnexOS going to options on the left-hand side, and navigating to “configuration” -> “device administration” -> add SMA inverter, -> repeat step 5.
