If the sensor is not installed and configured, the inverter will not be able to connect to the AC grid as the AC contactor will stay open.

Before performing any work on the inverter, follow the procedure for turning off the inverter. If work has to be carried out on exposed parts (not protected by panels), opening the AC and DC disconnect switches (position 0) is not enough as a safety measure as the input cables are always live.
