- Repair a Samil Solar River inverter with a disconnect / connect problem.
Ends up being the relays, but not a burnt contact, easy fix. This inverter had 7000 KwHrs on it so it obviously worked well enough and a little wear on the contacts threw up this problem.

Brilliant! Exactly the problem with my unit. After performing SAFE ISOLATION as any electrician should, I was able to repair my Samil TL3000 inverter using the technique shown in the video. 10 of my 16 panels were offline but now they are all running. Those tiny springs are scary though. I had to take extreme care to not lose them in the attic insulation. Thanks for the video.
Splendid, another unit repaired and saved from scrap. If your inverter is in the loft it needs an external fan blowing over the heat sink, controlled by a plug in time switch. Heat is the killer, cheers
Many thanks Andy. I had been sitting on this problem for a bit, and was about to call the electrician today when I saw your video. Had to take the unit off the wall to get access to the screws on the side of the switchboard. No fix after cleaning first relay, but joy after giving the second attention (cleaned contacts, closed space). Much appreciated all your tips. working like a gem.
Paul, brilliant, yet another inverter and wedge of cash saved. Check out my books and have you subscribed? cheers
You're a genius.. followed your advice. Left the inverter on the wall but was very careful to switch off both DC input and Ac output. Had no trouble removing or replacing the screws. Th clear plastic covers over the relays were a bit stubborn. I didn't remove the tiny springs in the relays for fear of losing them. I bent the contact closer together and used a points file to give the contacts a bit of a rub. Hasn't failed since...thanks for your efforts in putting this on youtube.

Lee, thanks for the comment and the appreciation, subscribed? cheers, Andy
Thank you so much Andy. Today my buddy and I were inspired by your video to repair my Samil Inverter, just the way you showed. My "Relay Failure" is gone and I am generating power again! And we had a ball! We were looking at throwing it out, but it is so satisfying to have fixed it ourselves. One hint - a pair of grips, opened wide, were ideal to easily take off the plastic relay covers. Many thanks!
Peter, that just grand and you had fun at the same time, if you want to share that feeling please see my paypal link, all the best cheers
Spot on! This was the fault at our relay failure problem. Thanks a lot!
Splendid news, hope you've subscribed for more interesting stuff, cheers
Thank you so much for your video.
My husband and I switched the mains power off and we fixed our inverter in an hour!
You saved us what could have been possibly thousands of dollars!! So appreciated Thank you!!
Hi, thanks for news update, brilliant another inverter saved, if you feel that empowered maybe you would like to share some of it with my Paypal link, subscribed? cheers
Your video gave me the gumption to try cleaning the relay/bending contacts as you mentioned. After isolating the "live system", I was able to pop the plastic relay lid (though the plastic catches at the bottom broke off). Five minutes later, the Solar River inverter (which has been down for months) was up and running. I couldn't believe how simple and effective that fix was. Thanks for making me look like a hero to my father in law. He had a quote for $300 for a technician just to turn up. Anyhow, I now have an order for a couple of the relays from Hong Kong in case the contacts get too corroded.
Nicholas, I doubt if that tech would have been able to fix it, but we have, please see my book "Wind and Solar Electricity". Subscribed? cheers
Hi, would you have a link to the replacement relays by any chance?
Can't believe this worked - huge thanks.
For me, it was the lower of the two relays that (probably) needed bending - there was sparking evidence in the transparent cover - but I did both of them anyway.
The system came straight back up - we'll see how long it's going to last.
I was actually hoping the relays might pull straight out and then I could push new ones back in.
Hi, thanks for your story, yet another inverter fixed and skills improved. I hope you have subscribed. Please see my video on extending the life of inverters, cheers
Thank-you so much for this video. One of my clients had a 'Relay Failure' fault on their Samil Power SR2K2TLA1 Inverter. I did precisely what you did here and up the unit came straight into Normal state. She had received quotes for AU$1,000's to replace the inverter, so she was very happy. I used a relay contact file and some 200 grit sandpaper to clean up the 4 terminals. I've subscribed too!
Brilliant another inverter saved from the scrap, please see my video on extending inverter life, good solid info, cheers
@@TheInfoworks
Will watch the video on how to extend the life for sure. 👍 Would you know the model number of those relays by any chance?
