Also, watch for the surge current on start up of that machinery. Put a big lathe or something in there and the start up current could well be 3 times the nominal rated current, so you could end up with a 15% VD on start up.
I remember one fault report with an inverter on one of the forums that turned out to be caused by the inverter tripping out due to the massive voltage swing when a big bit of machinery started up in the shed it was connected in to.
Also when doing these calcs, if you could double check them to be sure to meet the 1% VD limit for a 16A solar PV supply that'd be much appreciated. Nowt worse* than having to dig the driveway up to install solar on the garage because the existing supply to the garage doesn't quite cut it for our purposes.
*ok there are actually quite a few things worse than that.
