New Marlec Rutland 1200 wind turbine ?

[Boo2]

Hi,

On Marlec's website here http://www.marlec.co.uk/new-rutland-wind-turbine/ it says something about a new Rutland 1200 wind turbine being shown at SIBS, anyone see it and have anything to say about it ?

Yup: Have the leaflet in front of me. £1195 inc vat. Apparently twice as much power as the previous model. Comes with mppt controller which also accepts 250W or solar. diameter 1220mm, turning radius 622mm, weight 7.8Kg.

Update on this (I've been reviewing wind gen literature this morning). Output of the 1200 is nearly twice the 914i (so is price of course) and the 1200 is lighter. I have to draw a line from the little power curve as there are no figures on this leaflet but it looks like *about* 35W at 10 knots, 110w at 15kts, 230w at 20kts, with high current protection kicking in to limit output to ~480w at 27kts. That puts output a little better than the air breeze which came out best for high power output in the yachting monthly test a while back but was criticised for not being practically user serviceable in another test I read:

The new rutland is more expensive and heavier than the air breeze but maybe it's more maintainable and marlec are of course based in the UK.

Is wind worth it any more? I was thinking about this last night. Putting a pole up for a wind gen would put shadows on the back deck where I propose to put a solar panel from one angle. I'd have a similar problem with panels on an arch.

Thanks to you both for the info. It is the low wind output that seems most interesting to me, I guess any wind charger will be fine in windy weather but keeping batts charges in low wind conditions is a different matter. The 914 had the best reviews in low winds and as it has a smaller diameter rotor that may tilt the balance for me too...

Sunrunner has a pinched IOR style stern without an arch and there is literally nowhere to permanently fix solar panels. I really don't want to just leave them in the cockpit and also don't like the idea of hanging them from the guard rails so I can only really use a WT.

Thanks again, something to think about anyway...

Looking further at the left hand side of this chart (and with apologies that the axes aren't finely labeled) the 1200 seems to start producing something at about 4.5kts with a linear rise up to 10 knots (~35-40w?) where the curve goes steeper. My interest is in loads of power as a liveaboard so the 1200 is interesting (but I have a nice area on the aft deck behind my centre cockpit which might cause a solar vs wind trade off). For your use case sounds like the 914i would be just as useful, and half the price (though a bit heavier).

Comparison from PBO group test March 2013:

The full comparison used to be available on the site of one of the manufacturers or importers, but it looks like they've taken it down. This bloke has a mirror, though: http://blog.marinfirsat.com/wp-content/uploads/2015/01/PBO-Magazine.pdf
