7.3.1 Before connecting
Ensure that there is no ground fault
1. Determine the DC voltage and resistance on the PV generator for:
–
protective earth (PE) and positive cable
–
protective earth (PE) and negative cable
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.
In addition, ensure that the PV generator has a total insulation resistance of more than 2.0 MOhm, since the
inverter will not feed in if the insulation resistance is too low.
2. Rectify any faults before connecting the DC generator.
7.3.2 Maximum input power
The input power of the inverter is limited only by the maximum rated current per input. This causes the maximum
input power per path to increase with the input voltage.
NOTE
The overall power of the unit continues to be limited. If one input is connected to more than
P(DCmax)/2, the maximum input power of the second input decreases accordingly. Take care that
the maximum input power is not exceeded.
7.3.3 Recommended connections
DANGER
Risk of fatal injury due to electric shock (electric arc)!
Wrong assignment of MPP trackers will seriously damage the inverter
Severe injury or death will result if the live connections are touched.
›
Make sure that each MPP tracker can be disconnected from all poles.
›
Observe recommended standard connection.
