We had 3.5Kw of PV installed in 2011. On Friday the Inverter an Aurora PVI-3.6-OUTD-UK failed Err EO31
I have contacted my installer, who is still in business to see what they suggest, guessing a new inverter costing probably 500 upwards!
Have been doing a bit of searching online and find I could get a replacement of the same model(second hand) delivered for 220, probably limited warranty if any. Swap the inverters over and send the old one for repair, quoted 110 for repair and carriage both ways. This would give me a spare for any future failure!
What would you consider to be the best option new with 5year? warranty or refurbished at half the cost?
I am well over the "three score years plus ten" so it is debatable as to what the next failure might be!

Why not just get yours repaired? What warrantee do they give on the repaired one? If they can't repair it then you obviously have to decide which way to go, but by the time it fails again (if it does) replacements might be significantly less expensive anyway.

Well if quickest is the issue you need to get some idea of how long each option will take. Even if you are missing an inverter for a week, you could easily work out how much lost FIT/export that would cost you.  I have no idea on the turn around for repairs, and you have not given any (3 days, a week, a fornight, a month?), how long would delivery be on a new one or the second hand one. In all cases who will be fitting it, you are do you need to get an electrician, if so what lead time? No point in paying for next morning delivery (if they give that option) and finding that your man is then on holiday for 3 weeks!

Read here -(you may already have) .http://www.hembrow.eu/electronics/abbpoweroneaurorainverter.html
-Buys relay online.
- Remove pcb yourself -label wires and take photos as you do.
-send printed copy of hyperlink with pcb with new relays to a local electronics repairer (can recommend one )
Cost me less than 30 including return postage .48 hrs .

Is there a commonality between these two threads regarding the fault/error code E031?

Possibly due to the same cause, CR2032 battery, 2.50 in most chemists and supermarkets.

Just an update on this post.
Original installer no longer does PV and declined to help. Two other local installers were not interested in replacing a faulty inverter.
Was in the throes of searching ebay for a suitable replacement when I came across another repair advert from someone just 20 minutes away, delivered inverter there last night - arrangement is no repair possible then no charge!
