Samlex SSW-2000 Pure Sine Power Inverter Repair: Part 5

Finally had a break through and was able to repair the unit. Samlex provided me with the main PCB schematics, and a new updated input drive circuitry daughter board. It was an updated design and more reliable. I changed out all the input FETs with some quality International Rectifier brand, and input caps to Nichicon brand with a higher voltage rating. A few drive transistors burnt/shorted and replaced those.
This is my first attempt at repairing an inverter. I learned a lot. Next time an inverter fails i will have more background to fix it quicker.

A Kill-A-Watt is the best tool for measuring actual power from a 120 volt inverter. I have a solar-charged 420AH 12 volt battery bank with a 2000 watt pure sine wave inverter as my "Wait until daylight" solar generator. Depending on the season. it can provide 8 to 24 hours of limited power without me going outside in the dark, a thunderstorm or 30F and 7 inches of snow to start a gasoline generator. As most of our outages are less than 12 hours (longest at this location in almost 15 years is 16 hours), 8+ hours should get me to better conditions for starting a gas gen. Although there's a volts/amps/watts/AH meter in line with the battery bank, I always feed the transfer panel via a Kill-A-Watt so I'll know how much AC power has been delivered, as well as the DC power used to produce it (verifying inverter efficiency). Having the DC meter also ensures that the battery bank gets an adequate recharge (typically 110% to 115% of the discharge AH). The inverter is from Reliable Electric and idles at 1.2 amps below 13.2 volts input and 0.7 amps above 13.2 volts. Other than the brief (1-2 seconds) run at power on, the fans only run when the inverter is hot. I also have a second identical inverter as a spare and a 500 watt pure sine wave inverter if needed for fallback (powering communications [phone, internet, cable] or charging power tool batteries but not running the fridge or furnace).

[@dkeithtag]

My compliments to you! What essentially happened was that you corrected a design flaw with the lo-v driver circuitry after dealing with some heavy cascading collateral damage. Would be interesting to look at the manufacturers' failure data. In all likelihood had nyou replaced the defective component with an identical (read discontinued) part, the failure could probably have recurred. Again, great work!

[@Nodularguy1]

You know it was fixed correctly when you say "Holy Fucking shit" ! HAHAHA ! That's the exclamation of self doubt leaving as you confidence on the repair was in doubt. Bravo sir !

[@Bassguitarist1985]

yeah this repair was kicking my ass for over a month. Couldnt have done it without Samlex kicking in the daughter board!

[@Nodularguy1]

Great Job. I know the feeling of turning the corner to finally see you climbed the mountain. You're videos on the Generac generators helped me fix my fathers set and saved him big bucks. Keep up the good work and vids.

[@Bassguitarist1985]

Jeff Barr hey Jeff. Thanks for the kudos! Yeah this inverter was a steep learning curve for sure! Glad my gen videos helped you!

[@milvolts1]

By far best detail oriented and insightful video for a power inverter short I have seen so far. You should be proud of your work. I have a situation with a fairly new 1500 watt PSW inverter. Sorry for my long violin question. if you read through it I would greatly appreciate it. if not, well I would understand. Here we go..I shorted something out trying to add an additional external 9mm on off switch for my solar power box, so that I would be able to turn on and off without having to open the cover to do so. Anyway, my mistake was to wire the positive lead of new switch to positive lead of inverter switch, and here is were my bone headedness began, I put a negative lead on new switch and wired it to a spliced negative lead that was going to the volt meter. when I powered the inverter on I heard a crack and saw some white smoke coming from the area of the 2 output capacitors. The inverter was dead no power .So I took the inverter apart and to my surprise both capacitors were fine. I did noticed a trace had protruded the board and was slightly charred. I resoldered the trace and got good continuity again. To my surprise the unit powered on. but then quickly went to fault mode. I'm in need of some advice and hopefully you can shed some insight as to what the problem is. Thanks

[@Bassguitarist1985]

Hard to tell without some sort of schematic, but the cost of repair may outweigh a cost of a new unit sadly.

[@chikiguites]

Congratulation my friend I dude that you can resolve that amezing problem, but you have a lot of persistence or resilence or wherever they say... i mean Rosevelt, Do wherever you do whit the things that you have! I had the same problem whit inverter 4000 in peak 2000 continuos i changed all the mosfet of the A.C line but ringing alarm have a another one burned mosfet in the tablet same as yours!

[@chikiguites]

This is the price of the perceverans... You won my fried, but I m still working whit my inverter 4000 watts! this dosnt has any burn it in aperance thas why i m look at the damages it is harder!

