In keeping with the goal of keeping this simple, I do not expect people to have to purchase extra equipment to build the board. There are a few ways to mount the board to the Heatsink.   For this build I used an old Heatsink from a scrapped GT Solar inverter. I positioned the board so that all FET holes were away from any old mounting holes in the heatsink. You can purchase a 3mm Tap a 2.5mm drill and cutting oil from various hardware outlet. It just takes a bit of time to tap the 16 holes. FET Insulators: I purchased two meters of thermal mat, you can see the gray mat between the Fets and the heatsink. I'll look up the source and post a link. This is this same mat I used on my big inverter build, it's brilliant. You can of course use standard individual FET heat transfer insulators. There are other ways to get around having to tap the heatsink by using flat intermediate aluminum heat transfer bars. Both Wiseguy and I have used this method before. I will post more on this shortly. Once again, please don't post other mounting methods until I have finished posting the build, all that will do is make the build thread confusing for people new to inverter building. I will expand further once I have the basic layout and pictures uploaded. Thanks.
