11. Connecting the PV array
These units can be connected to a PV array.
This chapter explains the requirements and process for connecting the PV array wiring to the unit. Read carefully
before starting the connection process.
CAUTION
The PV array cannot be grounded, so its terminals must be isolated from ground.
INFO
The inverter will only start if the ground impedance of the PV array is higher than 18.3 kOhms.
11.1. Safety instructions for connecting the PV array
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 unit.
Ingeteam accepts no liability for any damages caused by an incorrect connection.
