13.1 Password Change Requirements
After initial login, change the HMI password (1111) to a site-unique password with 4
numbers.
It is recommended to change the password every 6 months. If the password needs
to be reset, please contact Sungrow.
13.2 Port Protection and Isolation
Ensure that the inverters are installed such that the network zone has ingress
protection and minimized port exposure. The network should have an independent
subnet that is physically isolated.
Ensure that network security protections are in place to ensure physical isolation
of the Firewall and Ports.
If a DNS service is used, ensure that the inverter has access to this site-specific
DNS server. Change the DEFAULT DNS server to local DNS service provider.
13.3 Network Cables and Tamper Evident Seals Inspection
When tamper evident seals are broken, ensure that these are removed and
replaced.
