Life at the end of the road

A breeze at last :-)

Three days without wind in February !!! hardly that unusual I guess, for I’ve had some cracking holidays here on the west coast at this time of year. Still it was pretty annoying if you’ve just put up a wind turbine, especially when these wispy little zephyrs from the west kept pushing the blades slowly around. Not fast enough to actually make any electricity but just fast enough to have me running in and out of the shed to watch the meters.

The problem being that I was using a much larger inverter than required so the settings needed altering. Trouble is that you cannot lower the ‘cut in voltage’ (Vpv start in SMA speak) until it’s actually cut in. So, it won’t actually ‘wake up’ until the wind turbine starts to generate, not so easy when there is no wind and you don’t know what you’re doing Smile  This SMA SB6000 inverter was set at 300v or something like that but eventually I managed to lower it to 250v and set it to ‘off grid’ mode.

SMA may well make the best inverters on the planet but their software is very ‘user unfriendly’, slow and has some really annoying quirks. Altering one setting will sometimes reset another completely different one back to a default setting. However the timely arrival of both John Macbeth and a little wind soon had the turbine producing.

A full 30w Smile Smile seems like an awful complex way of making enough power to illuminate a couple of bulbs Smile

It did get better right enough and by the time I’d left I saw the turbine pushing out almost a kilowatt in the gusts and there was still no more than a breeze.

The extra power managed to keep the caravan nice and warm via the convector heater on the 750w setting and start heating up the first set of dump loads.

That’s controller number 1, a Tri Star TS45 in ‘diversion made’ diverting around 750w into the first two resistors on the left. As you can see they get very hot, and that’s only a quarter their capacity!.

Pretty boring I guess but I’ve been somewhat engrossed in it these last few days and done little else.

My new neighbours on the other hand have been making great inroads into our old and sadly neglected her garden. Some of which went into the excellent home made Drambuie that we sampled with last nights sweet potato curry Smile

Hopefully though there’ll be major happenings at the new house next week, with the UFH and floor going in.

  2. Homemade Drambuie I had to look that one up. Just started on last years Damson Gin here.

  3. Home made Drambuie, eh? Googled that one and no two are the same. They seem to agree on rosemary and heather honey. Some add fennel and lemon rind. And bits and bobs. Google features no recipes from Scotland, how odd. What’s your favorite herb combination? I suppose the hard part is waiting 30 years for proper aging. Although Drambuie was only BPC’s daily dose anyway and nothin’ special, so I reckon “aging” is relative. I bought an “old bottle” off eBay for the bottle and was pleasantly surprised to see the bottle full and the seal unbroken and dated 1969. Twice as thick as the new stuff and much better! So if I make some and wait 46 years…. Nah, best drink it now before I forget what it’s for!

    • I do have a bottle of elderberry port i made in 1993. Still another 4 yrs to me next memorable birthday, hopefully I may have perfected Stilton making by then as well.
