11.3. Hydro installations with room for improvement
This example has a few issues which could have
been avoided:
 The turbine is difficult to access for servicing
 With the door closed, the humidity in this
plastic enclosure can get very high. If you do
this ensure good ventilation to outside air.
 Plastic PVC pipe work could be tidier with
fewer bends
This example shows the turbine and inverter enclosed
in same structure. If you do this you should ensure:
 Ease of removal for servicing
 Good ventilation to limit humidity
Do not confuse AC and DC wiring runs when you order
your turbine.
On this site we were advised of a long cable DC run, but
it was installed on a long AC cable into the grid.
DC lines can have losses from 0-10% and higher in
some cases. AC cables need to be run with much less
loss or the inverter may trip, causing a nuisance. Always
follow recommended wiring sizes in your inverter
installation manual for grid connected inverters.
