SMA Solar Technology AG

If the red LED is flashing and the inverter displays the message

Check Varistor

, one of the varistors

may be defective. Check the function of each varistor as described in the following.

Position of the Varistors

Destruction of the inverter due to overvoltage

If varistors are missing, the inverter is no longer protected against overvoltage.

• Do not operate the inverter without varistors in plants with a high risk of overvoltages.
• Do not recommission the inverter until the defective varistors have been replaced.

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range up to 1,000 V.
