Double the lifetime of an inverter?

Who the heck wants filters and maintenance. That is just poor design. Larger aluminum heat sinks and current devices require no maintenace.

That was the way it was when I started doing phone office equipment. But they wanted stuff faster and more intelligent. You can't just make
stuff bigger, because electricity only travels 1' per nanosecond, wires need to be short. Office space is precious, and its really hard to put
heat sinks on 10,000 parts. So fans went in, but maintenance is available. Bruce Roe
