Requirements:
☐ The AC circuit breaker must be correctly rated and mounted.
☐ The inverter must be correctly mounted.
☐ All conductors must be correctly connected.
☐ Unused enclosure openings must be sealed tightly with sealing plugs.
Procedure:
1. Lead the enclosure lid to the Connection Unit and
plug the ribbon cable into the socket on the
communication assembly.
2. Ensure that the ribbon cable is securely plugged into the sockets at both ends.
3. Position the enclosure lid of the Connection Unit on the enclosure and tighten all 6 screws
crosswise (TX 25, torque: 3 Nm ± 0.3 Nm (26.55 in-lb ± 2.65 in-lb)).
4. Switch on the AC circuit breaker.
5. Switch on the battery or the load-break switch of the battery (see documentation of the battery
manufacturer).
☑ All three LEDs light up. The start-up phase begins.
☑ All three LEDs go out again after approximately 90 seconds.
☑ Depending on the available power, the green LED pulses or is continuously illuminated.
The inverter is feeding in.
6. If the LEDs do not start to glow, the ribbon cable between the assembly in the enclosure lid
and the communication assembly in the inverter is most likely not properly plugged in. Ensure
that the ribbon cable is securely plugged into the sockets at both ends.
7. If the green LED is still flashing, the conditions for activating feed-in operation are not yet met.
As soon as the conditions for feed-in operation are met, the inverter starts with feed-in
operation and, depending on the available power, the green LED will light up continuously or
it will pulse.
8. If the red LED lights up, an error has occurred. Rectify the error (for information regarding
troubleshooting see the user manual under www.SMA-Solar.com).
