7 Operations on the Local FusionHome App 
7.1 App Overview 
Function 
The local FusionHome app (app for short) is a mobile phone app that locally communicates 
with the SUN2000L over WiFi to allow for querying alarms, configuring parameters, and 
performing routine maintenance, and commissioning. 
Connection Method 
After the DC or AC side of the SUN2000L is energized, the app can connect to the 
SUN2000L in either of the following ways: 
 
Method 1: The mobile phone connects to the SUN2000L directly.

Method 2: The mobile phone connects to the SUN2000L over a router. Do not use this 
method for the first login and ensure that the SUN2000L has connected to the router.
