5.4.4 Residual current protection
The inverter is equipped with an all-pole sensitive residual current monitoring unit (RCMU) with an integrated differential current sensor which fulfills the requirements of DIN VDE 0100-712 (IEC60364-7-712:2002). Therefore an external residual current device (RCD) is not required. If an external RCD needs to be installed because of local regulations, a RCD type A or type B can be installed as an additional safety measure. The all-pole sensitive residual current monitoring unit (RCMU) detects alternating and direct differential currents. The integrated differential current sensor detects the current difference between the neutral conductor and the line conductor. If the current difference increases suddenly, the inverter disconnects from the grid. The function of the all-pole sensitive residual current monitoring unit (RCMU) has been tested in accordance with IEC 62109-2.
Tip about the external residual current device (RCD)
Where an external residual current device (RCD) is required in a TT or
TN-S system, install a residual current device which trips at a residual current of 100mA or higher.
For each connected inverter, a rated residual current of 100mA has to
be provided. The rated residual current of the RCD must be equal to at least the sum of the rated residual currents of the connected inverter.That means that, if, for example, 2 transformerless inverters are connected, the rated residual current of the RCD must be at least 200mA.
Installation and Operating Instructions V02 27
5.4.5 Overvoltage category
The inverter can be deployed in grids of installation category III or lower, as defined under IEC 60664-1. This means that it can be permanently connected at the grid-connection point in a building. In installations involving long outdoor cable routing, additional overvoltage-reducing measures must be taken so that the overvoltage category is reduced from IV to III.
5.4.6 Rating of AC circuit breaker
No consumer load should be applied between AC circuit breaker and the inverter. Use dedicated AC circuit breakers with load switch functionality for load switching. The selection of the AC circuit breaker rating depends on the wiring design (wire cross-section area), cable type, wiring method, ambient temperature, inverter current rating etc. Derating of the circuit breaker rating may be necessary due to self-heating or if exposed to heat. The maximum output currents of the inverters and recommended AC circuit breaker can be found in the following table.

42 Installation and Operating Instructions V02
7.3 Start-up
After finishing the electrical and mechanical checks, switch on the AC circuit breaker and DC switch in turn. Once the DC input voltage and power are sufficiently high and the grid-connection conditions are met, the inverter will start operation automatically. Usually, there are three states during operation:
Waiting: When the initial voltage of the strings is greater than the minimum DC input voltage but lower than the start-up DC input voltage, the inverter is waiting for sufficient DC input voltage and cannot feed power into the grid.
Checking: When the initial voltage of the strings exceeds the start-up DC input voltage, the inverter will check feeding conditions at once. If there is anything wrong during checking, the inverter will switch to the ‛Fault“ mode.
Normal: After checking, the inverter will switch to ‛Normal“ state and feed power into the grid.
During periods of low radiation, the inverter may continuously start up and shut down. This is due to insufficient power generated by the PV generator. If this fault occurs often, please call service.
