5.7 Application examples for single-MPPT operation
This section shows two examples of applications using three SM330TS-SV inverters and
a TS-SV-MCU in each case. Both stations are designed for single-MPPT operation.
In the example in subsection 5.7.1 three DC bus bars are used. One DC bus bar for every
central inverter. The DC bus bars are connected to each other with connection cables.
The 315 amp fuses protect the connection cables. If the currents are balanced, no current
flows in the connection cables. If the currents are not balanced, the current in the con-
nection cables will not exceed 315 amp. The 315 amp fuses allow individual inverters to
be disconnected from the DC input.
In the example in subsection 5.7.2 all DC inputs of the central inverters are connected in
parallel to a common DC bus bar. In that case, the connection cables are not necessary.
The 315 amp fuses can be dropped. Arrange the connections over the entire length of the
DC bus bar, so that the current at a certain point cannot exceed 960 amp.
