I'm starting this new post for any newbie that may want to build a control board for a power jack or homemade inverter I've read that all the components values are on the boards so it's almost like paint by number there's so many versions and so many updates it very confusing to a newbie I was hoping that all the experts on here my comment on the best control board That would be easy for a newbie to solder together I'm new and the problems I'm having is getting a complete updated parts list getting the pcb board Or the right CAD file to send to pcbway or similar companies to have them made be warned i am good parrot but Dumber than a box of rocks |

Poida has given you the mods he does to the egs002 control cards. I would personally run with that if your machine currently runs egs002 cards. Cheers Caveman Mark Off grid eastern Melb |

Thanks renewableMark So you are saying that's just as good as any other that clears a lot of things up if so and makes things a lot simpler when you're new and read so many different things you don't know what to do I know poida is alsome really intelligent and wise didn't want to bug him to death you and warpspeed have been really good to me also renewablemark you have given very good advice that I trust and will definitely take thanks again I just didn't know if that was the best fix in any situation like my power jack that needs to control board I was thinking about trying to put the oo2 board on a board with a little feedback Transformer and a 5 volt Supply and maybe some mosfet drivers 4 the Power Jack Probably really aggravating monotonous answering the same questions over and over again probably most of the questions you guys get are really silly and make no sense at all I'm trying to get most of the control board question taking care of in this post So newbies can read this post and maybe not question you guys to death I am not smart nor wise when it comes to this stuff but I'm documenting with a lot of pictures that might help people out I really appreciate you commenting thanks again be warned i am good parrot but Dumber than a box of rocks |

I don't like giving advice, I would rather give none than the wrong one. But these are my thoughts, if someone can see bad advice here please speak up. Honestly I'm not wise enough to answer your question, however since your machine already runs and egs002 card and Poida has given you the modifications to make it more solid then that would be a good way to go. That is a fairly simple mod that doesn't require a lot of parts. (And you asked for a simple option) My ignorance caused many blown up parts, I have a working unit now but it was a long struggle. These are not simple machines to put together. Other options would be to purchase a pcb, buy all the parts, solder them all on, then if it was either a nano or Oz/Mad card you would have to wire it to suit your egs plug. If just one thing was wrong BANG there goes all the fets and god knows what on the control board AND power board. Then it's a big task just to find out what has blown. So building in steps and checking with the scope is how to do it. You now have a big late model power jack. You have 1 large and 1 small Ali boards fitted with egs cards, smaller one is blown up. In your shoes I would leave everything else in their boxes and sort out the small inverter you have blown up. Get that working and progress from there. If you want to start building any pcb's you will need a scope. With a completed power board once it is powered up the capacitors have a huge amount of energy to move things along, if something is wrong, that energy will blow things up. Taking the capacitor/s off that small board will allow you to use that as a test bed for various drive cards. If you feed the positive voltage from a restricted power source then even if something is wrong things will not blow up. That is the case with the Oz/Mad and nano cards, I'm not 100% sure if that is the case with the egs002, perhaps someone could confirm that? Now you can start it up and use the scope to check the wave, if something is wrong you can catch it before it caused any damage. Then you can fairly confidently put that card into other machines. This is a good way to check if a power board is correct, use a known working control card on the power board which has no caps, run it, check wave, then if all is fine fit caps and put it into operation. If you were to go down that path the nano would be my pick, you don't rely on the 8010 chip which is the brains of the egs002, instead it relies on the software that Poida kindly wrote and made available at no charge. Files to get the boards made are available for free too, thanks again Poida, Tinyt and others who made that possible. Cheers Caveman Mark Off grid eastern Melb |

Thanks renewablemark for all your time You make very good sense to me Guess what I've been looking for the whole time is a monkey see monkey do type control board we're if you know how to solder and put a component in its right spot then you can build a control board It would take us newbies a lifetime to gain all the knowledge wisdom an instinctive to know how to do a lot of this stuff It would be really nice if we have a monkey see monkey do project or two so newbies can actually build something that works so we can gain that experience and knowledge by hands-on experience I'm working on now is the little board I got the Hy 4008 in trying to figure out if I need to change resistors or anything else it has irf2907z in it right now I've looked up the datasheet on both mosfets I can't make head nor tails of it I know the gate threshold voltage is the same but I don't know if that's what determines if they're interchangeable I'm going to take video when done if they burn I'll have a video I have funny video of it blowing up last time need to find somewhere I can put it where all you guys can watch might get a laugh or two I have no scope but it's the next thing on my list when I can afford it Thanks again for your time I enjoy your down-to-earth common sense way of thinking Do you have anywhere where we can see some pics of your boat be warned i am good parrot but Dumber than a box of rocks |

Ben, you'll need a scope to check that your repairs on that little board worked. You can get crappy little lcd ones on ebay but you'll want a better one later anyway so may as well get one from the start. A second hand analogue will be fine. Pick one out and ask the fellas here if it will suit. I don't have a boat, must be thinking of someone else. Cheers Caveman Mark Off grid eastern Melb |

Hi BenandAmber, The way I look at the inverter control board is that its really *not* a monkey see monkey do assemble by number and solder it project. You also must never forget that you are dealing with lethal voltages, its relatively easy to get zapped while rummaging inside a life inverter case with your meter probes. You want something much simpler to start with and sharpen your knowledge about electronic parts and how they work. Then increase the complexity of projects until you know what each part inside does, thus gaining an elemental understanding of electronics since you did not get that with a formal education as most of us have. There are no safe "monkey see monkey do" shortcuts I can see here. As you say, it has taken many of us a life time to gather enough knowhow to tackle a complicated project like this and get it to work - with quite a few failures along the way  . I do learn from others more knowledgeable here but do have the advantage of a lifetime working on some aspects of electronics. By all means do continue your pursue of this electronic hobby but start with simpler projects would be my advise. If you want a working inverter, you did purchase one so why not use it as it is?

