SMA Solar Technology AG 10 Troubleshooting
1. Disconnect the inverter from all voltage sources (see section 9).
If there is no conductive connection, the varistor is defective. SMA Solar Technology AG
recommends replacing all varistors immediately.
• Order new varistors and insertion tools (see section 13 "Accessories", page 91).
• If new varistors are available, replace all varistors (see section 10.9).
If a conductive connection is present, contact the SMA Service Line.
2. Use a multimeter to measure whether there is a
conductive connection between the middle
connection wire and the right-hand connection
wire.
