You can verify if there is a voltage when the inverter is disconnected from the grid by using a simple
multimeter.
NOTE:
Only for South Africa – Using a permanent PE/N bond on LOAD OUTPUT is recommended, and the
supply power to the grid port needs to be taken from the mains before the main RCD to prevent RCD
from tripping.
The bond we recommend being done in the external box clearly marked “permanent PE/N bond“, and
this has been advised by local authorities.