Wow , your Video is incredible . Thanks so much . My 2Kw Solar River Inverter is only 8 months outside the 5 year warranty and today threw up a "Relay Failure" fault log. It's total output to date is 16,465 KwHrs , ( installed 04/Feb/2014 )
Thanks to you , I've fixed the problem myself .
The contacts in BOTH RELAYS were really grubby and quite fried, so I carefully refaced them with an Automotive Points file and some 600 grit sandpaper to provide a good "Contact Point Surface" finish. I also slightly bent the points plate as you describe , to provide a small clearance between the end of the Electromagnet and the moving part which carries the actual points Here's a hint for the teeney weeney springs. Before you try to remove them , put a long loop of cotton through the eye at one end , then , when it pings of into no mans land , you just haul it back again aha.
Im so pleased you were able to assist. Regards Supaflee. NZ
Hi, thanks for the comment, there are ways to prevent failure, see my video on this subject to keep your inverter working for years, here's the link: ua-cam.com/video/GaqHZU8bD0M/v-deo.html, cheers
Andy,
Simple fix to an expensive problem. Love your work.
Paul, thanks, it was trial and error that brought me to this solution, cheers

My son and i repaired it like you instructed, Great and thanks for this video!
Hi, that is splendid, another saved from the scrap. I hope you have subscribed and looked at my paypal link, cheers
Just watched your video then Jethro Tull came on the radio....magick! ;) You've had quite a bit of luck fixing those inverters by sorting out the relays.
Hi, Songs from the wood, or Dahma. Experience with the eversolar taught me some of the symptoms and causes. Though I destroyed one of these units in the process. They fixes cannot all be that simple, but who would be bothered to spend a few hours tracking down the fault? Building a test rig helped significantly. Cheers, Andy
You my friend have just saved me £££’s thank you. Keep up the good work - Cheers!!
That's great news, please see my "book Wind and Solar electricity" cheers

Hi Andy, thanks, 3000TL relay failure solved after cleaning contacts.
Cheers
Thanks Andy, will give it a go and let you know the outcome.

Glen, I will be interested to hear how you get on, cheers
Andy you are the legend Mate thanks for the hint it works perfectly 👍😍🍀
splendid
Thanks Andy soooooo much, this allowed me to get my Inverter back up and running!!!!! Instead of having to call China from the UK
Dean, you are welcome. Please check out my books on my channel page (click my name). Cheers
Great work Andy, I have just fixed my inverter that has been giving me trouble for about 6 months, I had it off the wall, apart, fixed and all back together on the wall (and working) in 30 mins, even the wife commented on how quickly it was fixed 😀
Aaron, thanks for the message, perfect, yet another inverter and wedge of cash saved. Please check out my books (details on my channel page) and have you subscribed? cheers
So I found this 'fix' to only last a few months, then each time I fixed it it would be shorter and shorter between repair attempts.
This time I decided to replace the relays. I found them on eBay, and after pulling the unit apart, replacing the relays it has not missed a beat.
@@skitskatskallywag Hi, would you have a link to the relays you bought?
How did you get that board out? I tried but it won't move a mm. Almost like it has been glued on there.
@@deryk2002au sorry I never received a notification that you replied!
I just googled the code on the relay. Found them on eBay
Thanks mate works well now 👍
Cheers, hope you have subscribed.
Great in info seems to of worked on mine ok thanks
Brilliant, well done, Subscribed and liked? cheers
Hi and thanks for your video.
