Requirements:
☐ The inverter must be correctly mounted.
☐ The circuit breaker must be correctly rated.
☐ All cables must be correctly connected.
☐ A computer with a WLAN- or Ethernet interface or a tablet PC or smartphone with a WLAN
interface must be available.
Procedure:

position I.
2. Switch on the circuit breaker.
☑ The green LED flashes for approx. 30 seconds and then glows permanently or pulses.
Feed-in operation begins.
✖ The green LED is still flashing after one minute?
The DC input voltage is still too low.
• Once the DC input voltage is sufficiently high, feed-in operation begins.
✖ The red LED is glowing?
An error has occurred.
• Rectify the error (see service manual at www.SMA-Solar.com).
3. Configure the inverter via the user interface (see Section 8.1.1 "Calling Up the Inverter User
Interface via Direct Connection", page 34). When doing so you can either configure the
inverter manually, use the installation assistant or adopt an existing configuration from a file.
SMA Solar Technology AG recommends configuration with the help of the installation
assistant.
