Evening all I am looking for recommendations for PCBs for my inverter build Ian using a single Aerosharp 3kw toroid I did see madness had a 12fet board that was tested good for 4kw but I think this was at 48v I am doing 24v Any suggestions? If so, who has them for sale? I was going to buy a ready made board from AliExpress But decided I would rather buy a naked board and populate it myself Still undecided of controll board aswell Leaning toward ozcontrol at the moment. I’m not confident in the reliability of Arduino due to Suffering 3 fail on me ( non critical operations) Thanks in advance |

inverter board If you got the dosh, i can definitely recommend these, i run 48v like others ,however this board comes ready and has handled everything ive thrown at it so far... just check over the board when you receive it, mine had 16v caps where they should have been 25v by markings. Wasn't a deal breaker and if even important, but i swapped them out anyways... I think it works !! |

That board does look reasonable Was thinking it might be cheaper to populate a naked board as I have SOME components here already. |

Also, I’m hoping to use the Aerosharp cabinet. I have a height of 260mm to play with. That board is 316mm |

Forget about using one box to fit it all in.....particularly with your first build. Mad sells the bigger board, John made it run on 24v, I think he may have changed one resistor for the tip 35.... can't remember. Poidas Nano control board has run my house for well past a year now.(I think I have a spare). The mad control board has a nano, but it's only for extra stuff, like low voltage shutdown etc, it doesn't need it to actually run the inverter. If you feed nanos a stable voltage they are reliable as an old tractor. Pity you wanted an OZ board, I just did a clean out and tossed one in the bin.

Damn that’s a shame. I am Going to take a trip to the local scrap yard today to see what I can find Hoping to do a trade as I have 2 batteries with shorted cells Who would you recommend speaking to, to obtain a power board and a control board? |

No cabinets unfortunately But I did swop the 2 batteries (70ah) for a 220ah Did a drop test on it (started at 12.2v). Showed good. So far since I put it on charge, it’s taken 90ah. |

Mark is quite right. Just get all the parts running together strung out along the workbench. It will be much easier to work on, you can see and reach everything much more easily. When its all finally tested and working, only then start thinking about any extra added features, any improvements, and how best to finally package it all. Once you have built a couple of inverters, it all becomes much easier to plan ahead and avoid mistakes, and build something that is neat, readily accessible, comes apart easily, and is generally a joy to work on. That all comes with experience. Cheers, Tony. |

Yes Stocky, as Mark and I have found out ,the Inspire box is just too small for all the stuff. I posted a pic of my gutted inspirit was too small for both the Torodial tranny and the boards.. Bruce Bushboy |
