I've worked with both brands in the past, as well as Elgar in the 100 kW range. I found the CI to be a little more fragile than the PP units as I believe the current sharing scheme of the parallel AC modules was not the best design. I am thinking about this option, if I can find a suitable source for rentals. Solid state certainly has advantages like not having to carry cans of fuel.
