49. Reset your inverter by turning off either the Solar Supply Main Switch located in the Switchboard, or the AC Isolator adjacent/below the inverter. Then turn off the PV Array DC Isolator(s) located adjacent/below the inverter.
50. Wait a couple of minutes before turning on first the DC Isolator(s) then the AC Isolator (in the reverse order to how you turned them off).
51. To access the smart meter information, log on to your account, and after about 10 minutes the format of your account should change. Or, download the Solar.web PRO App from your App Store.


1. You will need to start by connecting the inverter. There are two different ways of doing so, you can either use Wi-Fi (the wireless network) or the Ethernet cable for connection.

a) To connect using Wi-Fi, access the Wi-Fi settings of your devices and detect the Wi-Fi which will be in the format SMA19xxxxxxxx.

b) If you are installing for the first time, then the Wi-Fi password will be SMA12345. The Initial inverter set-up will take place through Installation Assistant and the password will change to the WPA2-PSK password that is written on the label. Also, remember that the initial password will change to the above password after 10 hours of operation, whether or not the set-up has been performed.

2. Once this is connected, you will need to visit your web browser and type the IP in case of WLAN / wireless / Wi-Fi connection and the IP in case of an Ethernet connection.This will direct you to Sunny Boy’s web user interface.
You will need to perform the initial configuration by logging in as Installer and changing the User Group dropdown. It will then ask you to create a password that will be used to register the inverter in their official portal.

3. After logging in, you will have to set up the inverter using the “Installer Assistant”. If the option of configuration does not appear, then the option can be selected from the top right-hand corner of the screen.

4. Next, you will need to synchronize your inverter with the wireless network.

5. Click on the WLAN tab and then search and select the local wireless network to which the inverter is connected.

6. Next, enter the password and click on connect. The next IP address will be assigned to the inverter by the router if DHCP is enabled. The new IP address will then be shown on the configuration page.

7. Then click on Save followed by next.

8. Then do as it is directed on the screen as prompted by the Installation Assistant.


This quick guide describes how to connect a SolarEdge Wi-Fi device to a network:


WPS (Wi-Fi Protected Setup) is a system built into modern broadband routers which allows pairing of devices without the need for a password entry. If the network uses a router with WPS push button security, a separate quick guide is available for homeowners (the procedure is also contained in this document).

If the broadband router does not have this feature, entering the network password is required using the inverter’s internal user buttons.
This requires removing the inverter cover, which is to be performed by a qualified PV engineer as there are dangerous current levels inside the inverter.

The following figures show the inverter connectors and components, located at the bottom of the inverter. The ON/OFF switch and the LCD light button may vary depending on the inverter model: Use the LCD button as follows:
- Short-press (one second) to scroll down to the next menu option
- Long-press (three seconds) to select the item.
- Exit the Setup mode by selecting Exit in each submenu screen or wait for the device to exit Setup mode automatically, if no buttons are pressed for more than two minutes.

Perform these steps after a broadband router change or a password change of the network.

To connect using WPS:

1) Verify that the inverter ON/OFF switch is OFF.
2) Press and hold down the LCD light button for 5 seconds (release before 10 sec have elapsed). When releasing, the main menu is displayed:
3) Scroll down to the Communication submenu and select it. (Some of the menu items may vary depending on device and configuration).
4) Select the Server submenu, scroll down to the Wi-Fi option and select it
5) Scroll down to the Wi-Fi Conf submenu and select it. If Wi-Fi Conf indication appears, the Wi-Fi module is not installed correctly. If your router supports WPS mode, you can automatically connect without entering a password as described in the next steps. If your router does not support WPS mode skip to step 9.
6) Select WPS mode. The status message Waiting is displayed.
7) On your wireless router, locate the WPS button. Push and hold it down until a LED lights up (refer to your router manual).
8) On the inverter LCD, check that the message has changed to Connected.
9) If connected, exit Setup mode. Otherwise, to connect to a specific network from a list, do the following:
    a. Make sure the inverter ON/OFF switch is OFF.
    b. Disconnect the AC to the inverter by turning OFF the circuit breaker or isolator supplying the inverter.

Wait 5 minutes for the capacitors to discharge.

    c. Open the inverter cover’s six Allen screws and carefully pull the cover horizontally before lowering it.
    d. Turn ON the AC to the inverter. WARNING! ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter cover is removed.
    e. Select the following in the LCD menus: Communication è Server è Wi-Fi.
    f. Select: Communication è Wi-Fi Conf. è Scan Networks. Wait until networks are found.
    g. Select the required network from the list of available networks.
    h. If required, enter the security key (up to 20 characters). A short press scrolls round the alphanumeric list. A long press selects the required character and      moves on one space.
    i. When the security key has been entered, long-press the Enter button to accept the password. The system will start the connection process. Connection time may take up to 30sec, after which the message Connected is displayed on the LCD for 5 seconds.
    j. Carefully attach the inverter cover and tighten the six Allen screws with a torque of 9.0 N*m/6.6 lb*ft.
    k. Turn the inverter ON/OFF switch to ON. Your system is now connected to the Wi-Fi network and will resume sending data to your SolarEdge monitoring portal account.
