Installation manual

FM60 tends to track down from the Voc and MC250 (in hydro mode) tends to track up from

the battery voltage. Once it gets to about 80 VDC input it will also have 1.6kW on the

display.

For more detailed information on the set up of FM60/FM80 , MC150/200/250, MC KID and

other makes of MPPT controllers refer to the new 2014 Technical Manual.

8.4.5. Visual optimization of PLT turbines

Once optimisation of PLT turbines is

complete, the turbine exhaust water

should be hitting the clear glazing at 90

degrees to the jet.

If the exhaust water bounces back

towards the jet then the turbine is

running too slow and you should pack

the magnetic rotor more (or raise the

MPPT voltage).

If the exhaust water travels through and

hits the opposite side of the casing then

the turbine is running too fast and you

should reduce the packing (or lower the

MPPT voltage).

Too slow Good Too fast

Top and bottom jet exhaust water is bouncing back

towards the jet, indicating turbine is running slow. A

little more magnetic rotor packing is needed.
