Yes getting these boards is becoming a problem and I think PJ may have caught on.
I think PJ had no problem selling a few boards here and there, but I suspect there is little profit in selling these as I doubt they actually make these boards themselves, especially against the profit margins in assembling and selling their own Inverters, coughs & splutters!.
I have just checked, and the PJ LF, 15kw, 48vdc 230vac, 50HZ, pure sine wave boards are out of stock, The folk/agent you are dealing with, have NO boards at all for sale , they are supposed to be operating from Taiwan since 2008.
Each time I get some 15kW boards through these scattered around the globe agents, they actually always get delivered direct from PJ , PowerJack, DONGGANG, DALANG, CHINA.
If you are having difficulty obtaining these boards then contact

120v 15kW boards are still available from ..... http://www.ebay.co.uk/itm/121372307145?_trksid=p2060353.m1438.l2649&var=420314377003&ssPageName=STRK%3AMEBIDX%3AIT
If only we could produce a comparable board our selves?
