User Manual

If the mobile phone is directly connected to the SUN2000, the visible distance between the
SUN2000 and the mobile phone must be less than 3 m when a built-in antenna is used and
less than 50 m when an external antenna is used to ensure the communication quality
between the app and the SUN2000. The distances are for reference only and may vary
with mobile phones and shielding conditions.
 When connecting the SUN2000 to the WLAN over a router, ensure that the mobile phone
and SUN2000 are in the WLAN coverage of the router and the SUN2000 is connected to
the router.

The router supports WLAN (IEEE 802.11 b/g/n, 2.4 GHz) and the WLAN signal reaches
the SUN2000.

The WPA, WPA2, or WPA/WPA2 encryption mode is recommended for routers.
Enterprise-level encryption is not supported (for example, public hotspots requiring
authentication such as airport WLAN). WEP and WPA TKIP are not recommended
because these two encryption modes have serious security defects. If the access fails in
WEP mode, log in to the router and change the encryption mode of the router to WPA2 or
WPA/WPA2.

 Obtain the initial password for connecting to the solar inverter WLAN from the label on the side of
the solar inverter.
 Use the initial password upon first power-on and change it immediately after login. To ensure
account security, change the password periodically and keep the new password in mind. Not
changing the initial password may cause password disclosure. A password left unchanged for a long
period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these
cases, the user is liable for any loss caused to the PV plant.
 When you access the Device Commissioning screen of the SUN2000 for the first time, you need to
manually set the login password because the SUN2000 does not have an initial login password.
