Requirements:

☐ All inverters must be correctly mounted.
☐ The PV modules must be correctly mounted.
☐ The circuit breaker must be correctly rated.
☐ The Sunny Multigate must be correctly installed in the industrial enclosure.
☐ The unused AC pin connector on the last inverter of the PV system must be sealed with a

protective cap.

☐ The AC cable of the utility grid must be correctly connected to the Sunny Multigate. All

conductors must be connected in accordance with the terminal labels. No conductors must be
swapped.

Procedure:

1. Connect the AC cables to the inverters (see Section 6.3 "AC Cabling of the Inverters", page 31

to the Sunny Multigate", page 36). All conductors must be connected in accordance with the
terminal labels. No conductors must be swapped.

3. Connect the PV modules to the inverters (see Section 6.8 "Connecting the PV Modules to the

Inverters", page 40).

4. Remove the cover of the PV modules.
5. Switch on the two-pole circuit breaker.

☑ Both LEDs on the Sunny Multigate are glowing green. Feed-in operation begins.
