Inverter Neutral Connection
7.2.1
Inverter Connected to the Grid
When connecting the inverter to AC from the grid, the inverter input must not be connected
via an earth leakage.
The earth leakage must be connected directly after the inverter.
Keep the inverter neutral input connected to the
GRID neutral
at all times.
Connect the inverter Earth to the Earth Bar on the DB board.
When switching off the GRID input to the inverter, only
SWITCH OFF LIVE
.
Refer to Figure
7-2
The grid will pull the inverter neutral to 0v.

Off-Grid Connection
For an
OFF-GRID
application you need to bridge the
Neutral Input
to the
Earth
terminal on
the inverter AC wiring terminal block.
You can now fit an earth leakage after the inverter.
