5.4 MPP Tracker
In the “Operation” status (see Chapter 5.1.3), the inverter detects
the maximum power point (MPP) of the PV cells.
The MPP tracker detects the point at which the solar cells give off
maximum power.
This enables the system to achieve optimum efficiency.

5.5 Partner Operation
In “partner operation”, the efficiency of a system with two inverters
can be increased by connecting the two PV cells at less than full
power.
If insolation levels fall, the PV cells are connected and only one in-
verter is in operation.
If insolation levels rise, the connection is terminated. Now both in-
verters are in operation. Each inverter is supplied with power by its
associated PV panel.
5.5.1 Linked Operation
One inverter is switched on and is feeding power into the mains.
The other inverter is logically switched off. The tie switch is closed.
The inverter which is active in linked operation changes daily.
This operating mode is active when insolation levels are low.
