Sorry Duncan, my internet connection is a friggen pile of crap. At least it's really really expensive, so that makes it all OK. haha. (one of the benefits of living in the middle of nowhere.)
I don't think the capacitors sitting for 10 days would cause any problems. But you should definitely use a precharge resistor when filling them up. Could you take pictures of the inside of the controller? Specifically, the holes through the control board where the M- bus bar is? You say you had replaced the mosfets before? Were the mosfets all you had replaced?