Do you know what is needed to use this inverter as an off grid set up? Thanks
Hi, that option is not possible as this type of inverter requires a high voltage input and the AC signal is taken from the grid connection. You need a battery based fixed voltage inverter. For a thorough grounding on all the choices see my Book (Wind and Solar Electricity, edition 3) Here's a link: store.cat.org.uk/collections/books/products/wind-solar-electricity-a-practical-diy-guide-3rd-rev, cheers
You my good sir just saved me from replacing my inverters and potentially rewiring the system. * raises my beer to you*
Hi, thanks for the comment and its brilliant that you repaired your unit. Have you considered subscribing, buying my books, or Patreon, cheers
Hi I have a solar river 1600tl and I want to replace the relays but I have already taken of the covers to clean them and I no longer have them do u know the model number of the relays so I can order 2 new ones
Hi, I'll get back to once I have a chance to look, were they clear like the ones shown in this video? Please give it a thumbs up, Cheers
Hey Andy. I found 1 of these on somebodys clean up pile yesterday. Similar problem. Broken solder joint on the same area. Could I feed solar into this & get AC out? I'm hoping! Cheers. 👍
Yes, you would need at least 120 volts DC, so 4 panels minimum, so the label and my book, cheers
If only they were that easy to fix Lol, what pointed you in that direction in the 1st instance? Good job good fix Andy
Hi, experience with the eversolar units and the fact that there was a faint buzz from the relay area. I know from experience that contactors will buzz if there is a problem with either the contacts or contaminated laminations. Cheers
Andy Reynolds Thanks for reply your experiences shared are most valuable
Hi Andy, I have Samil Power Solar Lake 5500TL-PM that's not working. The fault code is no. 79 relay error unrecover. As far as I can see the fault codes only go up to 61, is this correct. The inverter was replaced under warranty about 3 years ago as it had the same fault. Its a three phase system. I very much look forward to hearing from and would greatly appreciate your help. Many thanks. Tim
Hi, if it is a relay fault then follow the video and make sure the contacts are making good, but also check the relay solder joints as shown in my Aurora E031 repair video. Looks like you need to get the tools out and investigate unless it is still under warrantee. Heat is a big problem with inverters see my video on extending inverter life, maybe your inverter is mounted in the wrong place, cheers
Hi where are the relays in a 1600TL?????
Hello do you know how to change AC voltage? To for example 255 V
Hi, the grid inverter will work to the line voltage, so it does it for you, cheers
Hi Andy, do you know if the solar lake inverters use the same type of relays? I have a customer with a TL12000 that won't boot up.
Hi, the relay fault is shown when the inverter goes through the boot up process. If there is no life then look elswhere, is the DC getting to the inverter? or is there a fulty connection somewhere, best have the front off, but a 12 Kw will probably be 3 phase so be careful, cheers
@@TheInfoworks Yes it's 3 phase and there is dc getting to it. It's not showing a fault code. The fan kicks in when it has timed down and there are a few relay clicking noises but then it just goes back to timer mode.
Difficult, usually you would get something that identifies relay fault, but hey-ho, the first option is to clean and check the relay contacts, cheers
I had a similar message on my SolarRilver 1600TL. Unfortunately my relays are all compact types and it's not possible to see inside them. Initially I thought there were a load of relays, but judging by the circuit board silk screen, some are actually square caps. I think I will remove the main board and replace the 4 relays I can identify to see if that fixes it... I'm not sure how I can test if they're working in place without risking blowing something up. Why they can't make the relays plug-in replaceable, who can say...
On a Aurora inverter I have removed the relay covers with a dremel, that helps with covers that are glued, cheers
Does the whole relay come of or do u have to replace the hold board
Hi, if you watch the whole video you will see it's a relay contact reset. No parts required. Watch it 10 times and see my Paypal donate, cheers
Andy, I love it when individuals like you sort stuff out that manufacturers get wrong or fail to put right. MY Samil Solar River 4000TL-D has just stopped outputting data via the LAN port. Any suggestions? Thanks.
Hi, is there a battery for the data storage? maybe that's first place to look, or maybe a duff cable or socket, cheers
@@TheInfoworks Thanks for your reply. An Italian service engineer diagnosed an issue with the Firewall not letting data through. I guess my latest Avast update screwed this up. All sorted now.
How things get more complicated, that's something to remember, subscribed? cheers
Hello. On the internet I came across your video regarding inverter repair. I have Samil Solar 3000. I bought a used 10900Kwh, problem for 3 days - relay failure is displayed. I took off the cover, after starting the spark the upper relay. I will start cleaning tomorrow. I have a question for you, is this just a contact problem or has the relay solenoid lost its magnetic value? Best regards and good health.
