SMA Solar Technology AG 8 Commissioning
Initial Start-Up
When commissioning the inverter for the first time, proceed as follows.
Requirements:
☐ The miniature circuit-breaker must be correctly rated.
☐ The inverter must be correctly mounted and closed.
☐ All cables must be correctly connected.
☐ Unused DC inputs must be sealed using the corresponding DC connectors and sealing plugs.
☐ The ESS must be securely plugged in.
• Switch on the miniature circuit-breaker.
☑ The start-up phase begins. All three LEDs are glowing or flashing.
☑ The green LED is glowing and the start-up phase begins. The display shows the device type,
firmware version, country data set and operating mode of the SMA Power Balancer
consecutively. After the start-up phase has been completed, the current power, reactive power
and displacement power factor cos φ are displayed.
✖ Have all LEDs gone out?
The ESS is not plugged in or there is no DC input voltage.
• Plug in the ESS securely or wait until DC input voltage is present.
✖ Is the green LED flashing?
The DC input voltage is still too low.
• Once the DC input voltage is sufficiently high, the inverter will start to operate.
✖ Is the yellow or red LED glowing or flashing?
There is probably a fault or warning present.
• Rectify the fault or warning (see section 10.1 "LED Signals", page 56).
Recommissioning
If you have disconnected the inverter (e.g. for configuration purposes) and want to recommission it,
proceed as follows.
☐ The miniature circuit-breaker must be correctly rated.
☐ The inverter must be correctly mounted.
