5 Installation
Additionally required material (not included in the scope of delivery):
☐ Distribution board with required electric equipment
☐ Two electrical current strength transducers (mechanical and electrical characteristics of the
selected electrical current strength transducers must be in accordance with the installation on
site)
☐ One router for the connection to the Internet. SMA Solar Technology AG recommends using
an Internet flat rate.
☐ One switch
☐ Network cable
☐ Data cable of battery
Switch requirements:
☐ At least 5 Ethernet connections must be available
☐ The switch must be permeable for broad and multicasts
