SMA Solar Technology AG 10 Troubleshooting
Requirements:
☐ A retrofit kit with five string fuses and five fuse extractors must be available.
☐ All string fuses must be removed.
Proceed as follows to replace each string fuse:
1. Disconnect the inverter from all voltage sources (see section 9).
4. Commission the inverter (see section 8 "Commissioning", page 51).
10.11 Replacing the String Fuses
Damage to the inverter due to string fuse burn-off
It cannot be guaranteed that commercially available string fuses will function correctly. In the event
of an error, the string fuses can burn off.
• Install only string fuses available from SMA Solar Technology AG in the inverter.
2. Insert a new string fuse in a new fuse extractor.
3. Insert the fuse extractor with the string fuse in the
fuse holder.
10.12 Cleaning the Inverter
Damage to the display by use of cleaning agents
• If the inverter is dirty, clean the enclosure lid, the display and the LEDs using only clean water
and a cloth.