Hi, it just a contact problem, the relay coils retain no magnetism but create it when the coils are energised. They either work or don't and when they don't it is either a fault in the coil or the circuit that feeds it, cheers
Turn around the pcb to dissolder the old relay and solder the new one on.
Hi, yes that's a solution but this inverter is still working 6 years later, cheers
Hi andy
The inverter goes in error OVR
So here in Holland it means that it goes over 253 volts so i read that it can higher if i raised it bij 2 or 3 volts the system wont stop anymore
Greets frank
Frank, I looked at the display on my 2300TL hoping to find a service section but to no success. They are often password protected but often just pressing enter works. Other inverters have such a section but I have no experience with max voltage adjustment. 253 sounds quite high, is this just on very sunny days where all the PV systems are raising the local grid voltage? cheers
Hi Frank, i have the same problem in the Netherlands. OVR errors. Converter stops at 240volts. Thats to early. Dit you find a solution to raise it some volts?
I need a good inverter at a good price. do you have any idea where I can get a good inverter? used. as long as it works good. 24v 60hz. 120v. have any idea?
or even a 48v or 12 v . but it needs yo be 2500-3000w give or take. but I would like a 5k+ if I could afford it. thanks. I learn a lot from your videos
HI, I would look at Victron, steca, outback, or mastervolt. 110v and 60 Hz means you are not in the UK, so I don't know, try Ebay or similar. Cheers
Fault has returned and now the relay is definately broken. I would like to replace this specific relay but the board is very tight to the cooling element. It almost looks like it has been glued. Any advice on how to get this board of? I need to
Hi, that's a shame, were you gentle with the relay? undo all the screws and it should lift out. There will be insulators on the FETs, cheers
That was an easy fix Andy ! Are these boards using Chinese made relays do you think ? Having to bend a contact like that is pretty poor really. I've never known a relay fail like that personally !!
The case screw holes being so misaligned isn't great either - I wonder if they have a piece of wood and a g-cramp on the production line :o))) Another inverter working again anyway. whic is good. Dave
Dave, thanks for the questions, yes they are Zong Chuan, 15 amp. The contact size is great and this inverter has 7000 KwHrs on it, so it worked well for quite some time. One never knows what system it was fitted to, and how many panels. Some installers push inverters too hard and the customer looses on durability. The fix seems to have increased pessure on the contacts to good effect. The case cover is only a problem due to the postition of the screws, the problem being that the seal needs to be compressed. Most inverters the cover is pulled down onto the seal from the front. It's always good to have a few spare units, but because I don't run mine anywhere near their rated power then this spare may well stay where it is. Cheers, Andy
The relays might have been soldered to the pcb in a way that softened the plastic and the contacts moved a bit in fairness to the relay maker. As you say, those have done some time without failure already. The case has a seal to compress....ahhh I see, as you say, screwing from the front would have got around that problem. Dave
Hi Andy, I wonder if you can help... moved in to a house with a PV installation already there. I have a Solar River 1100TL. The other morning I noticed an error code "EEPROM Failure" on the display. Searched the web and it suggested to disconnect PV + and - from DC. So I turned the DC Isolator off and back on after a few seconds. The inverter restarted and normal state resumed. However, I've had to do the same thing again this morning. Do you know how I can permanently fix this? I don't want to be having to go under the stairs every morning to restart the inverter.
Also, the inverter is now reading a etotal of 9658kwh on its display but my meter is reading 9522kwh ? Is this right?? I'm concerned where it's been in error mode it's not relayed the correct readings back to my meter?
