Thanks for the good advice I bought the same inverter and went ahead and put in the cap like you showed and it works great! so thanks again for the tip.
will be going in an rv. once the capacitor is hooked up, do you ground to the chassis? can you just hook the case ground to the thick negative black wire coming off the machine?
Yes you can bond the negative terminal and the case together and skip the capacitor if you like. It will let the fans operate like they should. Ive done this in addition to bo ding the AC neutral to ground without issue. All though there is no gfci protection, with those two bonds one can easily add a gfci extention cord as a feature.
Forgive my ignorance but I'd think connecting a large capacitor between the battery input battery and negative would be a good way to reduce EMF. Am I wrong?
going to try this on a 2000 watt power drive inverter I got for free. the guy said he got a puff of smoke, but it still works hot. no fans. I'll try this and let you know how it goes.
I have a different brand 1500 watt (modified sine wave). My fans do not work. My son bought it new and never used it. He gave it to me. I am the first to use it. It's about 5 years old and way out of any warranty. My thinking is to wire the fans directly to the off / on switch 12VDC. So when I turn the unit on, the fans are always on. Yes? No? and if no, why not? Thanks for the tips
Thats a solid plan yes. Not sure if the fan speed is load based or temperature based. Long as it has a way to cool. Nothing wrong with overcooling with an inverter.
If you add the cap and ground the case to your rv chassis, that basically defeats the capacitor bypass shorting it. Either the cap or bond the negative and case together will fix the fans.
so far it has been working out nicely for me I've only used it occasionally during power outages,camping and tailgating. I know for a fact that it will start up my refrigerator which is about 15 yrs old.
Centec,sorry I use the microphone on my cell phone and sometimes and it writes words I didn't actually say it thinks it hears something different so it's un telling what may pop up from time to time,,,,if you ever see one of my comments that doesn't look exactly kosher that's probably why,,,, it's actually caused me some embarrassing moments
Perfectly fine no problem I use the same exact method. I would not doubt that both inverters are made by the same Chinese company but they are simply marketed differently.
I am running a Whistler 3000 watt inverter (new). I am having an issue with chattering/clicking fans just like in your post. I installed the cap between ground (with looks like a chassis ground) and the NEG post. It didn't do anything. Can you advise a fix?
Couldn't find him...kinda new to this. How do I find him/connect? Also, I have a 2000 watt Whistler in for warranty repair...same issues with fans clicking/chatter. Well, they finally went out after only 3 months of 24/7 service. Whistler said those fans should not do that. Dunno it is a relay, circuitry, or the fans. But, it sucks that the .01 uF cap didn't work on my Whistler. Thanks again.
I am using my wfco wf5100 1000 watt inverter in my house.The inverter is plugged into a wall outlet and using house current until i turn of the breaker then it switches to the battery bank.The unit is mounted to the wall about 3 feet off of the floor the cables are 4' they are #2.The battery bank is 4 trojan t105 reading 12.9 volt under load.The load that i am running is a 32" lcd tv with dish network cable box and a dvd player.The total load is under 170 watts.The fan is always on even after i turn off the tv/dvr/dvd player.If it is load or temperature controlled can you tell me why when i turn off the inverter and just use the pass through of corse there is no fan.Help me under stand please.Possible fix.
Prince Gota if they are running full speed all the time, its hard to say. Could be a simple control circuit malfunction, or its sensing an overload. It may be thermally controlled or load controlled. Sometimes those thermal coupling sensors fail if it has that. You have the 3k tiger claw modified sine wave?
@@Bassguitarist1985 is that the little sencer that is mounted with a screw on the heat sink with 2 wires comming of it I got a 3000 watt BCI THAT THE FANS STAY ON LOAD OR NOT ITS PURE SINE WAVE ?
HI 2nd time posting this comment I have this osp tiger claw 1500w inverter the trace that connects the mosfets burned up. Could you please take a picture with the inverter connections + - terminals facing you looking on the left side of the board need heat sink removed that's where the trace is i need a picture of q 13 and the one next to it not q14. I can send pictures of what trace is burned if you give me an email .thank you
I have the same inverter. I followed your instruction and connected a capacitor but it didn't help. The capacitor actually lowered the voltage coming out of the inverter and when I plugged in a lamp, I noticed the light bulb started flickering. I just wonder what I did wrong check my video th-cam.com/video/f6TWzIMRZak/w-d-xo.html
I've seen this happen on my killawatt meter. No load it goes from 118vac to 115vac no load. Under load it drops to 110 at that outlets. Any less beyond the outlet indicates cabling loss and higher resistance. The cap is def good for the fans response. Unfortunately there is no way to internally adjust output voltage. The problem is that the boost stage is marginally sized for this inverter. Its more like a 1200-1300 watt inverter.
Thanks for the good advice I bought the same inverter and went ahead and put in the cap like you showed and it works great! so thanks again for the tip.
Glad it worked out for you!
just bought one of these because you had the fix for it
Thanks. I just got a new inverter. The fans are suppose to come on at 45C and turn off but they turn on way before and stay on. I may try this.
Bonnie Flory I think you will find this video beneficial for the use of your tiger claw inverter.
will be going in an rv. once the capacitor is hooked up, do you ground to the chassis? can you just hook the case ground to the thick negative black wire coming off the machine?

Thanks Doc Brown.😂Great video.

Zachary Stewart between earth ground and the negative battery terminal yes
Quick update, ive installed the capacitor internally so its protected inside the case.

Nice job
Glad it was helpful for you. Im sure it is for others!
if i add the capacitor is that enough? or do i also have to ground the case ?
If you add the cap and ground the case to your rv chassis, that basically defeats the capacitor bypass shorting it. Either the cap or bond the negative and case together will fix the fans.
how is that tigerclaw inverter working out and has anyone tried running a refrigerator with one of these Tiger Claw 1500 watt inverters 24/7
so far it has been working out nicely for me I've only used it occasionally during power outages,camping and tailgating. I know for a fact that it will start up my refrigerator which is about 15 yrs old.
Thanx
You know that tigerclaw does looking awful lot like my 1500 watt send text Harbor Freight they look very similar

This videos it’s from 2013 do you still have this inverter running?
Miguel Villa yessir I do! Though ive moved to an area with a much more stable grid so it has not gotton much use
Bassguitarist1985 thanks

The whistler is a modified sine wave, the cap mod wont work. Id suggest reaching out to ***** @knuas he has had some experience with this product.
OK thanks...appreciate it.

I'm going to put one of these inside a metal box. Should I isolate the inverter case from touching the box?
it depends on your application are you going to have the batteries isolated or is it a negative chassis ground

so you are saying zero watts load and the fan is still running?
LOL You MUST back up that entertainment center. Becauase if the SHTF you MUST be able to watch movies and play games!
Yessir! I have done just that! So worth it!
Smart move bro.
+Showemright YTchannel thank you! Inverter still going strong after all this time!
Hi my inverter 3000 watts keep going on never stop, do you know what is the problem?
I dont understand your question. What is the inverter doing?
The cooling fann never stop,do you know what's wrong with it.it using my batteries juice

@@jameswilsin5348 I beleive so, the fan control is temp controlled, not load controlled.

Thank you for watching. Apologies. I don't want to take the unit apart unless it needs servicing.
thanks alot!
Sounds like a bad design at least for the fans
