11. Connecting the PV array

These units have two MPPT inputs for connecting two independent PV arrays.
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 arrays cannot be grounded, so their 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. Check that the
protections for the grid/genset, critical loads, storage system and PV arrays are open.
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.