Love your video series on this. Outstanding job of being tenatious on finding the solution. I have an inverter with blown mofets also. Now I'm not so eager beaver to get into it after your vid. Just a thought though, and don't take it wrong please. I used to cuss so bad I could make a sailor blush. Like a drunk to a bottle I'm drawn to cussing and fight it each day. Then I had children and didn't want them to go the same road I took in life. My twelve year old watched the same video with me . I'm getting him excited about fixing electronic components on his own. I'm trying to encourage him to fix versus the 'Oh well, it's broke and toss mentality' which is not good for the planet. So please, for your young fans sake, try to edit out the cuss words. Again, don't take it wrong, I'm just trying to expose my twelve year to what is good and you have enriched us by your knowledge. Thank you sir, and best wishes.

@@Bassguitarist1985 Too bad. Thank you anyway.

[@milankoondricek3374]

You were lucky to get it work again ;) For the next time, and for all those not very skilled ones, you never test anything by plugging it to the battery without making sure everything is fine ;) You have to check every stage, that it is working, first the controlling board, you need oscilloscope to make sure all the primary mosfets are getting correct impulses, then you can connect a limited current power supply to see, if everything else is OK at the primary side of the DC/DC converter...but you were also lucky, because it is sometimes more difficult to repair the output stage, because of the high voltages present, and burnt mosfets usually take their controlling IC's with them...but again, you have to make sure first, that the control board generates correct impulses before connecting the mosfets to power, otherwise you risk burning all of it again ;) I was laughing a lot not at the famous sentence - holy shit, it works, but when you burnt those primary mosfets again due to lack of checking those impulses from the control board :) But well done, next time you don't have to waste time at the output stage, when those mosfets are OK, and if you check everything as I said, step by step, you save more time and money because you don't burn anything anymore ;)

[@Bassguitarist1985]

Thank you! Yeah it was my first inverter i fixed. Learned a lot from the experience! Lol didnt know that my comment was a famous one! I was genuinly shocked it worked after the struggle!!

[@ajw6715]

Your input fault was do to the missing caps. It could not work without them.

correct

[@Bassguitarist1985]

***** I was able to fix the unit!

[@ThatGuyKappa]

bravo!

[@z1power]

That remote will probably be more accurate at higher draws. At lower draws there is very little voltage across the current sense resistor/transformer so its more difficult to measure.

[@dr.decalin5565]

I have two dead inverters, so now I have some technical ammunition to attack them with. Many thanks! I admire your tenacity.

Carnage like that is almost always a bad capacitor, not poor components. My experience with Samlex support parallels yours.

[@stuie25]

I do off grid cabins and solar and we have lots of issues with the new samlex inverters, most get sent back but i did one a few weeks ago that was out of warranty a 1500 pure sine the newer style. I did attempt to check the fets but a quick overview got me nowhere, i just just a constant overload light and alarm.

[@StuffBudDuz]

Really cool of Samlex to send you the schematic (not to mention the daughter board!). I have a failed PowerBright that is now a paperweight after 40 uses. When I wrote them for the schematic they told me it was "proprietary" then offered to repair the unit for me if I paid for the repair and all shipping charges, which would have amounted to more than a used unit on Craigslist. I will not buy PowerBright again. May try Samlex this time. I love a company that supports their products! Thank you for sharing this. Great info!

[@Bassguitarist1985]

+JillettProductions Yes Samlex I would highly recommend! Good support, and the build quality is good for the price.

[@vincecatania2463]

Really enjoy your detailed videos on inverter repair------I have a Xantrex XPower 1750 inverter that when opened looks absolutely pristine although when it is 12 v powered it does not function.------the fuses check OK and there is no evidence of excessive heat anywhere. Will the application of reversed voltage blow fets without visible damage?

[@Bassguitarist1985]

yes

[@errolwoodhouse6605]

Enjoy your video thanks.

[@JamesLewis]

I have to say I would have added heat transfer compound to all the FET's...

[@Bassguitarist1985]

In retrospect yes I should have. The next inverter project ill know better to!

[@patodonnell2438]

Would you still have the schematic for this unit? I have the exact model.the output voltage is only 115 volts under 100 watt load

[@Bassguitarist1985]

Its archived somewhere on my old computer. 115vac is acceptable though

[@igor1126]

Very nice project. I have the same inverter, and my fans kick on as soon as i turn switch on, even without any load. Ones i have some load, fan will speed up. I thought this inverter has temp sensor, not amp sensor to start fan. What do you think?

[@Bassguitarist1985]

Yes I agree there should be a temperature sensor not a current sensor

[@fosterraymond]

very good work, but your video didn't show the schematic during the troubleshooting is it available?

[@Bassguitarist1985]

I have the schematic of the main circuit board but the daughter boards do not have schematics and are not available from Samlex...at least they were not willing to give it to me.

