6.1 Commissioning the Inverter
1. Check the following requirements before commissioning:
– The inverter is securely in place
– AC cables are correctly connected (electricity grid)
– DC cables (PV strings) are fully connected
– Unused DC inputs are closed using the corresponding DC connectors and sealing plugs
– The enclosure lid is securely screwed into place
– The Electronic Solar Switch is securely connected
– The miniature circuit-breaker is correctly sized
2. Switch the miniature circuit-breaker on.
☑ All three LEDs glowing or flashing: the startup phase commences.
☑ Green LED is glowing: commissioning successful.
or
☑ Green LED will flash if irradiation is insufficient: grid connection conditions have not yet been
reached. Wait for sufficient irradiation.
or
☑ The red or yellow LED is glowing or flashing: there is a disturbance. Proceed to step 3.
3. Read Section 9 "Troubleshooting" (page 58) and if necessary, eliminate the fault or
disturbance.
A Green LED Operation
B Red LED Earth fault or varistor defective
C Yellow LED Disturbance
Self-test in accordance with CEI 0-21 during initial start-up of SMC 6000A
(applies to Italy only)
The Italian standard CEI 0-21 prescribes that an inverter can only operate on the electricity
grid after the disconnection times for overvoltage, undervoltage, minimum frequency and
maximum frequency have been checked.
Start the self-test as described in Section 6.2 "Only for Italy: Self-Test in Accordance with
CEI 0-21" (page 45). The test takes approx. 8 minutes.
