Setting Up Your EnaSolar Inverter for Wi-Fi Reporting

How to setup an EnaSolar Inverter for Wireless Reporting

Harrisons Energy Solutions use EnaSolar Grid Tied inverters with their solar panel installs, and the great thing about these inverters is that they are Wi-Fi capable! The inverters are able to connect to your home’s Wi-Fi network – however setting it up initially, or after you change routers or Wi-Fi passwords can be a bit tricky, so follow this user guide to get your inverter successfully connected.

Setting up your inverter with Wi-Fi allows you to view your solar system’s power production, and it’s only a three step process to get the inverter connected.

But I’ve already setup my inverter for Wi-Fi, but I can no longer find it or access the reporting?

If you have setup your inverter in the past but you can no longer access the reporting, read the senarios below first.

  1. Your wireless modem/router has been restarted and given your inverter a different IP Address automatically. If your inverter does not say ‘Wi-Fi Access Point Not Found’ then you should beable to find the new IP Address by tapping the inverter until the new IP Address is displayed. Use this new IP address to access the reporting.
  2. Your wireless modem/router has been reset to factory settings and now has a different wireless network name (SSID). If your inverter says ‘Wi-Fi Access Point Not Found’ then you’ll need to setup your inverter again using the ‘first time’ setup instructions below.
  3. You changed Internet Service Provider (ISP) and they gave you a new wireless modem/router. If this is the case the name of your wireless network (SSID) is likely different and your inverter won’t know what it’s called so it will display ‘Wi-Fi Access Point Not Found’. You’ll need to setup your inverter again using the ‘first time’ setup instructions below.

First Time Setup Instructions for Wireless Reporting

Follow the instructions below if you have not setup your inverter for Wi-Fi reporting, or if the senarios above apply.

  1. Connect your PC/Smartphone/Tablet to the inverter:

a. Start by tapping on the inverters front panel to toggle the information screen to get to the Network screen: On the Network screen, the inverter will show a 5 digit key. This is the “Wi-Fi Ad-hoc” connection password (“WEP key”). It should look like this:

b. The inverter is now available for a Wi-Fi “Ad-hoc” connection. Its’ network name will show up as ENASOLAR-GT-0123456789 (where the number “0123456789” is replaced by your inverter’s serial number).

c. Now you need to make your PC/Smartphone/Tablet ready to connect to the inverter. This depends on what computer or device you have:

Microsoft Windows: Go to Control Panel, then select “Network and “Internet” then, then go to “Network and sharing centre” and click on “Connect to a network” and look for available networks.

Android: Go to Settings, Wireless networks, Wi-Fi settings and look for available networks.

iPhone/iPad: Go to Settings, then select “Wi-Fi”

d. Choose the Wi-Fi network called “ENASOLAR-GT-0123456789” and use the 5 digit key from the inverter in step 1a) as the network password.

2. Start the browser on your PC/Smartphone/Tablet:

a. Open your browser (e.g Safari, Google Chrome, or Internet Explorer) on your device and then enter the inverter’s default IP address “http://10.10.5.5” in the browser’s address bar and hit enter to get the inverter’s web page.

b. Once you reach the inverter’s web page, click on the “Settings” part of the menu, then on the “Wireless” link.

c. The page will ask you for a username and password. These are default with your inverter, your username is: Admin and your password is: Admin1 (make sure you use the correct capital letters!)

d. Now type in your Wi-Fi “Network name (SSID)” – You may need to find this on your computer if you don’t have it saved. To find your router’s SSID you just need to check the name of the network you are normally connected to.

e. Choose the type of “Encryption” you use on your Wi-Fi network from the drop down menu

f. If you have chosen Encryption above, then enter your Wi-Fi “Password” – Case sensitive!

g. Finally, click on “Write” at the bottom of that web page.

3. The inverter now takes the settings you entered (your Wi-Fi network name & password) and tries to use them, connecting the inverter to your Wi-Fi router:

a. The inverter drops the Wi-Fi Ad-hoc connection with your PC/Smartphone/Tablet automatically, allowing it to connect to your home’s Wi-Fi network.

b. The inverter then uses the Wi-Fi network name and password that you entered to connect to your Wi-Fi router.

c. When the inverter successfully connects to your Wi-Fi router, the inverter display screen will show a new IP address (it will look like a string of numbers separated by full stops) and the signal strength for the new connection (it must be 30% or above). If it’s not coming up, you may have to tap the inverter front panel to switch between screens to see this message.

d. If these messages don’t come up, the inverter probably failed to connect to your wireless network. If the inverter is unsuccessful in trying to connect, it may be because the signal strength ofyour router is too low as any strength below thirty percent is too weak for the connection. The password or network name for your Wi-Fi network could also have been misspelt. In the case of either of these issues, the inverter will eventually go back to offering the Wi-Fi Ad-hoc 5 digit key on its’ LCD display, and you can try the process again.

Now that the inverter is Wi-Fi connected to your local network (to your Wi-Fi router), you need to connect your device, e.g. your laptop or smartphone, to the same local network. Then check the inverter IP address (a string of numbers separated by full stops e.g. http://192.168.1.105) on the inverter LCD and enter the inverter IP address in the address bar of your browser. Once you’ve done this the inverter web page will come up. Done! Depending on your Wi-Fi router, this IP address may change occasionally, but the current IP address is easily checked by tapping on the inverter front panel.

The inverter is now also connected to the EnaSolar Online service, reporting power production and inverter status to the online database, storing data in the cloud. If your home doesn’t have a Wi-Fi router or Wi-Fi network on the site, but you have a Wi-Fi enabled laptop or smartphone, you could still use that device to check the inverter web page occasionally, by following this User Guide from the beginning and up to step 2a, but not doing step 2b through to 3d. This will give your laptop/smartphone access to the inverter web page via the Ad-hoc connection. However, no inverter production data will be sent up to EnaSolar Online if this Ad-hoc method is used.

Inverter log files can also be downloaded directly from the inverter and saved as a file on your computer, i.e. : http://192.168.1.105/log_daily.htm and http://192.168.1.105/log_minute.htm
