I think the madboard was developed as an improvement for the powerboard used in the ozzinverter. It uses a proper npn/pnp drive for the mosfet gate drive on the powerboard itself, wich makes the gateloop a lot smaller. In the original ozzinverter the gatedrivers are on the controllerboard and gatesignals must go thrue the ribbon cable, wich works also just fine, I use the ozzinverter since 2018, and it delivers between 6- 7000kwh/year, 10kw peaks no problem.
I have some madboards but there is no provision to make a decent mechanical connection between the pcb and the heatsinks, this is better on the ozzinverter powerboard, so I never used them. But both designs have been proven for years now also in combination with poida's software.
I'm currently testing the wiseguy boards, wich is just superior to anything else we've seen over here. I only trade the ozz inverter in for that one. If you look at it from a pcb designer perspective you can't believe how well the madboard and ozz inverter actually works.
The build is like a marathon, no cutting edges, and use genuine parts. Make sure you have all the right testing gear. The build could look (or it is) expensive, but it's more like an investment for the long run.
