Connecting The Ac-Output Cable - Aros 10000P Manual De Instrucciones

5.3 Connecting the AC-Output Cable

1. The inverter contained in this box has been designed to operate with TT,
TN or TN-S low voltage grids. If this inverter is connected to a different
kind of grid, for example IT grids, it is possible to get the following errors:
"ERR ISOLATION" or "ERR MICROS"
2. Each country has its own rules regarding the maximum power that can
be connected to the grid without a transformer. If it is necessary to
connect this inverter via a grid frequency transformer, it is necessary to
create the correct kind of grid locally: TT or TN. In order to do this, it is
necessary to ground the neutral point of the transformer. Some
examples of connection are available in the appendix, in "Table 3". The
numbers in the table have the following meaning:
1. The neutral point is not grounded: IT system
2. The galvanic insulation required by the grid management is
3. The neutral point on the grid side is not connected. The three
3. In the case of PV systems connected to the grid through a medium to
low voltage transformer room, it is necessary to ground the neutral point
on the low voltage side.
4. It is strongly advisable to use the end pipes included in the pack to wire
the output terminal block of the inverter. In case of difficulties, it is
possible to insert the pipes without crimping them, allowing the screw of
the terminal block to tighten them around the cable.
missing and measurement errors are caused in the inverter.
star voltages on the inverter side vary greatly depending on the
amount of power fed to each phase.
