IEC 60364-6 6.4.3.3 describes two options for this case. The first option is to disconnect devices with an overvoltage conductor or, if this is not practicable, then the test voltage can be reduced to 250V Page 5 KACO blueplanet 3.0 - 20.0 NX3 M2 3 Description of the device 3.1 Mode of operation The device converts the DC voltage generated by the PV-modules into AC voltage and feeds this into the power grid. The starting procedure begins when there is sufficient sunlight and a specific minimum voltage is present in the device. The feedin process begins once the PV generator has passed the insulation test and the grid parameters are within the requirements imposed by the grid operator for a specific monitoring time. If, as it gets dark, the voltage drops below the minimum voltage value, feed-in mode ends and the device switches off. 3.2 System layout Key PV generator Inverter with circuit-breaker Line protection Feed-in meter Selective main switch Reference counter DC integrated isolator switch Fig. 2: Circuit diagram of a system with two inverters Definition / information on the connection The PV generator converts the radiant energy of sunlight into electrical energy.

The inverter will clip to the maximum AC power output. The "Max. short-circuit current (ISCmax.)" defines together with open circuit voltage (UOCmax) the characteristic of the connected PV generator. This is the relevant value for string sizing and is the absolute maximal limit for inverter protection. The connected PV-Generator must be designed, that the max short circuit current is below or equal to ISCmax of the inverter under all foreseeable conditions. In no condition the design may result in a greater short circuit current than ISCmax of the inverter.

Ensure that there is no ground fault 1 Measure the DC voltage between the protective earth (PE) and the positive cable of the PV generator. 2 Measure the DC voltage between the protective earth (PE) and the negative cable of the PV generator. Page 17 KACO blueplanet 3.0 - 20.0 NX3 M2 If stable voltages can be measured, there is a ground fault in the DC generator or its wiring. The ratio between the measured voltages gives an indication as to the location of this fault. 3 Rectify any faults before taking further measurements. 4 Measure the electrical resistance between the protective earth (PE) and the positive cable of the PV generator. 5 Measure the electrical resistance between the protective earth (PE) and the negative cable of the PV generator. In addition, ensure that the PV generator has a total insulation resistance of more than 2.0 MOhm, since the device will not feed in if the insulation resistance is too low. 6 Rectify any faults before connecting the DC generator. Possible wiring Two DC strings for each MPP tracker The MPP voltages of the two DC strings can be different. They are supplied by separate, independently operating MPP trackers (MPP trackers A and B) Number of modules per string: Pmax : per string < 0.6 * max. recommended PV generator power MPP tracker A+B together < max. recommended PV generator power Imax: Depending on PV generator The input current per MPP tracker must not be exceed 40 A Fig. 22: Recommended standard connection 7.5.4 Connection in parallel operation Possible wiring Both MPPTs must be connected individually to the generator junction box. The DC inputs can also be connected in parallel. In this case, only lines with the same MPP voltage may be connected in parallel(Un1=Un2=Unx) Number of modules per string: When using the MPP Trackers in parallel mode, the maximum allowed power is 1,1x rated power. Also the maximum MPPT current is limited by the lowest value of all MPPTs. For example, if the 15kW inverter is used in parallel mode, the maximum allowed power is 1,1x 15kW = 16,5kW and each MPPT current is limited to 20A (since one MPPT is rated for 32A and the other is rated for 20A).
