8 Recommissioning the Inverter
• Check the metal mounting tabs inside the ESS
for discoloration or damage.
If the metal mounting tabs show brown
discoloration or are damaged, order a new
ESS from SMA Solar Technology AG and have
the ESS replaced.
If the metal mounting tabs show no brown
discoloration or damage, the ESS is not worn
and can still be used.
12. Switch on the circuit breaker of all three line conductors.
13. If necessary, update the firmware of the communication assembly.
14. Securely plug in the ESS. The ESS must be aligned parallel to and flush with the enclosure.
15. If the multifunction relay is used, connect the supply voltage to the load.
☑ All three LEDs start to glow and the start-up phase begins. The start-up phase may take
several minutes.
☑ The green LED is glowing and the display alternates between the device type, the
firmware version, the serial number or designation of the inverter, the NetID, the
configured country data set and the display language.
16. Perform the respective measures indicated when the following LED status appears:
LED status
Green LED is
flashing
The red LED is
glowing and an
error and event
message appear
in the display.
17. After replacing the assembly, check the correct functioning of the SELV circuit. Activate the fan
test for this purpose:
• Call up the user interface of the communication product or software and log in as Installer
or User.
• Select the parameters Device > Cooling system > Fan test. If the fan starts, the SELV
circuit is fault-free. If the fan does not start, contact Service.
18. Ensure that the inverter feed in correctly.
19. Perform the VAC test (see Section 9, page 31).

Cause
The DC input voltage may still be
too low or the inverter is monitoring
the utility grid.
The inverter has detected an error.
SMA Solar Technology AG
Measures
Wait that the DC input voltage is suf-
ficiently high and the grid-connec-
tion conditions are met. Then the in-
verter will start operation automati-
cally.
Eliminate the error (see the inverter
manual).
