But is that good? I mean are the inverters getting worse because they get cheaper? Well, in this video I will be having a closer look at an absolute cheapy. I will test its performance, efficiency and have a look inside to see what is going on. At the end I will then try to upgrade it using the newest and greatest SiC MOSFETs. Let's get started!
