yo griffin,
         its been blowing a gale here all day,a misty,drizzle that gets in everywhere,then the peasoup closed in,wet fog.
     yer gonna miss the drizzle in that thar hot climate.yer gonna be telling them thar locals about the great rain and lakes around mayo.
                    the first thing i would do,is stick up 8 x 80 watt solar panels  (12 volts x 17.5 vmp) =140volts in a single string,,charge into a 120volt battery bank= 10 x 12 volts. use the solar side of a 2kw turbine controller which dumps at 138 volts,,the dump will heat water easily on ordinary immersion then you have good supply of 120vdc,, use ups 2.7 kw (120vdc external battery feed) and bobs yer aunt. this outfit will give you lovely pure sine wave lecky,good for telly and pc.with the amount of sunshine you are geting there,it would be a sin not to use this setup.
  if you are stuck for any of the bits and bobs above,just pm me and i will point you in the direction of the 2.7ups or the 120volt solar hybrid controllers.

errrrrr,
        very nice of guy to offer his ups,, totally free,,lucky you griffin,!!!
      let me see,,,,,,,,, 5 x 80 watt panels (12 volt with vmp of 17.5) is rated at 87.5 volts but would deliver much greater volts in sunny porto,,
      so  straight in to 45 forklift cells = 90 volts with dump on one side set to 56,5(48 volt) and dump on the other side 42 volts(36volts).achieved by splitting the pack in two halfs to make the dump loads managable..
  then connect the ups to the lot and bobs your aunt.
      forum member,,,,,,,,,would this work, Huh? help help

I do not know Biff  , cause not too familiar  with UPS
And , If there is  a good hydro potential  , a too big battery might be an overkill

I would recommend a 24 or 48 Volt setup   and use  the powerspout battery charging unit or a  Navitron 230 AC  waterturbine  and AC couple this with the Off grid inverter /charger combi (the internal charger in the off grid inverter will than charge the battery from the waterturbine  in parallel)


And take my time to restore the waterwheel as well

or a  Navitron 230 AC  waterturbine


with all due respect to the owners of the forum - the low head turbines require.... fiddling? fettling? The OP has suggested 24/7 unattended power production is a requirement.


oh - and a griffEn is a town in austria.... http://en.wikipedia.org/wiki/Griffen Wink

Guy i thought more of a high head unit  , but still i do not know if Griffen can put in a pipe  further up the river  whistlie

A Navitron unit  would be a fast and low price install   for the time being , until the wheel is set up  or other ideas developed
