Where did you buy those replacement relays?

Nice work…yeah common fault on the Aurora’s. Capacitors sometimes go as well. And yes, inverters are usually powered up by the DC side. Nice job dad 👍

do you know what causes E033 error? The converter is in Arizona, it is definitely not overcooled.

Where is this?

many thanks for sharing - I had the same fault and could fix it thanks to your video :-)

Great video - apologies for the dumb question but at 27:02 you mention about jumpering the wire between the track, but from what I can see is that you are jumpering between one relay and another. How can you identify this is on the same track?

So glad that someone filmed it!

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

Hi, what can i do about error e034?

Helpful videos, thanks. Having now dealt with our E031, I can feed back a few things to make this job easier. First is that disconnecting the grid cable at the PCB will make handling the PCB thereafter much easier. Secondly, it is much easier to lay the unit on it's front when removing the backplate and mounting brackets. Then, without repositioning the unit, you can pivot the inner metal backplate up to remove the ribbon cable, and then keep pivoting it over to almost 180 degrees, and you will find that the inner backplate will sit nicely in this position making it really easy to remove the remaining cables, and then the PCB. Finally, if we consider that the output, or product of this unit is is mains power, then it is logical that it must receive it's own operating power from elsewhere. Note that part of the start up process is to check for the presence of the grid, and this check would not be possible (or would be redundant) if the operating power to do so was coming from the grid.

Thanks so much for the video. Failed after 6 years was quoted $1200 Australian to replace. Fixed it with your help for $30.

I think this is a hydraulic lift so this is why its rather slow... It sounds quite nice IMO though...

Incredible stuff!!!

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!

The failure is not the PCB, but the relay contacts going high resistance which then is causing the overheating.

finally new content!!!!!!!

How to fix error E033 ..??

Rather scary picking up the whole PCB by a relay that is almost completely unsoldered. Good way to rip a track off the PCB. Also your inverter is not going to turn on without DC present from the solar panels!

nice if you can list relay part and where you got it

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?

This is really useful - thank you. Will there be any issues having the Aurora reset after such jobs - will it affect built-in readings or info which is required for FITs, for example? Thanks.

can you change the hz. from 50 to 60 hz. in this incerter?????

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?

Great tutorial. Now the goal posts have changed on renewable, can you recommend a battery storage solution to tie into this at all please, keep up the great work, Thanks.

Do you have the Service Code to get in deeper menu? i have the aurora pvi 3.0

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 just repaired my Aurora thanks to you and this video! Thanks for sharing this precious knowledge! Warm regards!

Do you have the total wattage, or amperage? I have an issue with the same model. Thanks for posting this gents

Our inverter stopped working after 6+ years were quoted £1200 for replacement so searches the net for answers and found your KZbin video we followed your instructions and low and behold exactly the same issue all now fixed and working fine we are very grateful for your video's saved us a lot of money and only took us about an hour to do.

hi .. my power-one say E011 error ... what can i do?

Very nice to see an 80s lift with relay logic. That’s the decade when relay logics were being phased out and lifts ran on computerised logics

Hi, where did you source the relays from. Thanks.

These relays are two pairs in series doing the grid disconnect, one pair on the Live side the other on the Neutral. One side of each pair of coils is commoned, the other side are driven by two different parts of the control circuits. Not sure why they designed it that way. Has anyone been able to find a schematic for these units? I've looked for a circuit diagram but not found one online

I have posted on one of Andy's videos, that Hongfa HF165FD/12-HY1TF relays are the same spec... and are available from Rapidonline for £1.81 Inc VAT each.

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

Hello, 3000 watt solartronics full sinus inverter fault light is on. When the inverter is turned on, a relay tripping sound is heard, then the fault light is on, what do you think could be the problem?

Thank you. Changed 3 relays which had obvious issues with the solder joints Added extra wiring as you suggested Connected the two solar strings and ac. No more E031 error codes and generating electricity as before. Only difficulty was removing the relays after desoldering. One coil connection had not been fully desoldered and the fine track lifted as I was jiggling it about. Fortunately the track did not break . Just want others to be aware to use a good solder sucker and solder braid Once again many thanks

Many thanks for making this video. My Aurora power one inverter failed after ten years in exactly the way you describe. I ordered the four relays via eBay from a very helpful company in Axminster, and they arrived within 24 hours. My inverter Is now repaired, and back to exporting to the grid. The only extra thing I had to do was reset the inverter clock, also described elsewhere on KZbin. Thanks again guys

Hello, I have the same inverter that is ten years old that no longer works I have no faults the solar panels supply dc 230 volts but I have no watts coming out it lights up in the morning and goes out in the morning evening without production do you have an idea of ​​the breakdown, thank you. I'm French sorry for the translation google.

Really nice and thank you for this awesome vedio, issue resolved

Hi Gents. Fantastic video. Thanks for taking the time to make it. Really helpful for a novice like me. My Aurora inverter has just shown the E031 error after 11 years of trouble free use. Opened it up and only one of my relays has overheated. So bad though that it burnt off the green solder mask or about 1cm at one pin. What size wire did you use for the jumpers?

Thank You so much I m very annoyed by watching different videos to install, none Of them worked.But after watching this video all I m so happy and relaxed that finally i get the method how to install. 😁

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, Thanks for the reference, my series of videos all come from just wanting to know because this is a very common problem. Put it back in the loft, there's your problem, heat. I have a video about extending inverter life, cheers

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 mate Great video. Mines gone too. I have ordered relays. Soldering iron and tools needed. Only thing I haven’t got is the jump wire. Do you think it is entirely necessary to jump?also a tad confused on positioning on cable on both sides of pcb

Great 👍

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.
