For testing, I decided to order two items – a 10A version and a 30A version to see what the differences between the two are. Taking apart the two units side by side, it's clear that the 10A version has just three MOSFETs while the 30A version has five MOSFETs. The internals. To fairly test the unit, I decided to create a basic standalone photovoltaic system using some spare parts left over from my PhD and others which could be adapted for use. In some ways, it's a demonstration of what not to do if you. After testing the MOSFETs, it was a bit of a game trying to suck out the very crusty solder from the PCBs. This required a co-ordinated effort with an iron on top and the sucker below. but I. Thus we reach the crux of why I was invited to test these regulators in the first place – the MOSFETs used within.
