Auxiliary genset connection

10. Auxiliary genset connection
This chapter explains the requirements and process for connecting the auxiliary genset to the unit.
DANGER
Identify the correct type of hardware before carrying out the connection to the grid (see "2.2. Types of
hardware"). Danger of electrocution due to an incorrect connection of the neutral conductor.
INFO
In both types of hardware it is possible to use the TT and TN grounding systems. For inverters with hardware
type A with a TN connection, please contact Ingeteam for more information.
If the neutral conductor is connected incorrectly, the consumption grid ground connection will not work. In TT
systems, the internal transfer relay must disconnect the neutral conductor between the consumption grid and the
auxiliary genset when the inverter is not connected to the auxiliary genset. However, in TN systems the neutral
conductor must be the same one between the consumption grid and the auxiliary genset, therefore it cannot be
disconnected.

10.1. Safety instructions for connecting the auxiliary genset

CAUTION
Before you start to make the connections, make sure there is no voltage in the inverter. Verify that the AC
protection of the auxiliary genset and the DC protection of the storage system are open, as well as the PV array
and the consumption grid.
Do not switch on the power to the unit until you have successfully made the rest of the connections and the unit
is closed.
When carrying out the connections, respect the polarities marked on the electronic card.
