What does it mean when an inverter is described as 'unresponsive'?

• It is exhibiting no signs of life

• It is producing too much power

• It is showing error messages

• It is overheating

What should be done before working inside the inverter while AC power is present?

• Ensure Red IO Toggle Is ON

• Ensure Red IO Toggle Is OFF

• Ensure Red IO Toggle Is SET

• Ensure Red IO Toggle Is PAUSED

What should be checked if the AC voltages reaching the inverter are within specifications?

• The Fuse

• The Communication Board

• The Power Supply Output Voltage

• The Digital Board

What should be done if the fuse has failed in the inverter?

• Ignore it and continue using the inverter

• Contact SolarEdge Technical Support

• Replace it with a 750ma/250v Slow Blow fuse

• Replace it with a 500ma/250v Slow Blow fuse

What should be disconnected if the fuse is good but the inverter remains unresponsive?

• ZigBee and Cellular devices

• All devices connected to the communication board

• SD cards and Ethernet cables

• RS485 terminal blocks and Ethernet cables

What should be checked if removal of devices has not corrected the unresponsive behavior?

• Power Supply Output Voltage

• Fuse Continuity

• DC Voltage on the Communication Board

• AC Power

What should be done after checking the Communication Board Test Point?

• Contact SolarEdge Technical Support

• Remove the Communication and Digital Boards

• Check the Fuse

• Check the Power Supply Output Voltage

What should be measured after turning AC power back on and inserting meter probes across TP 700 and TP 701?

• AC Voltage

• DC Voltage

• Fuse Continuity

• Power Supply Output Voltage

What information should be gathered to contact SolarEdge Technical Support?

• Fuse Continuity

• Open-air string voltages

• Inverter model number

• AC Power status

What should be done if a device is causing the unresponsive behavior?

• Ignore the issue

• Replace the inverter

• Continue using the faulty device

• Contact the equipment manufacturer
