do you have a solution for the Riso low 0.00MOhm message? the installation of the panels is correct because it works properly on another inverter. Regards
That there was very interesting, taught me lots about electronic circut boards. Think Ill send them my board to fix when I can contact them
Hi @Pete Bransgrove! Thanks for your comment and positive feedback, and good luck with getting your inverter fixed!
you can set the parameter „Vstart“ for each of the two inputs (Mpp trackers) down to 120 Volts - thats the low limit for starting the inverter to work.
press Esc and manuver to „settings“, than put in four times zero „0000“ as the password. After that you can adjust the basic settings.
For grid protection settings you will need a six-digit password, can be generated by the support of Fimer (taken over the business from ABB Solar).
sunny greetings
Hi @Gonzobuster! Thanks for sharing.
Hello, Nice to know a fix is possible and working in case of 031. That said, mine display "Mising grid". I checked with DMM, the 230V is present on terminals. Any idea of what the failure could be? I need to kinow where to focus before dismantling the whole unit. Thanks!
Thanks HD for this interesting video.
One of my friends and myself have got the same Aurora inverters aged some 12y now.
The one of my friend just failed with the E031 fault code and I expect mine to do the same at any time.
If I'm right these relays are in charge of switching the inverter to the grid once a sufficient voltage is provided by the solar panels. So, as lower this threshold (can be set in the settings) as more current you're obviously going to provide to the grid but as more these relays are going to work by switching off and on (especially outside summer time)..... And subsequently as sooner they might be failing. Does this make sense to you ?
I'm not sure changing the threshold when the inverter kicks in would affect the current going through the relays, as there's not that much mains power being inverted when the panels are not lit strongly. Replacing the relays for new and strengthening the solder joints will give the unit a new lease of life. Thanks for your kind comments and interest.
Thanks very interesting. I have the same inverter and it failed 2 years in with the same error code. I got mine replaced by ABB who have taken over guarantee work. But I have seen Andy's repair on his site showing the relay failure.
Hi @Martin Winfield, interesting to hear! It's a shame but looks like these units are dropping like flies almost everywhere! Glad to hear you managed to get yours replaced. Thanks for your support!
Hi, where did you source the relays from. Thanks.
Hi @peter wainwright - thanks for the comment! The relays can be sourced from different suppliers however if you search it into the internet the most popular should be on sites like Amazon or Ebay. Make sure you're getting them in the "Brand New"" condition! By the way, we used Rapid Electronics (UK).
I made a big mistake buying a reconditioned 3.0 abb inverter from the uk. I completely forgot about them being on 50 hz. so is there any way to change it to 60 hz?
It may be possible, in the settings see if you can change the country and standard from g83(UK) to whatever applies in your region. I suspect that you can.
I haven't seen a way to change the frequency, however this may be in the engineering mode (requires code).
Hi HDLogic.
I already provided some comments on your interesting video a couple of months ago.
I finally got to repair the Aurora Power One inverter of my friend by replacing the defective relay.
We couldn't however test the the repaired inverter as my friend was keen to get a new one from another brand.
Nevertheless I got some thoughts after that.
As the Aurora inverter has 2 arrays but only being used in my case, could it be that the 4 relays are actually grouped by 2? In other words are 2 relays dedicated to Array1 and the 2 remaining ones to the 2nd array?
This could mean that having 1 relay being defective, one could simply disconnect the DC input cables from the defective array and reconnect them to the unused array !
Do you know whether or not my thoughts are correct?
I have tried your suggestion on other models, Solis, etc, and it did not work. I think during initialisation the inverter checks itself and reports back any faults, even if it is not using those parts.
@bootsowen thanks for your feedback. At least it's worth to give it à try as done in not even à minute.
A pity as well that these relais are not easily replaceable. Having each relay inserted onto a socket being welded itself to the board would have been a much more convenient way for reusing the Inverter and not trash it away.
Hi, thanks for your comment. I believe 2 relays are in series for the line (live) and the other 2 in series for the neutral, nothing to do with the DC arrays. The reason they are in series is for safety (so if the contacts of one relay were ever to weld on, the other relay would still disconnect).
Thanks a lot for this possible explanation. In case my Inverter is going to fail with an E031 error message, I'll however try to connect to the 2nd array. If it works, fine; otherwise I'll try to replace the relays.
I have a PVI-5000-OUTD-US/ SPR-5000P-TL-1 and I am having trouble changing it from 60hz to 50hz any advice?
Hi @David Brown! First of all, thanks for your comment! Unfortunately, your model of inverter isn't the one featured in the video, so being honest, I'm not too sure of the answer. However, I found what I could of the instruction manual, so hopefully you'll get some useful information there! hdtechlogicyt.page.link/Go5a
Thanks again for your support!
@@HDTechLogic thanks and I was able to change it using a RS485 module ,USB type b cable and my laptop.
Besides different firmware settings, US inverters often expect that each hot is 120V to ground (our normal residential services are 240V supplied on 2 120V hots that are 180° out of phase). Some inverters can be set to ignore this for where it is connected to a high leg or 240V floating delta 3 phase feed, but many can't. In any case, the frequency and other UL 1741SA defined parameters can't usually be changed.
How to fix error E033 ..??
Hi there - thanks for your comment. Having searched around online, it looks like the E033 error is caused by the inverter being under too much temperature load. Consider setting up a fan next to or near your inverter to keep it cool, and see if it makes a difference or fixes your issue.