[@danielwoo4246]

Excellent repair work with good logical procedures. I would test the input driver board to make sure that there are driver pause signals generated from the board while the board is out of the main board with my scope first.

[@Bassguitarist1985]

Thank you for the info. The input driver board was actually where the problem was. Unfortunately the design had changed and was no longer available. This video series was taken when I was first learning about advanced electronics like this.

[@andrewjohansen2444]

Great video , I watched all five . In your opinion, is there any thing that could have prevented this problem? I have been looking at this inverter for my rv , and would hate to have this happen . you said that there was a fuse before the inverter, could a faster burning fuse help?

[@Bassguitarist1985]

a proper sized fuse on the positive cable is for safety so the bats don't explode. A failure like this was due to bad components.

[@aterack833]

that new daughter board looks to be the heavy duty version, likely for a higher wattage or because the old one was under powered for the job

[@Bassguitarist1985]

+aterack833 agreed!

[@DimitriPappas]

Great job. I may be wrong but you'll probably find that the on-board watt-meter will be closer to accurate at higher draw loads, say above 300w?

[@Bassguitarist1985]

Possibly. If you notice the remote is numbers for watts while the newer ones sold today is a bar graph. It may not have needed to be as accurate down to the number being the output was a bar graph. Another point to note is the newer input daughter board was not meant to work with the older remote DrBlackrose told me the remote doesnt operate the inverter to turn off/on anymore, but obviously outputs the info. Battery voltage is accurate. I think its because of incompatability with the new daughter board and old style remote. Either that or maybe an SMD transistor blew on the remote daughter board that sends a signal to the drive daughter board to turn on the inverter either way im happy it works again. Learned a lot!

[@garyhoerner8233]

I have heard that the watt meter on the remote will show after the first 100 watts, meaning, add 100 watts to the value to get the correct wattage

[@stoatrepublic]

Very steep L-Curve, learnt a lot from this series. What I like to do is put. A automotive bulb in series, bright bulb indicates short and dim bulb indicates that bulb not needed. Thanks for publishing this.

[@Bassguitarist1985]

Take it apart, look for blown fuses and burnt components where the magic smoke released. Even if a component didnt burn it may have likely shorted or failed open. Good luck!

[@jamesrussellnix3]

On the last video I was thinking, don't stop now you've rebuilt the whole thing almost lol. Bravo!

[@Awynn0]

So you plug in what you said yourself to be 70W of lights and a LED work light at maybe a couple of Watts and complain it's not accurate when it shows 70W on the output power display........ um seems pretty accurate to me?? It may well have been pulling more than 70W from the DC supply, that's called not being 100% efficient, especially at low loads like that!

[@Bassguitarist1985]

+Awynn0 i switched to a 100 watt incandescent bulb and 70 watt rope light for the test. Yes this inverter depending on load claims to be 85-90% efficient. I've measured it to be in the mid 80's efficient with various loads.

[@Awynn0]

+xboxer1985, you didn't say you changed the light at the time so I missed it but now I look back I see it actually is a filament bulb and in fact the LED one is just in shot on the floor there. Yeah I have to agree then, indicating somewhere in the region of 100W less than the expected load is way off...

[@Bassguitarist1985]

Yeah my fault I didn't mention the changeover to the filament bulb. Its def because of the new driver board. I'm sure if you pared the new driver board with the newer style bar graph remote it would work just fine

[@davidw2425]

great video series

[@Sonikbytes]

Good job! I have to fix my Xantrex prowatt sw 2000 sine wave which is very similar in quality to yours. Why they blow up just as easily as the Chinese ones? This is what I have done which I learned from your great video: checked the DC side seems ok (no blown transistor/fets) cant test the drive logic yet On AC side: had blown ICBT replaced with similar one (ordered from China) Just discovered the gate 10ohm resistor open. (do they limit the gate drive current) could that be the problem of fatal failure? A resistor burned in the power stage that powers the driver logic to output daughter board AC side I dont know what value to replace with :( any help would appreciated

[@Bassguitarist1985]

+ElenaDiakova drive resistor blown means the drive circuitry kept that bank of fets on too long. Likely something shorted on its end pulling the fets to ground for too long and the resistor burned. Replace any blown driver Fets and predriver NPN transistors, then concentrate on the drive circuitry for the DC side. There is a likely failure there that cascaded to the the drive FETS.

I have two yellow top optimas. one is a little older then the other (shame on me I know) and it does feed off the new one a little bit. but I still get a good 14.5 v charge while engine running. just to try it out out quick I used a set of 4 gauge jumper cables.(not the best idea). didn't have a voltage drop at all. but im going to set up some 2 gauge 1 foot long cables and see if that works soon but not getting my hopes up.
