1500 watt COTEK

[conntaxman]

Dose anyone have a "Cotek SK1500-124 1500W Pure Sine Wave", I have a chance of getting one for $200.00 .Its 24vdc. Many have told me that the 24volt is better then the 12. Because of wire size and draw on batteries. I know the back has the input for the 24volt , but never did see the front yet. I asked him to send a pic of the front ,to see how many plugs it has. The back has 2 BX connectors. so im thinking that it is a hard wired version.
My main concern is how good are they.

I have the 48V 3000W model. While I haven't had it running for very long, the power it puts out is cleaner than what I get from the utility and all of my AC motor loads start at least as well as they do plugged into POCO power.

tks also.,Im also looking at the rayson sun, 1500, this would be new, and 1yr. war. for only about 40 dollars more.

So how many plugs are there and what are their amp and voltage rating on that inverter?

Cotex/Samlex/Meanwell from Taiwan all have a variety of plugs for different world applications. GFCI is the way to go here. The higher priced Cotex is UL listed, samlex and meanwell only UL compliant.

He only showed the back of the unit.I told him to send a pic of the front. Don't know why he didn't show the front along with the back and side. humm , It's 1500 watt P.S. inverter

Thats why i go with the new one and pay that little bit more.

I found quite a few of them for sale with different configurations and output receptacles. They were all in the $400 to $500 range so the one for $200 sounds pretty good if it works and has the desired receptacle on it.

Mine has a hard wire option and the ability to switch from 50/60 Hz with a DIP switch, I don't know if they all do though. I have mine hard wired but it still has the US GFCI outlet right next to the hard wire spot. The GFCI oulet is in a removable plate which, I assume, they have country specific plates they use on the inverter because the wires are all inside that compartment. Looks like they just swap in the correct plate and hook up the wires to me.

Yes, I read the manuals on all three (Cotek/Samlex/Meanwell), all have similar specs and all have the multiple outlet configurations for anywhere in the world. Fairly versatile design with 50/60Hz AND 110/115/120vac option.
I chose a small Meanwell, much cheaper but only UL compliant, good lil 400W true sine for $168 delivered. Meanwell also has a longer warranty, 3 years.... tho who knows how that would work. Bought from a midwest USA marine supply retailer but never asked if it could be returned there.

Which brings to mind a question I had.... Why the adjustable VAC output?? They come set at 110VAC but I figgered 120VAC would be better to run 100ft thru a 10AWG extention cord.

I know for the $200. it dose sound good. and they are more efficent then the 12vdc ones,and the batteries don't take such a hard hit, with the amps draw.

FS, if mine has adjustable VAC ranges then I don't know about it yet, there are more DIP switches on it which I have not yet investigated though. Mine measured 120.

This one also has 2 BX connecters in the back along with the 24vdc input.
this sure dose help and make one feel better, knowing some have it and its working.
I think that the guys here were right when they say a 24 volt one and higher are better the the 12vdc ones.I could see the Less draw on the batteries, but if you wanted to use it else were, your kind of stuck.lol

I was looking at that model. I ended up buying a Samlex 2000w (24v) pure sine which I think is pretty close to the same thing. I have had it for 6 or 7 weeks and has worked great. I don't have testing capabilities but I notice no difference between it and grid power. TV looks great, fridge runs fine, modems and wifi fine, and most important ham radios all fine. Have not yet had any problems whatsoever.

I'm no expert but for $200, I would try it.

[Cal Dan]

Also, they have pics online of the front but mine has hard wired and 2 plugs. It should be the same.
