ABB / Power One Inverter E031 fault

Inverter showing E031 fault

If your ABB (or Power One) inverter is displaying the E031 error, as shown in the photograph, then it has suffered an internal error due to a hardware failure.

Firstly, you need to ascertain if the inverter is still under warranty. These inverters were sent out from the factory with a five year warranty but some installers extended the warranty to ten years.

If your inverter is still within warranty, or if you aren’t sure, then please phone ABB first on 01903 823323. They will require the serial number, which is printed on a label on the right hand side of the inverter. If the inverter is within its warranty period then ABB will arrange for their agent to repair or replace the inverter free of charge.

If your inverter warranty has expired then we can discuss compatible alternatives with you, which you can purchase from our Online Shop should you feel confident to replace it yourself. A great replacement for the PVI-3.0OUTD is a Solis 3.0, or if you don’t require a dual MPPT model the Solis 3.0 mini. To replace a PVI-3.6OUTD we recommend a Solis 3.6 for dual MPPT, or Solis 3.6 mini for single MPPT applications. Call us if you’re unsure which inverter you require.

We can supply our Solis range of inverters with a ten year warranty for your peace of mind, simply add the warranty during checkout. We also have great value inverters from Growatt and GoodWe.

We also offer a full supply and fitting service within a reasonable distance. Please get in touch.

Note: Power-One were acquired in 2013 by ABB. Inverters purchased in 2013 or later may be branded Power-One or ABB. The models are the same and warranties unaffected.
