      SolarEdge Status Codes

      All of the SolarEdge inverter status codes, meanings and solutions.

      Below is a list of the various codes that may appear on your SolarEdge inverter. We recommend restarting your inverter if any issues do arise. 

      Just like restarting your computer, restarting your inverter can fix some common issues.

      These common issues include: 

      • Faults and errors that are displayed on the inverter (take note of these before restarting your inverter in case the error continues). These may relate to external factors like grid voltage or wiring
      • The system not communicating with internet monitoring (you may also need to restart your modem)
      • If the system is generally not performing as it should

      In the event that restarting your inverter doesn’t work, here is a list of what to do in the event of each SolarEdge status code.

      112

      Wrong AC Connection

      The lines connections

      to the inverter are

      incorrect, for example:

      AC line 1 from the grid

      is connected to line 2 at

      the inverter so there is

      no 120deg between L2

      to L1 and L3 to L2 at the inverter side.

      Switch between L1 and L2 or L2 and L3 connections.

      N/A

      AC Current Stage

      Internal hardware

      that measures AC

      current has measured

      substantially high

      output currents. This

      may occur because of

      changes in the AC

      voltage or a switching load near the site.

      If the fault persists: 

      • Check the AC connection to the

      inverter.

      • Check with the grid operator if a large

      surge source or irregular load exists

      near the site.

      • If the fault persists, contact SolarEdge support or your solar provider. GEM Energy support 1300 969 471.

      Ground Current - RCD

      Ground current surge. The internal hardware that measures ground fault has measured substantially high ground currents.

      Ground faults may occur due to insufficient insulation to the ground. ELECTRICAL HAZARD. Do not touch insulated wires when the inverter cover is removed. Only a qualified electrician should handle this problem and only after taking proper precautions. 


      1 Turn the inverter ON/OFF switch to

      OFF.

      2 Wait five minutes for the input

      capacitors to discharge.

      3 Disconnect the AC breaker.

      4 Disconnect the DC inputs.

      5 Connect each DC string separately,

      turn the AC and the inverter ON/OFF

      switch to ON, until the error appears

      for the faulty string.

       

      • Do not connect strings with a grounding fault to the inverter.
      • For further documentation about possible ground current error sources and solutions contact SolarEdge support.
      • A certified installer must fix the faulty string before connecting it to the inverter.

      AC Voltage Too High (Line 1/2/3)

      AC voltage surge. The

      High

      internal hardware that

      measures AC voltage

      (Line 1/2/3)

      has measured

      substantially high

      sudden output voltage.

      If the fault persists:

      • Check the AC connection to inverter.
      • Verify that the inverter is set to the correct country.
      • Check with the grid operator if a large surge source or irregular load exists near the site.
      • Verify that the output wire size matches the distance between the inverter and the location of the grid connection.
      • Use a larger gauge wire for the AC output.
      • Refer to the AC Wiring Application Note, available on the SolarEdge website at http://www.solaredge.com/files/pdfs/application-note-recommended-wiring.pdf

      102

      DC Voltage Too High

      DC overvoltage.The input DC voltage exceeds the maximum supported level.

      The SolarEdge system normally eliminates

      DC overvoltage errors: When DC

      overvoltage is detected, the inverter shuts

      off the power optimizers and restarts.

      If the fault persists:

      • Turn OFF the inverter ON/OFF switch.
      • If after five minutes, the LCD panel does not show a low safety voltage (1V per optimizer), check which string is malfunctioning, and recheck its connections to the inverter.
      • Proceed according to Power Optimizers Troubleshooting on page 57
      • Re-commission all inverters in the site, as described in Chapter 4: Commissioning the installation

      Temperature Too High

      Over temperature.

      If the fault persists:

      isolation is checked

      each time the inverter starts up.

      If the fault persists:

      Check the PV installation for isolation

      problems and ground leakage.

      Only a certified PV installer must fix the

      faulty string before connecting it to the inverter.
