Connecting the inverter to the PV generator
The inverters of the TP series are operated in dual tracking mode. In the dual tracking
mode a separate MPP tracker is available for each DC input.
Connection conditions
■
■
Connection of maximum 2 strings (1 string in the case of SM4TP)
DANGER!
Risk of death by fire!
High return currents can cause a fire risk for the PV generator.
■
■
When Y plugs are used in order to connect more than 2 strings (more than
1 string in the case of SM4TP), each DC feed cable must be protected
individually against dangerous return currents.
■
■
Maximum DC input current: 10 A per DC input
■
■
Maximum DC input voltage: 900 V
■
■
Select the conductor cross-section to suit the system configuration.
