1System Description
1.1 Introduction
EMS300 is a web-based local monitoring system. Addressing the problems of unused
surplus wind and PV power, unstable loads, and different electric prices between peak
and off-peak hours, it balances power supplies and demands economically and
efficiently under different application scenarios and operation modes by optimizing
energy storage control and distributed power output and coordinating the
commissioning and ceasing of loads.

step 1 Use the Ethernet cable to connect the PC to the EMS300.
step 2 Configure the IP address of the PC and that of the Ethernet ports (FE1 ~ FE4) of the
EMS300 to the same network segment. The IP address of the Ethernet port is shown
below. Taking port FE2&FE3 of controller 2 as an example, the default IP address of
Ethernet ports is 12.12.12.12. The IP address of the PC can be set to 12.12.12. X and
the subnet mask to 255.255.255.0.

The IP address of the above port is for reference only, please refer to the
actual one!
step 3 Enter the IP of the Ethernet ports in the address bar, to enter the default interface.
If you accidentally forget the IP address of the Ethernet ports, you can log in
with the virtual IP. The virtual IP of the Ethernet port is 15.15.15.15, available
for FE2&FE3 ports only.
step 4 Select the desired language in the upper right corner of the interface, and click LLooggiinn.
Enter the password pw1111 to access the web interface.
User types include ggeenneerraall uusseerr and OO&&MM UUsseerr.
The general user can view basic information, real-time fault, and device
monitoring information of the system.
In addition to all permissions of the general user, the O&M user has the
permission to set and modify parameters and control methods of the system.
In the following, description is given by using the O&M permission as an
example.

After login for the first time, it is recommended to change the password as
soon as possible. Click OO&&MM UUsseerr→→MMooddiiffyy PPaasssswwoorrdd to change the
password.
With the login password forgoten, contact SUNGROW and provide the device
S/N as well as system time, to get the password.