I will be using the one power jack as is the guy told me to keep the 50 Hertz 220 machine I need a control board for it that is 60 hertz I have wound a few Transformers with very good success i don't think I'll have any problems with that I just need to figure out how to turn this control board to 60 Hertz or build one I've been reading about the brain chip on it it's a little bit like the 8010 but a lot less straightforward I think you have to change a resistor out for the timing of the Hertz they use the same board for 50 hertz and 60 hertz it couldn't be that big of a thing to convert just no stematic nowhere I can find I can follow stematic I'm universal certified HVAC and a certified electrician I'm used to working with Mains voltage I'm used to working on small electronic boards but mainly simple stuff like changing out Transformers or desoldering a onboard relay and solder a new one or fuses checking sensors contacts very basic stuff I also repair appliances on the side I'm not a hundred percent new but there's a big difference from that and complex circuits Tinker you must be the one that I was reading about that had the boat you going to show us some pictures of it and tell us a few stories of where you've been Thanks for all the info you guys appreciate it be warned i am good parrot but Dumber than a box of rocks |

Ben you have been given the instructions to make it 60hz here in your own thread I really think you should make a friend close by who can give you some guidance on electronics one on one, doing it over the net may be troublesome. Perhaps some guys on fieldlines are local to you, or maybe a local electronics club/forum? Don't want to be rude, but I reckon you'll struggle on your own as I did. Having someone sit you down and go through things with you will most likely save you hundreds of dollars in potentially blown parts. You need to find a local mentor.

What is the part number of the chip and a picture of the pcb this is on. Not sure if I can help, but just curious. |

So I am going to ask. What would happen if you just used it like it is? I know nothing about American stuff. what I do know is that we have a lot of welder/gensets in Australia that are 60 hz machines and I have hooked quite a few to houses as backup generators and there is the odd switchmode power supply and ancient alarm clock that we have to remove because it is "50 hz only" but the rest of the stuff seems to function just fine. maybe a motor starting under load might not run? I dont know, I have never had a fridge or water pump do anything but run smoothly on 60 hz. all the modern stuff should work (i think) I have an old transformer for powering old American radios I run that at 50 hz 115-120v but I have never tried it with the new multivolt 100v-240v appliances. I'm confused, no wait... maybe I'm not... |

When I was testing my EGS002 based inverter on a 1.5hp 60Hz pool pump and have forgotten to change the jumpers, the pump made a much louder hum at 50Hz. |

Tinyt I am really excited that this has your interest  I think that resistor has something to do with it that I could be very wrong I'll leave that up to the experts Mc908mr32cfue on99d Qev1413  Thank you for your time I appreciate it be warned i am good parrot but Dumber than a box of rocks |

Renewablemark you have very good advice I will look into finding somebody around close that is just into Electronics I'm not sure if you was telling me that I should put a ESG002 card in the Power Jack with the link to the post you gave me if so I have considered that and we'll probably do that if nothing else comes about I'm not sure what size resistor and diode I have to change on the power jack to do that I have a funny feeling that we got a expert that knows what he's talking about on the case now hopefully that turns out Thanks everyone I appreciate you guys and gals be warned i am good parrot but Dumber than a box of rocks |

My eyesight is no longer good. Based on the picture I think that resistor is connected between pin7 (PTC0/AD8) and pins10/11 (VSSAD/VREFL). It probably has something to do with analog voltage reading. Unless we can reverse the design, schematic and code, I think this is an almost impossible task. If we can compare with another pcb configured for 60 Hz and if they are exactly the same, we can assume it is in the code as oztules said somewhere. So sorry Ben. |

No big deal Tinyt I am very grateful for u taking a look at it and giving your good advice on it now I know what I need to do Either find someone else that has the same board and compare it to this one Buy a new power jack control board which I really don't want to do I just don't trust them from everything I've read Use a ESG 0 0 2 do the modifications on it like poida told me to do on the little China inverter board build me a little board to put the card on that has a 5 volt Supply and a 12-volt Supply and a 120 volt to 12 volt teeny tiny step down Transformer for voltage feedback then run that through a voltage divider circuit to get the voltage down to a little under 3 volt I know it ain't quite that simple but I have a lot of determination and some good people on here to help me along the way Thanks tinyt be warned i am good parrot but Dumber than a box of rocks |

Warpspeed the genius has came up with a solution to this problem the crystal oscillator needs to be changed out to a 3.93216 to make this board 60 hertz instead of 50 hertz Yes you heard that right just need to change the crystal oscillator cannot thank workspeed enough I also appreciate all the time that everyone else has devoted to trying to figure this out I really appreciate it I hope this helps other people other than just me and I have a feeling it will Thank you everyone for your time be warned i am good parrot but Dumber than a box of rocks |

If Tony can do magic with an inverter he did not design, just imagine what the Warpverter is like. Thankfully, we have atleast 3 people on this board getting to it as we speak, so in a few months time we will have enough details for anyone to follow |
