as required by IEC 62446-1 Clause 6.5.3.
To take a measurement:
1. Connect the PV string to the inverter and switch the system to on and normal operation
mode (inverter must be at maximum power point).
It is useful to connect two Y-connectors in between so you can measure the string voltage
in parallel.
2. Turn the rotary switch to V