Hi, some of these errors can be difficult to find. First you should always disconnect the AC before the DC to prevent relay and contact damage. Second I would go through all the connections both AC and DC to to catch any poor contact. Third improve the cooling of your inverter, heat is a major problem and it's very sunny at the moment. Experiment with this and see my video on extending inverter life. Latterly, put a search on Ebay for a spare inverter. It seems the difference between inverter E total and the fits meter is not that great so don't worry about it and see if you can solve the primary problem as the system will not generate with a fault. Subscribed? Cheers
@@TheInfoworks just subscribed. Thanks for the quick reply. I just went and checked it again and the error was up again so it seems to be getting more frequent. Does the inverter need to be opened to check the AC and DC connections? Sorry it that's a stupid question I have little to no knowledge. Although the inverter is under the stairs it does have quite a bit of space around it to reduce any heat build up. Is there any way I can send you a picture of the set up so you could explain a little further? Kind regards
Hi, I'm talking here about external AC and DC wiring. How many panels are connected to this inverter? Heat is a problem so an experiment with a fan and time switch may help, see my video on this, you can load a short video (or series of photos) on your channel showing the scenario, cheers
Just a note regarding the relay, they are a SCL-1-H-DPNO relay by Song Chuan. The 'H' in the model name denotes the contact gap to be 2mm so if you have this fault and decide to clean the contacts, don't forget to set the 2mm gap afterward. This gap is measured between the underside of the contact arm points and the middle prongs of the relay when facing the Samil unit on the wall.

I can't get the blue top off. Can you help????
Hi, there are 3 screws each side, if it is still difficult after these are removed then warm the edges up with a hair drier to soften the seals. There may be 2 screws under security stickers. cheers
Great video. I have a Samil River 4000 TL-20 took the screws ok of the sides and top, but the cover refuses to come off even with considerable effort with punches etc.. moves half a screwhole but no further.I was wondering if the seal is stuck and how to unstick it?
Anthony, hi, I'm not familiar with the 400 TL but if you are sure all the fixings are removed then maybe the seal has gone hard, try a hot air gun and a bit of educated violence, good luck, cheers
Sorry should have read the whole thread! the answer was further down. Used hot air and it eventually sucumbed, but was very well stuck down with sealant. Got the model no wrong it was of course a SR4k4TLA1. completely different inside to yours though. My problem was input AC voltage underrange fault voltage and reading 104 volts with the mains input at 245 volts.Nothing obviously faulty to look at. Input AC fuse OK. Could really do with a circuit diagram to go much further though. but suspect its a very heavy paperweight.
On further investigation took the pcb out ( a lot of screws holding it down) and found the problem on the solder side. Burnt out solder connections to the AC linefilter inductors. Looks like bad solder joints from manufacture. Cleaned them up and resoldered properly including some other suspect solder joints.
Hopefully it will all work, just have to wait for the sun now!
Anthony, that's great news and brilliant persistence. Good info as I have several inverters that cannot sense the mains. Further investigation required. It's that lead free solder up to it's tricks again, cheers
@@TheInfoworks It looked like the inductor enameled wires were not properly de-enamelled before solderflowing so the solder could not get down the through holes resulting in a dry joint. The units are easier to work with than I first thought.
I have this inverter, after 9 years the led screen says "no utility" can this be repaired or do i need a new inverter? Thanks
Hi, I assume you have checked that AC is getting to your inverter and that all fuses and trips are all OK. There is a fuse in the inverter and you will have to take the cover off to access it, and it is here that you can check that the AC is available inside. Be careful, subscribed? cheers
@@TheInfoworks yes I have checked all that which is ok, I don't know what causes this no utility error from the inverter so not sure if it can be repaired or if I have to replace it. Thanks. Subscribed
Hi, in that case it will probably be in the AC sensor circuit and I have never had any success with this, there are Solar River inverters on Ebay, otherwise I suggest Solis. It's heat that does the most damage, cheers.
Hi my friend
I have the same issue saying relay failure.
And I was figuring out the relays but couldn’t find them after seeing the video. So I need a little help can you please help me with this. Otherwise It will cost me a lot of money If you know what I mean. Waiting for your reply my friend
Hi, what model is it? the relays are sometimes in different parts of the board and may be white or black, they will be there and the tops may be more difficult to remove,. On the auroras I have to use a dremel to cut the tops off, cheers
Andy Reynolds Thanks for the reply mate. The model is SOLARRIVER 1600TL and I think the relay are in black colour. But the thing is I don’t know even a thing about this I could have called you If I had your number. That would have been easy for me. Could you please give me your number and few minutes from your schedule which could really help me saving some good money. Cheers waiting for your reply
No they r long skinny black one's
Rick, these soumd like the same units as used in the eversolar inverter I fixed where I fitted larger relays. The original relays were Song Chuan, DPDT (dual pole dual throw) 894 2CHA2 - F- C.
