Signs your inverter is not working

  • If your FIT meter is showing that you are generating no energy or far less than normal then it could be because it your inverter has an issue.
  • Error messages on the inverter or warning light also give vital clues that something is wrong.

It is important that a PV engineer visits and tests the system and identify exactly what the problem is. Many of the problems we encounter while inspecting solar systems are fixed within an hour and are covered by the callout fee.

Our Services

Our experienced engineers will conduct a thorough investigation, not just of the inverter but of your whole system to pinpoint where the problem is and get it resolved as quickly as possible.

Sometimes the inverter just can't be fixed or its not cost effective to do so. If this is the case & the inverter is still within it's manufacturers warranty, we will ensure that all the necessary details are available for you to claim back directly from the manufacturers. If the warranty has expired then we can assess your solar PV system using a Solar Design Program which calculates the best replacement inverter for you by reviewing all kinds of factors including the location of your home and the number and positioning of your panels.

Very helpful engineer who explained options clearly and did an excellent job. He telephoned before the job analysed the problem and brought the correct equipment which meant that he did not need to go back to acquire spares
